Utilizing the equipment in University of Illinois at Urbana Champaign

Jenna wearing the C-Leg protection we’ve designed.

Hi guys, as the semester is over, I just wanted to tell you guys about the awesome equipments that are located all around our school! When I first took this class, I wish I had knowledge to these equipment, instead of searching for them here and there. I have a list of equipment that you guys can utilize to create prototypes in the future! Even though you are not an art major like me, you will have full access to these equipment I am going to be telling you guys. This process is based on my process of our group project, the C-Leg protection. I will take you guys through each step and how we came to our final prototype at the Make-A-Thon.

Located everywhere:

  1. Brainstorming and Ideation:
Jenna’s C-Leg sketch.

This is the very basic and most important step when it comes to design. In order to create a successful design, you need to specify the user and start brainstorming for opportunities. Come up with a few questions and search for your target user. Then ask them those questions and try to find an opportunity. For an example, our group found an opportunity to create a prosthetic leg protection for our user, Jenna. Based on the interview, you will start brainstorming different ideations. This process should be very quick and should always be open to opportunities. For me, the most important part was to keep in touch with the target user, so we know we are in the right track. So, our group drew a picture of Jenna’s leg and constantly referred back to the picture, to make sure we were on track. Throughout our entire process, we had to revisit this step multiple times, because we had to change out design. And this is natural. Do not rush this step, since you might get inspired by the most unexpected ideation.

Located in the Maker’s Lab:

  1. 3D scanner

After you have a good insight of your direction, the next step is to make a 3D model of the product you are basing off of. For my case, we had Jenna come in with her prosthetic leg and we had it scanned using the “Occipital Structure 3D Sensor with Precision bracket”. This program allows the user to scan an object and turn it into an Obj file which could later on be converted into a stl file by using “Scrulptris”. The more complicated the object is, the more time the program needs in order to read the data. For the prosthetic leg, it took us about 15 minutes in total to scan the entire leg. It is really cool to see the model slowly mold into a 3D file while you are scanning.

2. Fusion 360 and Cura

With the obj file is converted to a stl file using “Scrulptris”, you can open the file in “Fusion 360” if you need further modification. For an example, you can add more bulge to a certain area or fill in the holes of the object. If the file has a rough texture, “Scrulptris” will be able to smoothen out the rough surface of the object. This is very important. If you don’t smoothen out the surface and make sure you have no holes, the 3D scan will fail and you will have to start over all again. So, you should always make sure you do it right at the first time. After you send the file into Cura, you can change the density of the object. For my model which does not have a lot of body structure, I have a 15 percent density which is enough to be used as a model. You should ask the workers for better insights on which density to use because it will determine how long the 3D print will take. For our C-Leg model, it took us a total of 10 hours to print out the three separate models. This may not be applicable for everyone but with this C-Leg model, our team saved a lot of time and effort to make it accurate as the actual model. At the end, even without Jenna at the Make-A-Thon, the model fit Jenna’s C-Leg perfectly.

Located in the Fab Lab:

  1. InkSpace and Laser Cutting

InkScape is a digital program that is used in the Fab Lab in order to use the Laser cutter. If you have any experience with any of the Adobe Suite programs, it is very easy to learn. But even without any experience, you can learn how to use it within 20 minutes. The most important part is make sure the lines that will be laser cut should have a stroke of 0.01 mm and colored in red, RGBA: 255,0,0,255. If you would like to have vectors, just change the color to blue, RGBA: 0,0,255,255. Then save the file to a SVG format and print your file on the laser cutter. For my project, I used the laser cutter to cut the Acrylic according to our design. The laser cutter saves a lot of time and cuts the pieces precisely, so there is no wobbly cut strokes. Also, the laser cutter is great for anyone who is using brittle materials such as acrylic and glass. I think our team saved a lot of time during the Make-A-Thon by using the laser cutter.

2. Sowing Machine

Yishou using the sowing machine.

The sowing machine is great when it comes to sowing fabric pieces together. I used to learn how to sow my pants in fourth grade using my hands. But after learning how to use the sowing machine, I now only use the sowing machine to sow any embroidery pieces. When you use the sowing machine, you need to first feed the thread through the holes according to the numbers and make sure you have the feeding thread underneath as well. Pulling back both threads, you can then start using the sowing machine. With enough practice, the final product will turn out to have clean seam or even seamless if you flip it inside out. For our C-Leg protection, we flipped the seamed side inside, so the product looked very clean without any seam to be shown. You can use the fabric as a pocket. For an example, our group inserted foam pieces inside the two fabric and made it accessible with velcro.

3. Acrylic Bender and Heat Gun

Lastly, the heat gun is my favorite equipment to use in the Fab Lab. It is also one of the most dangerous equipment to use, due to how hot it could get. With maximum heat, it could burn your skin very badly, so it should be always be used with heat resistant gloves. Another similar product is the acrylic bender. This product only applies heat in a straight line, so it takes longer to bend objects. I found out that this equipment is best when it’s used to precisely bend an object in a certain angle. For our project, we first used the acrylic bender to get a general shape of the mold. Then we used the heat gun to warp the shape according to the 3D scanned C-Leg. When we were using the heat gun, we had to make sure we protected the 3D scanned C-Leg with fabric, so the 3D canned C-Leg won’t melt. With enough caution, the acrylic bender and the heat gun is a great tool to use.

