Richard Kennedy turns to his research at 麻豆视频 to help create better, safer personal protective equipment (PPE) for health care workers.

鈥淲e knew design was important, but I don't think any of us understood how much of a difference it makes until we started working with Richard,鈥 says Steph Sharp, CEO of Vancouver-based tech company 3DQue. 鈥淚t's huge.鈥

In April 2020, Emily Carr University MDes student joined 3DQue鈥檚 engineers and entrepreneurs as the company鈥檚 first design intern. 3D-printing typically requires a technician to be present to monitor the work, ensuring adjustments are made where needed. This means the output of any 3D printer is limited by the stamina of its human attendants. 3DQue builds software and equipment to automate the 3D printing process, meaning a printer that can theoretically run day and night until a job is done.

Recruited for his background in 3D printing and design, Richard spent most of his first month on the job building and calibrating printers so the company could help produce personal protective equipment (PPE) and medical supplies for the fight against COVID-19. But these routine tasks quickly led to more experimental work, as Richard moved from installing printers to setting up the prints themselves.

The power of design thinking

鈥淎 designer who understands 3D printing is critical,鈥 says Steph. 鈥淲e have seven 3D printer guys here and as clever as they all are, they're not at Richard's level of design.鈥

She recalls one design Richard worked on 鈥 a T connector for a nebulizer 鈥 which was particularly challenging to print because of its shape. That鈥檚 because 3D printing happens in layers, printing one thin film of plastic on top of another until the final shape is born. This iterative process means items with an overhanging component鈥攍ike the top bar of the 鈥淭鈥 for the nebulizer joint 鈥 are impossible to print without using supports to prop it up. Those supports add costs to the manufacturing process. They also use up extra material, which then has to be cut away with a sharp blade by a technician after the part is finished printing.

鈥淪o, what did Richard do?鈥 Steph recalls. 鈥淗e literally just turned it.鈥

Normally, T-shaped parts, like this one, have to be printed with large supports under both sides of the 鈥淭鈥 (left). In Richard鈥檚 adapted design (right), the joint is printed at an angle, reducing the size of the supports.


鈥淭hat's the power of design,鈥 Steph says. 鈥淚t seems like such a simple solution, but you have to think so differently.鈥

鈥淗ow we interact with our products and objects in the world as designers is very different from people from other fields,鈥 Richard agrees. 鈥淚t鈥檚 a different mindset when approaching problems.鈥

But as much as Richard brought a new perspective to 3DQue鈥檚 work, the internship has also shaped the way Richard is approaching his research.

鈥淲hat I really admire about 3DQue is that they鈥檝e brought free space for experimentation into their own facility,鈥 says , an associate professor at 麻豆视频 and Richard鈥檚 graduate supervisor 鈥淪ome of what Richard was able to do was really play a serious play that works into the push-pull of innovation.

Finding a third space for innovation

Richard鈥檚 master鈥檚 research explores the intersection of computational design and traditional craftsmanship, like pottery or woodworking. It builds on the work he鈥檚 done throughout his degree at 麻豆视频鈥檚 . The Centre, which Keith co-directs, is interdisciplinary and collaborative, with a long history of industry partnerships and exploratory research.

鈥淲e work with industry on developing new and novel workflows that integrate 3D printing and advanced manufacturing, as well as faculty-led research at the intersections of craft and digital technologies,鈥 Keith says. 鈥淥ne of our key interests is engagement: through curriculum, through graduate research, and also through that third space which is outside of the credit system鈥攊ndividual agency.鈥

For Richard, that third space has been his internship. 鈥淚 was able to do things that are related, very heavily and very directly, to what my research was engaging with,鈥 he says. 鈥淚 was able to take something that, in my research, was a very theoretical or speculative proposal and really see it in a very real sense.鈥

At the core of Richard鈥檚 thesis are questions about how computational manufacturing methods, like those used in 3D printing, can be combined with artisanal production. 鈥淭here's this romanticism that exists around craft practices and this old-world version of going to a local artisan who makes a product to fit a specific need,鈥 he explains. 鈥淚t is obviously a bit absurd in today鈥檚 society that everything in your life would be made by hand by somebody you met locally. But there is some version of that which is a possibility with 3D printing.鈥

One approach to making that possibility a reality is what鈥檚 known as parametric modeling. Through this process, computational designers can lay out the groundwork for all-but-print-ready products, but leave just a few design choices, or parameters, open for customization. Those open parameters can later be defined by other makers, allowing manufacturers with limited computational expertise to tailor products based on their individual needs.

Richard鈥檚 'Ripple Vessel' features an experimental design that can be customized to create unique 3D printed bowls, vases, cups, and other ceramics. Creators can explore possible customizations and create their own print at ShapeDriver.com.

鈥淭his is the thing that's really cool,鈥 Richard says. 鈥淵ou can create objects that are completely unique, and you can create them at a fairly rapid and automated process.鈥

Unlocking the potential of parametric modelling

Richard had the chance to apply this approach at 3DQue when the team started producing face shields for COVID-19. 3DQue had started printing the shields using a design they鈥檇 found online. It was solid and functional, but it wasn鈥檛 perfect: it took about 75 minutes to print a single shield and the final product didn鈥檛 fit everyone on the team comfortably.

Again, Richard made some minor adjustments to the design, reducing the time it took to print and creating options in different sizes. But beyond these modifications, he also applied lessons from the parametric modelling he鈥檇 been studying at 麻豆视频, enabling the team to print serial numbers directly onto the face shields.

Adding these unique identifiers makes a product traceable and, ultimately, recallable 鈥 which is important for any consumer product, but especially for medical equipment. 鈥淚f you put a product out into the world and it fails, you need to be able to trace it back to the manufacturer,鈥 Richard explains. 鈥淵ou need to have numbers on every single one that comes out.鈥

鈥淎s far as I know, it was the first time in the world that this had been done,鈥 Steph says of Richard鈥檚 serialized redesign.Not only did it make it more compliant from a regulatory perspective, but it also made it faster to print, which is cheaper for a manufacturer. He brought the material down by two grams, and then he made it more comfortable for the end user. It was pretty innovative.鈥

Richard isn鈥檛 quite sure where he鈥檒l end up after his internship ends, but he鈥檚 looking forward to putting more of the ideas from his master鈥檚 research into practice. 鈥淭he big thing about working with 3DQue has been the practicality of it, the realization that it鈥檚 possible,鈥 he says. 鈥淚t's not just a pipe dream.鈥