Conclusion:

Throughout this semester, I’ve discovered all these gems located in our campus. And it was an awesome opportunity to learned how to use all of these equipments. I don’t think I would’ve been exposed to any of these if it wasn’t for BADM 357 class and the Make-A-Thon. This course has definitely made me hungry to explore other equipments located around the campus and I am going to give it a try. I will continue to use these techniques I’ve learned and use it create other prototypes as well. I also hope that this guide will attract other non-designers to take a chance and explore the beauty of designing prototypes.

Nouvo

August of 2016 changed the lives of my closest friend Amaury Saulsberry, who I consider to be a brother of mine. He created Nouvo shortly after his younger brother was diagnosed with a severe case of GERD, commonly known as acid reflux. It took about four months for him and his family to get the proper diagnosis, and by the time they did 80 percent of his brothers esophagus was damaged.

This led to the beginning of Nouvo. Nouvo is a healthcare tech startup that has created a smart pacifier that monitors  pH and temperature levels in infants saliva as a biomarker for acid reflux. The scope of the technology goes beyond just that as this data of the child’s vitals could potentially pinpoint many other ailments. This smart pacifier is patent.

This is our smart pacifier and integrated app

Through the University wide resources Amaury and the team were able to get act on entrepreneurial endeavors. Course in TEC, BADM, ARTD, Engineering  and even attending workshop and office hours for EIR ( Entrepreneurs In Residence) at the Research Park helped Nouvo get started. We were able to create our first working prototype with resources and skills learned here at the university.

Even now we’re finding more and more helpful resources the university has to offer. We’ve been able to accelerate our rapid prototyping with the use of Fusion 360 and the maker lab 3D printers. We’ve also upped our fabrication by utilizing the tools at the FabLab. They have a wide range of filament options, laser cutters, and milling machines. We were actually able to use the milling and 3D printing at the FabLab for the circuit board that housed our prototype. These Helped us be one of the health marathon winners this year.

To date Nouvo now has a team of six. All of whom are fellow students ranging from engineering to industrial design backgrounds. The advisory board is comprised of doctors, an FDA lawyer, financial specialist, and much more.

Nouvo showcasing at EoH 2019

Currently Nouvo is awaiting patent acceptance and the FDA approval process. The product is considered to be a class II device and could take upwards 9 months. During this time we are working on developing our other connected health products. We are working on acquiring additional funding that will go towards perfecting our MVP.

How 3D Printing is Influencing the Medicine Industry

3D printing technology has evolved throughout the years, and it has drastically reshaped many industries. In this article, the focus would be put on its impact on the medical industry. Specifically, this article would touch on the features, current application, and controversial areas of the 3D printing technology.

3D printing is different from traditional technology in several different ways. This article would focus on the three main benefits 3D printing bring to the medical field: customization, low-cost and flexibility.

Customization

The first feature of 3D printing is customization. Depending on the individual needs, the model or the product can be tailored to individual users. At the same time, the model or the product can easily scale up depending on the volume demand.

3D printing is becoming more and more widely used in the hospital setting. One application of 3D printing in the hospitals is the rehearsal of surgery. With 3D printing technology, the patients’ specific conditions can be printed out and examined before the actual conduction of the surgery. With rehearsal on the patients’ specific models, the success rate of actual surgeries is much larger. In addition, because the doctors can practice and train on the specific model, it takes less time to carry out the operation. As a result, the patients are exposed to the environment for a lesser time. This further reduced morbidity and mortality rate.

Low-Cost

The second feature of 3D printing is low-cost. 3D printing is generally cheaper than the traditional method. In a conventional way, the mold is designed for larger production, and it requires a larger volume to cover the capital investment. As a result, many products are more expensive to the end customers. This makes some products unaffordable to end customers with smaller disposable income. On the other hand, because 3D printing can be designed for each individual, the cost for each type is drastically cheaper. It doesn’t require a building a specific model to carry out a new type. The lower initial investment enables 3D printing to be low-cost even for small volume production.

One example of how low cost benefits the customers is the application in prosthetics. Traditionally, it is costly for customers to get customized prosthetics because of the sunk expenses related to building the model. With 3D printing, the cost of manufacturing prosthetics is much lower which makes prosthetics more affordable to end patients.

Flexibility of Location

The third feature of 3D printing is its flexibility of location. Traditionally, the manufacturing of the products takes place at the manufacturer. Then, depending on the channels, the products would go through several intermediates before it comes to the end customers. With 3D printing, it is possible that the features of the product are transmitted digitally. Changes can be made throughout the supply chain. In the medical context, the end hospital or drug stores can print out the pills at the very last minute depending on the patients need. The fact that it can be carried out at the last step enables more customization opportunity. Since nothing physical has been produced in the middle steps, the costs of switching are much lower compared with the traditional method. The distribution and storing cost can be reduced to a minimal extent. This makes 3D printing more affordable for patients.

One example of how the flexibility of location benefits the customers is pills. The pills can be printed out at drug stores. This makes it very convenient for customers to get the drug they need. In addition, combined with the customization feature of 3D printing, the pills can be customized to each individual so that the individual doesn’t need to take as many pills as they do with the traditional method. The shape of the tablets can also be altered to fit individual consumers better.

Controversies

Although there are many benefits and current application of 3D printing technology, the technology still has some controversial areas. Until those areas are fixed, it would be hard to apply 3D printing technology widely.

Unrealized expectation

The first controversial issue with 3D printing is the unrealized expectation associated with the technology. The current accomplishment of using the 3D printing has been exaggerated by the media, the governments or even researchers. As a result, the general public doesn’t have a clear image of what the technology can achieve and what the technology can’t achieve in the current stage. For instance, the application in bioprinting and organ structure is at the preliminary stage. However, the outcome of the current usage is exaggerated. The consumers are not aware that the technology is not mature enough to be carried out to all cases, and it will require more time and money until the wide application become realized.

Regulation

A second big issue with 3D printing is regulation. While the production becomes simplified with 3D printing, the potential impact of counterfeit products become problematic. This is especially true in the medical field. For instance, if customers buy fake pills, their health conditions would be worse. The government needs to set rules associated with the technology to ensure it is controlled and monitored. The same principle applies to copyright concern. The law needs to define to what extent it is legal to copy a 3D printing model.

Conclusion

The 3D printing technology has benefits in customization, low-cost and flexibility of location. With those features, 3D printing has been making a significant impact in the medicine field. However, certain controversial areas remain unsolved, and it is critical to solve those concerns before the broad application of 3D printing.

The Bioprinting Industry at a Glance

When I first chose to take this Digital Making course, I had no experience with Design or 3D printing. I knew 3D printing technology was becoming more advanced and accessible, so I enrolled in the course to learn more about the technology itself and its impact on different industries. In the first few weeks of class, I researched topics related to Digital Making in order to expand my knowledge of the field. One aspect of Digital Making I found very interesting was Bioprinting. Not only did the possibility of printing something living blow my mind, but I realized that this could have a drastic effect on the Medical industry. Thus, I chose to conduct further research on the Bioprinting industry: what has already been accomplished and where the industry is headed.

What has already been accomplished

The greatest opportunity I see with Bioprinting is organ transplants. According to the National Center for Biotechnology Information, “154,324 patients waiting for a [transplant] in the United States alone in 2009. Among them, only 27,996 patients received organ transplantation and 8,863 patients died while they were still on the waiting list.” If Bioprinting becomes more accessible in the near future, it will drastically decrease these numbers due to more available and cheaper organs. Thus, hundreds, if not thousands, of lives could be saved each year in the United States.

Some phenomenal work is already being done in this field. In Poland, researchers are working on printing an artificial pancreas. The goal of this research is to create a functioning pancreas that will help those who struggle with diabetes. With an increasing rate of diabetes and thus more transplants, this bionic pancreas would affect thousands, if not millions, of people and save countless lives.

Pancreas transplant research.

Another recent advancement is a Korean company, Rokit Healthcare, is testing a new method for treating lesions through skin grafts. The method involves using a patient’s autologous tissues and cells to then print a graft. Once the graft is printed, the doctors will place it on the patient’s wound and the skin cell will regenerate. Additionally, researchers in the industry have successfully printed DNA molecules onto glass slides utilizing inkjet printers. Inkjet printers have also been used in cartilage repairs and other types of cells.

However, there are still some obstacles to overcome with inkjet bioprinting. For example, the high heat of the nozzle may over-dry the cells. One approach to overcome this obstacle is to prepare the bioink in a water-based solution to prevent drying and clogging of the nozzle. This method of tissue engineering research is also very expensive and time-consuming, which makes it not very feasible. Moreover, there is the possibility that cells could be damaged in the printing process. Small nozzle sizes necessary for high resolution printing puts more stress on the cells. However, controlling the concentration of cells in the bioink allows researchers to control the number of cells in each ink drop, which could help minimize cell damage.

The future of bioprinting

Returning to the idea of solving the organ donor shortage issue, Dr. Anthony Atala, the Director of the Wake Forest Institute of Regenerative Medicine, is a leader in this area. He gave a TED talk in 2011 where he introduced a printer that could print a working kidney. Today, the kidney still has not been successfully transplanted into a human, but Dr. Atala stated that his lab’s research “has shown that 3D printed bone, muscle and cartilage structures, when implanted in animals, succeed in creating a system of nerves and blood vessels that integrate into the body.” However, this research is still being conducted and is not ready to try on patients.

Dr. Anthony Atala presenting his 3D-printed kidney at his TED talk in 2011.

The possibilities of bioprinting in the future are endless. Currently, most research is in the experimental phase. Living cells, tissues, and organs have been printed, but they are not yet in the stage of surgically implanting them into human bodies. There have been successful transplants in animals, but not humans yet. Because the industry is still in the Introduction phase of the industry life cycle, I predict that within the next ten years, successful transplants of different types of organs will take place and bioprinting will become more widely used once it is approved by the FDA.

Impact on the medical field as a whole

As further research on bioprinting is conducted in the forthcoming years, bioprinting will become more advanced and common. This will increase the availability of now-scarce organs and decrease the cost of transplants. Furthermore, companies are starting to partner together to conduct more research. For example, L’Oreal and Organovo, a 3D bioprinting company based in San Francisco, teamed up to explore 3D printed skins for cosmetics testing.

In addition to printing living cells and tissues, medical professionals have successfully printed body parts out of other materials and implanted them into people’s bodies. One recent success story is Professor Mashudu Tshifularo and his team of surgeons in South Africa have implanted a 3D-printed middle ear. This landmark operation consisted of the hammer, anvil, and stirrup ossicles that were 3D printed with titanium. Professor Tshifularo stated that “The operation went fantastically well and we are very excited.” Thus, it is evident that 3D printing is the future of the medical industry, whether the materials being printed are living or not.

Week 10 Summary: Make-a-thon Pre-Event

The ultimate goal of the Digital Making Seminar course is to create a functioning prototype of whatever it is that each team is working on by the end of the Make-a-thon, taking place from Friday, April 12th, 5:00 pm to Sunday, April 14th, 2:00 pm. What makes this event so exciting is that it not only involves the Digital Making Seminar students but also the students from Dr. Deana McDonagh and Jim Kendall‘s studio class as well as Jeff Ginger‘s Marketspace class. Although the point of the event is to provide the space and resources for the participants to make their ideas come to reality and not to compete against each other, because many external people see the value of what we are doing, we have judges, sponsors, and expert users and mentors to guide us through the progress.

As the date of the event approaches, Dr. Vishal Sachdev, our professor for the course, set up a pre-event, where the participants came together to meet each other as well as some of the mentors and expert users. The pre-event began with the introduction of the make-a-thon with details regarding the schedule and the resources that we would have access to. From the Fablab to Architecture Annex on campus, we are fortunate to have been provided with access to many resources. We are all very excited to utilize the resources to develop on the ideas that we have worked on so far throughout the semester.

While sharing the details of the event, Dr. Sachdev, as well as Dr. McDonagh, reemphasized that the purpose of the event is to design with the expert users and mentors in different opportunities that have been identified. We are not solving any problems or challenges. It is critical for the participants to remember this as we want to constantly keep the users in our mind while constructing prototypes and receive feedback by working with them.

After going through the details of the event, we were introduced to a few of our mentors and expert users as well as new ones. Each one of them took the time to introduce themselves, sharing their stories to inspire us.

John and Isaiah, two of the new expert users that have been introduced, shared how they adapted to the struggles that they faced. For example, John, whose condition does not allow him to have enough grip strengths to use his fingers to pull apart a sock to put over his foot, kindly demonstrated the solution that he found for it.

John’s sock which has been modified to fit his need.

As pictured above, with help from his mother, he simply had three loops sewed around the neck of the sock, allowing him to insert his fingers through them and to tug on them. This simple, yet brilliant idea inspired many of us, encouraging us to think of simple ideas and to look for inspiration from the daily objects. We realized that by doing that, we will be able to come up with things that many users would have access to and find easy to use.

Steve, a representative of Clark-Lindsey, also shared the stories of the residents and their needs in the local retirement community. From the challenges of holding the phones to video chat with the family to the danger of falling due to dementia and pre-Parkinson’s disease, he shared how we can leave a big impact on many different types of users through this event. This sharing inspired some groups, such as the team that is working on developing a product to help the people with prosthetic legs to improve the balance to do yoga, to think of ways to expand the user base.

Afterward, we were provided with opportunities to talk with the expert users and mentors to ask questions and to receive feedback on the ideas that we have been developing throughout the semester. Some teams were also able to talk with students from other classes to see if any of them would be interested in joining the team.

As we continue towards the make-a-thon, most of the teams are moving into the prototyping phase. So far, we came up with many different ideas and developed on them, constantly receiving feedback from the expert users. However, we understand that there will be different challenges that will arise when we try to make the ideas tangible, which is why prototyping is important. From low fidelity prototypes to 3D designing through Fusion360 and printing the product, we will be experimenting with different ways to develop the prototypes. We are all very excited to continue to work on our ideas and look forward to presenting them during the make-a-thon!

Silicone and 3D printing – is this the future?

I am a Computer Science major however, I have always had a passion for art. For years I’ve been seeking ways to utilize both of my passions for tech and art interchangeably. After seeing pictures of Gucci’s FW18 show in Milan I was stunned. Models were walking down the runway with their heads! I was so intrigued that I did some research into how Gucci made this happened.

MILAN, ITALY – FEBRUARY 21: A model walks the runway at the Gucci show during Milan Fashion Week Fall/Winter 2018/19 on February 21, 2018 in Milan, Italy. (Photo by Pietro D’aprano/Getty Images)

“Representing the growth and self-awareness of a person as well as being conscious of one’s evolution, models walked the Gucci Fall Winter 2018 show holding replicas of their heads. To recreate their faces, the models’ moulds in silicone and plaster, and the models were scanned at Makinarium’s headquarters in Rome six months ago for a virtual 3D impression to capture their expressions. This advanced technology is then finished hand texturizing by artisans in the factory’s laboratory.”

The company Makinarium is famous for creating special effects for numerous movies. After finding this out I decided to dig deeper. Silicone has not only been of benefit in the art world but also in other industries such as the medical and aerospace industry, In an article by Alina Cohen it states, “[silicone] shape-shifting potential has inspired everyone from astronauts to plastic surgeons: Neil Armstrong wore silicone-tipped gloves during the first-ever moonwalk; cosmetic surgery has long relied on the material for breast implants;”

3D printing is used alongside silicone molding and casting. 3D printing and silicone casting have many similarities. One is that they are useful for making duplicates and prototyping. However, the traditional material used to 3D is a lot harder than silicone. Using them interchangeably allows for one to still leverage the ability to prototype efficiently while also being able to dedicate certain materials to certain aspects of the design. One team utilized both 3D printing and silicone casting to make a tail prosthetic for an alligator. In an article by Clare Scott, it states,

“The team 3D printed the model and used it to make a silicone cast. That cast was then used to make multiple prosthetic tails for Mr. Stubbs. Why didn’t they just 3D print a wearable prosthetic? While 3D printing has been used to create numerous prosthetics for animals, an alligator tail is especially large, and the team would have needed a large-scale 3D printer to print the prosthetic all in one piece. There are certainly 3D printers that could handle the job, but it would have been a time-consuming print, especially since they wanted to make multiple prosthetics. It would be easier to make one 3D print, use it to make a mold, and quickly cast several pieces.”

There are now 3D printers on the market that can print with silicone. In an article by Farai Mashambanhaka it states, “Wacker Chemie, a leading chemical giant, unveiled the first silicone 3D printer. This development brought great options in critical areas of application, especially in the health and medical areas, where silicone is considered to be biocompatible and tear resistant.” Researchers at the University of Southern California leveraged 3D printing silicone as they found a way to 3D print self-healing polymers, “Researchers at the University of Southern California Viterbi School of Engineering have done just that: created 3D-printed rubber materials that can quite literally fix themselves without human intervention.” (Tracey Schelmetic)

3D printers that print silicone are utilized in the medical industry especially for the new development of breast implants. After numerous failures with breast implants erupting surgeons are seeking new ways to create safe breast implants one-way of accomplishing this is through using 3D printers that print silicone.

3D printing and silicone will continue to integrate in the future if technology. I think it is amazing that this intersection ranges from art to the medical industry. It really speaks to the power of STEAM.

Introduction to 3D Printing Technology in Food Manufacturing and its Impact

3D Printing Technology

3D printing, also known as additive manufacturing, is a technological process that can bring a digital file into a three-dimensional solid object through adding layers by layers of material until the object is formed (“What is 3D Printing?”). 3D printing consists of a series of additive manufacturing technologies, including “selective laser sintering (SLS), fused deposition modeling (FDM), laser-assisted bioprinting, micro-extrusion, etc” (Derossi et al., 2017). The history of 3D printing technology can be traced back to the 1980s. In 1981, Hideo Kodama published his account of a functional rapid-prototyping system that could build a solid, printed model through building up layers that corresponded with the cross-sectional slices of the model with photopolymers. In 1984, Charles Hull invented stereolithography that allowed designers to create 3D models using digital data, which could then be brought to a tangible object through the rapid-prototyping system, which was the start of 3D-printing technology (Goldberg, 2018).

In the past decade, 3D printing has brought significant impact to many different industry sectors, including engineering, medicine, aerospace, art, education, as well as food manufacturing (Derossi et al., 2017). This research paper will focus on the impact of 3D printing in the food manufacturing sector.

3D Printing in the Food Manufacturing Sector

3D Printing in Food Manufacturing

3D printing in food was first introduced by researchers from Cornell University through extrusion-based printing. Now, there are four types of 3D printing techniques widely used in the food manufacturing sector. These 3D printing techniques include extrusion-based printing, SLS, binder jetting, and inkjet printing (Liu et al., 2017).


Types 3D Food Printing Techniques

Extrusion-based printing

The extrusion-based printing technology is usually used in printing hot-melted chocolate, soft dough, mashed potatoes, meat puree, cake frosting, processed cheese, and sugar cookies. This technology can also be used in printing non-traditional materials like algae and insects.

Selective Laser Sintering (SLS)

SLS technology is usually used in creating complex structures that are made up of sugar or sugar-rich powders. This method can create various attractive complex structures that could not be produced by conventional ways.

Binder Jetting

The method of binder jetting is usually used in constructing edible structures using sugars and starch mixtures. This method allows the production of a wide variety of colorful and tasty edible objects like various kinds of complex sculptural cakes.

Inkjet Printing

The technology of inkjet printing is usually used in surface filling and image decoration by dispensing edible liquid on the food surface to create appealing images. In this way, this technology is best in creating different images with high resolutions on edible structures like a biscuit, cake, and crackers.

Impact of 3D Food Printing

The application of 3D printing in food manufacturing can bring positive impacts on food and consumers through its highly customizable nature. It allows people to obtain personalized and digitalized nutrition, tailored shape and dimension, customized internal structure and taste (Derossi et al., 2017). It can also simplify the supply chain and enlarge the source of available food material by using non-traditional food materials, including insects, high fiber plant-based materials, and by-products from plants and animals (Liu et al., 2017). However, the application of 3D printing in food manufacturing also leads to societal challenges (Deloitte, 2018).


Benefits

Customization & Enlargement of Sources of Food Materials

In terms of the positive impact the 3D food printing, a major positive impact or potential that 3D food printing has is that food can be personalized and digitalized so that the required nutrition and energy is provided accordingly. In addition to this, the enlargement of sources of materials used in the fabrication of food introduces people to the more non-traditionally expected food and a greater variety of options to choose from.

For instance, the US Army has a very strong interest in the application of 3D food printing in military food primarily due to the following facts:

  1. the technology ensures that the production of meals will not be at a shortage on the battlefield;
  2. meals can be personalized, digitalized, and customized depending on each soldier’s need for nutrition and energy;
  3. the technology offers more options to soldier’s food in terms of the materials used in the fabrication of food (Liu et al., 2017).

In addition, NASA also funded Systems and Materials Research Corporation (SMRC) to investigate the possibility of applying 3D printing for manufacturing food that meets food safety, nutritional stability, and acceptability requirements during long space missions (Liu et al., 2017).

Moreover, as many countries are starting to face aging problems, the issues of nursing home residents having chewing and swallowing difficulties are becoming more serious than before. Softer texture of food will be easier to swallow (Liu et al., 2017). In this case, personalized meals that are produced based on different individuals’ needs for nutrition and energy, physical ability to chew and swallow, and age becomes very useful. In addition, smaller pieces of food will also be easier to chew and swallow for elders. In this case, the ability to tailor shape and dimension very important to produce the meals based on the different individual needs too.


Reproducibility

Another key benefit of 3D food printing is its nature of reproducibility. 3D printing enables chefs to produce exactly the same design for multiple times, especially for those designs that are especially difficult to produce by hand and reproduce. With today’s technology, the ability to elaborate designs and reproduce the special 3D designs helps the production becomes more rapid and ensures the quality of the food design as oppose to hand-made food (Koeing, 2016). In the high-end dining industry, the ability to reproduce complex food design is one of the major elements of fine dining because the quality and reproducibility are highly valued by consumers.  


Simplified Supply Chain

3D food printing can also simplify the customized food supply chain. The robots (food printers) will facilitate the implementation of a strategy that produces the product as orders come in with low overriding costs. The production facilities can be near the end consumers, helping to simplify the customized food supply chain and bring the products to consumers in a more economical manner, specifically with a shorter period of time with fewer human resources being used and higher affordability (Sun et al., 2015). This becomes very beneficial to consumers because it leads to lower prices of customized food as the production process can precisely control the inputs and outputs of the 3D printed food and faster delivery of food to the hands of consumers. The 3D food printing technology can also ensure consistent quality of food products.


Challenges

Although current 3D food printing technology gives us the ability to control the flavor, texture, color, nutritional makeup, shape, and reproducible quality of food. However, the advancement of this technology also raises concerns of the edible materials and other ethical and societal challenges.

Challenges of Material

As the 3D food printing technology gains more popularity, there are some concerns toward the use of edible material, like the health concern for food as the temperature fluctuates. “During the extrusion process in 3D food printing, temperature fluctuations can also represent a health concern for food because the heating/cooking may promote microbial, bacteria, or fungus growth. Thus the industry needs to follow e.g. FDA guidelines regarding appropriate food temperatures” (Pérez et al., 2019). In addition to the temperature fluctuations, food materials with high viscosity and high consistency index are hard to be extruded from the nozzle. The precision of the 3D food printing process will also be affected if the food needs to be printed faster. This is because increasing the printing speed of the 3D food printing process currently requires a larger nozzle, but when the nozzle becomes larger, the precision and quality of printing the shape of the food will become worse than expected. How to adapt to the edible materials used to 3D print food becomes a major challenge.


Ethical & Societal Challenges

In addition to the challenges on the 3D printed food fabrication materials and processes, the ethical and societal implications that 3D food printing brings to the table are more serious.

For instance, “human nutritional needs has been shaped and met by eating whole, natural food. These contain trace elements microbial flora and fauna we are continually discovering the significance of” (Deloitte, 2018). In this sense, we have rich knowledge about what we have discovered as key nutritional elements that human needs for survival, energy, and growth. However, as we are continually learning about nutritional needs, we have to acknowledge that we have limited knowledge about human nutritional needs. We only know the needs that we have discovered, but we don’t know if there are any nutritional needs that are fundamental that has not been discovered yet. If a large portion of the diet is made up of 3D printed customized food, there may be a possibility that we are leaving out key nutritional needs that we have not yet noticed. If there is a risk of unknown malnutrition problems with the 3D printed, personalized, nutrient diet, would the promoting of the benefits of meeting human nutritional needs through customized 3D printed diet still be ethical?

Moreover, like other technologies, 3D food printing is also a process of automation. Whenever the automation topic is brought up, one critical societal question we need to think about should be whether automation that can bring convenience to people is worth the value to exchange for our daily activities, especially the social aspect of preparing and sharing natural food (Deloitte, 2018). To some people, the value of the social aspect of preparing and sharing natural food may be much greater than convenience. To these people who value their daily social activities highly may find a hard time adapting to the usage of 3D food printing because such automation takes away the happiness that can come out from making food. But to other people, this may be the opposite. As a result, the controversy around automation continues.

Architecture. 3D Printed.

Once of the most influential factors in my decision to enroll in the class was seeing the partnership announced between ICON and New Story in early 2018. After settling down post 2017 crypto crazy, I began to look at other technologies which could impact the developing world. I had fallen in love with enabling digital and social finance and in 2018 I slowly began shifting my focus to housing. I had battled and worked through last mile internet solutions through my time with Mesh++, and now I wanted to delve into scalable solutions to solve homelessness, because everyone deserves at least that.

            While researching this topic, I familiarized myself with someone we all should know, Charles Hull, the inventor of stereolithography. This was a process discovered over 30 years ago and it has just begun to go mainstream as 3D printing. It blew my mind that this was a technology discovered before the internet. As with all innovations, it takes time and large institutional investments to drive the price down, but with companies such as Formlabs coming to prominence in the last decade, we can surely say 3D printing is here to stay.

           Nonetheless, concrete 3D printers are typically the type which are used currently in 3D printed houses, so it is still a niche within the industry that is not necessarily accessible or affordable for the average person yet. With that taken into account, they are typically reasonably priced, rarely crossing the $20,000 threshold. However, even the everyday firm architect experiences significant value adds from incorporating the 3D printing process into their workflow.

            For starters, 3D printing can help clients better visualize and scale a potential project. Mini-cities and structures could be easily developed to show urban planners how another building would influence the landscape, and let clients get a sneak peak of their dream home through scaled down models. It also allows for simple remote collaboration, as architects could edit the digital files anywhere around the world, and then print them remotely themselves.

Additionally, by moving this manual process to a digital format, architects will inherently save time and money throughout the design process. Yet the most important aspect could be what is the equivalent of the open source code community. By lowering the cost and time effects of creating digital models, architects will be more encouraged to start repositories of their 3D designs, allowing the greater community to leverage and build off them. I can’t wait to see the GitHub equivalent in the architecture or design industries!

            On the higher level, we see 3D printing continuously used more to 3D print houses directly. ICON is currently leading the field, with their printer being able to create communities with houses up to 2,000 square feet! The previously mentioned partnership with New Story subsidizes these types of houses for the developing world, specifically targeting families who live on less than $200 per month. It is reassuring to see industry trailblazers continuing to conduct business with a social impact; that is our responsibility as early adopters of disruptive technology.

            Even though I can’t wait to own my mini-empire of personal 3D printed homes all across the globe, 3D printing is making an impact in architecture far beyond replacing traditional home construction (as if that wasn’t enough already). Just this month, a team of Boston University researches unveiled a shape which blocks 94% of sound. The ring-like figure is “mathematically designed, [and made from a] 3D-printed acoustic metamaterial [that] is shaped in such a way that it sends incoming sounds back to where they came from” (Fast Company). 3D printing is literally spearheading an architectural and design movement which will serve as our infrastructure backbone for at least the coming decades.

           The influence of 3D printing in architecture has arguably even been felt. We’re finally closing in on an era of affordable housing in which entire communities can appear out of nowhere in a matter of days. Architects will delve into an age of newfound collaboration and digital innovation which will stimulate real estate development at a lower cost. And maybe scientists will even 3D print more ridiculous innovations which alter the sensory output of our environments. 3D printing will disrupt architecture in a way few expect, but in a way which will never leave our world looking the same.

How 3D Printing is Revolutionizing Fashion

As 3D printing increases in popularity and becomes more common, many industries are evolving to include the technology. A great example of this that many people do not normally consider is the fashion industry. As a user who was unfamiliar with 3D printing in the beginning of this class, I understand people might not grasp the impact 3D printing plastic can have on fashion. However, 3D printing has major implications for design, texture and innovation for fashion designers. 

A great example of this is LabeledBy a design studio in the Netherlands that works to incorporate innovation into their textiles and garments. The studio strives for personalization and sustainability within the fashion industry. LabeledBy says they have been able to use Ultimaker and 3D printers to make personalized garments that uniquely fit a person’s body. During their interview, LabeledBy explained that the 3D printer they use has been optimized for garments and textiles. The 3D printer can print all materials and they are making even more changes so they can print with more experimental and biodegradable materials. They also make sure to use materials that are suitable or the washing machine! LabeledBy is a great example of a company that is innovating the fashion industry with 3D printing. 

Example of clothing created by LabeledBy

Another great example of 3D printing in the fashion industry is within movie props and costumes. In the movie Black Panther, the costume designed for Queen Ramonda was created with a 3D printer (see picture below). The technique used to create this design was SLS or selective laser sintering. It involved using lasers to heat a powder and fuse the particles together. The particles were fused layer by layer and then the excess filament was removed. A CAD software was used to create the 3D costume and was then tailored for the actress’s specific measurements.

Queen Ramonda’s dress

The designer of the costume, Julia Korner, had previously worked on 3D printed designs for Haute Couture collections (including items for Chanel and Herpen). Haute Couture is the most exclusive, expensive segment of the fashion industry. This segment is so high fashion many people have never even heard of the designers. Even celebrities don’t normally participate in the Haute Couture fashion segment. This segment is meant for true fashion enthusiast who spend millions on a single piece only to never wear it and to save it to be admired for generations. Therefore, it is absolutely crazy to think that 3D printing is invading the Haute Couture fashion segment. This really has the ability to decrease the exclusivity of a fashion piece and allow it to be affordable or within reach for average consumers.  

3D printing has also disrupted the luxury fashion industry and caused many concerns for designers. Luxury fashion is what is still a very high end fashion segment but includes more well-known brands such as Louis Vuitton, Hermes, Gucci and Burberry. There is some overlap between luxury fashion and Haute Couture (example Chanel), but a brand can meet luxury fashion criteria and still not be high end enough for Haute Couture. The biggest concern of luxury brands with the introduction of 3D printing is intellectual property rights infringement. Global import of counterfeit goods is already over $500 billion a year however, with 3D printing luxury brands expect this number to grow. However, the article mentions how it is still important for luxury brands to embrace 3D printing and view the technology as a way to create a personalized product for an affluent customer.

Personally, I view this shift in the industry as positive and I wish luxury brands would embrace affordability. (I understand this counterattacks the idea of it being a luxury brand.) I believe if everyone has the opportunity to access “luxury” fashion (even if it is 3D printed and “counterfeit”) socioeconomic disparities based on fashion would reduce. Sometimes people are quick to judge based on the clothing and brands a person wears. However, that isn’t fair in my opinion; just because someone does own a Chanel purse it doesn’t mean they are any less of a person. 

3D printing is also helping to increase the sustainability of the fashion industry. Currently, the fashion industry is highly criticized due to large amounts of clothing that end up as waste in landfills. However, with 3D printers’ designers are able to print new designs and create less waste. Designers are also looking into biodegradable clothing that could be 3D printed. According to St. Catherine University researchers, 3D printing has the potential to change the entire fashion industry and allow ready to wear fashion companies to create less waste. Within the shoe industry, 3D printing allows designers to easily prototype and reduce waste associated with making multiple shoe models. 

In class, we were able to understand how 3D printing applies to the fashion industry when we visited the Fab Lab in Champaign, IL. We actually were shown a fabric that had 3D printed thorns on it for a costume. This is only the beginning of the capabilities 3D printers can have for the fashion industry. As people continue to experiment it will be interesting to see how the fashion industry innovates with this technology. 

Highlighting the FabLab: A Fabulous Resource

The UIUC FabLab is filled with unique resources not available anywhere else on campus. Even so, this semester is the first time many people in our course stepped foot in the building. I wanted to use my “Once a Semester Activity” to highlight this phenomenal place, the people inside who make it so accessible, the amazing projects that are done in this building on a regular basis, and how this location has been an asset to our course.

First Time FabLab Goers

The basics of the FabLab can be found on their website, but I think personal anecdotes are also useful in understanding the place itself. For me, the first time I entered the FabLab was in November 2017 when I was speaking with the staff about setting up a space for Stay Glassy. Stay Glassy is a part of the Illinois Enactus non-profit, creating products from glass waste. This was incredible of the FabLab to offer some of their space to student makers who had never known this space existed previously. Everything about the building is about enabling others to make what they want by giving them the skills and equipment to do it on their own. I felt this from the moment I entered the building, and while this was a niche reason to visit in the first place, I think that is common in what draws many people from campus. When you are looking for a specific tool, this place will catch your eye. When you are looking for a creative outlet, this place will catch your eye. When you are looking to make something, this place will catch your eye. While our BADM357 course brought many students for the first time, many students stumble upon this location on their own pursuing their own passion projects

Surveying some of the individuals in the FabLab, I found a common thread. Each had come either for a course, through an organization, or to work on an individual passion project. While each specific reason was different, there were many common feelings. A lot of students felt overwhelmed walking in for the first time. This was fueled mainly by the sheer number of resources, being in a new space for the first time, and being surrounded by people they had not met before. The inside of the building is also quite a juxtaposition to the outside, and the transition can be a lot. However, after overcoming the initial shock, understanding the layout, and learning the etiquette, all of the students I interviewed said they loved coming back. Going to a new place with tools you don’t know how to use can inherently be overwhelming, but the culture of the space is welcoming and fun. It is open to experimentation and artistic expression.

FabLab Etiquette

When you enter the FabLab for the first time, you may be overwhelmed as well. For that, I’d like to present a list of “What to do as a Newcomer” that will perhaps ease your transition to the space.

  1. Sign In – When you first arrive, you should sign-in on one of the tablets near the door. Signing in does not notify anyone but rather helps the FabLab keep track of who is coming and going from their facility. You don’t have to write in a particular reason for being there or fill all of the fields, but signing in is a courtesy.
  2. Find a Staff Member – There is an electronic board across from the main door that lists the staff on hand. While you may not see any of them immediately, it’s also very possible there are staff members around that aren’t listed on the board. The best thing to do is ask the first person you see if they can point you to a staff member. Many people in the FabLab are return visitors and can likely point you to someone if they themselves are not staff!
  3. Ask for a Tour – Wandering is great, but inefficient. The FabLab is filled with tools, and it’s likely you won’t know what they all do at first glance. Asking a staff member for a quick tour as a first-timer is a very easy ask and useful even if you are going in for one very specific task. Then if you ever need to go again, you’ll be familiar with the layout and the space’s capabilities!
  4. Test Yourself – Try a new example tutorial to test yourself on a new tool! If there’s a tool you are interested in but have no idea how to use it, check the tutorials page on the FabLab website. They have step-by-step instructions on anything from using SewArt to embroider clothing to creating silicone moulds to solar powered USB chargers. Starting here to learn a tool or technique is a great choice, and you can ask staff if you get stuck on any particular part.
  5. Pay for Materials or Tool Time – Some of the equipment and materials requires payment. Everything is very inexpensive for how incredible the resources are! Details about rates are posted around the shop by the machines they apply to while materials can be bought from a staff member. The FabLab accepts cash and card so it’s very accessible!
  6. Sign Out – Congratulations! You completed your first FabLab visit and hopefully overcame the first-time jitters while learning something new! On your next visit you can keep exploring, learning, and pointing out staffers to newcomers who see you as a senior FabLab-er.

Who’s at the FabLab?

The FabLab is filled with passionate individuals. In my visits, I have met people creating things for class, for fun, for profit, for their mom, for anything! There’s no good reason to not hang out at the FabLab! The FabLab is a community space, and they truly turn no one away. It is not just a student resource. It is open to community members and regularly hosts programming for kids in the area. One of the biggest users of the FabLab in the summer is summer campers! FabLab staff organizes many weekly camps all summer long to introduce kids to the space and teach them some really awesome skills. They also organize workshops for undergraduate student groups and you can browse the topics here.

Let’s See this Place!

While this far from encompasses everything the FabLab has to offer, it is the FabLab from my perspective.
