We can all relate to the surreal feeling brought on by the coronavirus as we struggled with being caught in this bizarre new world that was difficult to believe yet impossible to ignore. We couldn’t help but feel shocked as it unfolded — it was unprecedented — although there had been a dreadful buzz in the air heading straight for us from miles away.
As our nation is sieged with controversy, climbing death rates, trepidation and uncertainty, I wanted to find some uplifting, local COVID-19 stories that would serve to brighten our spirits. This is part 1 of 5 stories to be posted.
Stephen Chininis — Local Hero
Industrial Designer and Inventor at Chininis Product Development Group — Chininis Designs, Georgia Tech educator, Curiosity Lab mentor and Peachtree Corners resident Stephen Chininis wondered what he could do to help during the crisis. “We all got the sudden shock that the world was changing. I suppose if you’re a poet, you write poems about it. I’m not a poet. I make things. I’m an inventor,” he said.
Behind Every Great Man…
In early March, his wife, former Assistant Principal of Norcross High School, Maria Chininis, suggested he make face shields when she realized her colleagues were in desperately short supply. Mrs. Chininis currently works with a sports medicine group at Northside Hospital.
Equipped with a 3D printer and a laser cutter, her husband got to work in the garage, creating a model to be vetted by the infectious disease staff at Northside. A few modifications later and Chininis was ready to go, well before most. Some were producing one-time-use face shields, but Chininis had specifically received requests for shields that could be cleaned daily and reused.

The Power of 3D Printers
“The companies who produce face shields couldn’t meet the immediate demand. They were ramping up production the same time we were. We beat them; the 3D printers of the world beat them, we got… [face shields] into the ICUs. It’s just a get ‘er done attitude,” Chininis stated.
Regarding his problem-solving approach to life Chininis said, “I’ve always had that attitude; it came from my parents and my upbringing. I think that’s something we need more of. I’m really glad to see my students acting that way. They’re asking how they can help. It’s very infectious. Everybody wants to be a part of making things better.”
He provided over 300 face shields to hospitals all over the U.S. “3D printing has some weaknesses but the strength is, if there’s a problem and you need to solve it, you need a prototype, I can design something, print it overnight, and the next day, I can have the answer,” Chininis said of the low-run production solution he made use of so ingeniously.
“What’s cool is you save the files of all these different things you make, and you can reproduce them again whenever necessary,” Chininis beamed.
Trial and Error
An injection mold is a better way to produce face shields, but it’s a much more expensive endeavor. The mold alone could cost $30,000. It requires special equipment and machines, so the tooling price is prohibitive if you’re only looking to produce a few hundred of them.
With a long-spanning career of 30-plus patents and licenses for over 100 inventions under his belt, Chininis found himself Googling and talking to doctors, trying to find out what kind of plastic other Personal Protective Equipment (PPE) products were made of so he could use that same grade for his shields.
“It wasn’t as smooth as it sounds,” he recounted, and told of misadventures with industrial plastic companies that would suddenly cancel orders due to COVID-19.
He modified his designs several times to be able to continue making the visors with whatever plastic he could find, often with variations in thickness. The downside: “Sometimes the plastic was heavy, so it wasn’t as comfortable to wear, but better that than not having a visor,” Chininis offered.
An initial model made of acrylic crazed after sitting overnight, forming tiny cracks all over the surface of the shield. Two of his face shields melted when left in direct sunlight for too long but they were returned and easily replaced.
“3D printed plastic is susceptible to high heat. At 150 degrees it will start to bend and melt,” Chininis explained.
Then it was a matter of finding someone who stocked the right plastic in the thickness needed. “It’s all very tedious. Thankfully, my wife helped me,” he noted.
The Cost of 3D Printed PPE
Materials for one medical grade shield run about $10, and the two-hour time frame needed to print it, $50. Yet Chininis offered his products for free to hospital staff. Some recipients offered to help defray the cost of materials for the production of subsequent shields.
Ratted-Out by the Neighbors
“I’d like to point out how lucky I feel to live in Peachtree Corners,” added Chininis, a resident since 1986. When neighbors saw him toiling in the garage in response to the needs of medical staff, the news soon reached CBS who rushed to cover the story in March.
The design that got him recognition was a sturdy yet comfortable mask, made of high-quality plastic that was resistant to chemicals and could easily be washed and reused for several months.
“Everybody wanted one from San Francisco, Louisiana, Atlanta, to Chicago and New York,” he said. His Instagram and Facebook posts resulted in requests pouring in.
When a Community Pulls Together
During the busiest time, he turned to Curiosity Lab at Peachtree Corners for an extra printer to ramp up production. Chininis had helped set up the 3D printers there when it was still Prototype Prime, and he has been instrumental in the printers’ maintenance ever since.
He also enlisted the help of a former student in Marietta who could make a batch of 10 masks per week to help fulfill the orders.
Face Shields of the Future
The demand from hospitals started to taper off in early May. It has shifted from PPE for hospital staff use to mask for use by everybody else. Chininis explained, “We’re starting to see a second wave of PPE coming along, not designed for the ICU but for other people. We never really thought about this. How do we protect everybody?”
Chininis is now producing made-to-order shields: “Tell me what you need, I’ll make it.” People don’t want to take medical grade visor shields away from the ICU, but they do want something to make visiting their parents safer. He’s created a simpler design that can be fastened to a baseball cap.
Chininis meets these challenges with enthusiasm; it’s part of why he loves design so much. Effective design is the result of knowledge, and he has a passion for learning about each new need.
“I try to anticipate what may happen. It’s hard because there’s a lot of conflicting information,” he said.
“People are getting restless. It’s not safe yet and it won’t be for a good while. I’m inclined to listen to doctors and medical people. We did have a great effect on COVID-19 already, we did flatten the curve. I don’t think relaxing [Stay at Home Orders] to a great extent is going to be helpful. It’s going to come back. There are going to be hot spots. The question is how big and where will they be, in our backyard or someone else’s?”
We all Need to get Back to Work — Safely
Chininis was working with dentist Emily Chen, DDS, MA Prosthodontist, the day of our interview, custom designing a visor that would allow for the dental loupes to fit underneath with a headlight affixed to the top. “She’s going to use it over the weekend and let me know on Monday what we should change,” he explained.
He’s also gotten a request from a turkey factory in Minnesota that has asked for face shields that they can attach to their hardhats.
A Humble Hero
When I thanked him for everything that he and his wife have done to make things a little better during this frightening time, Chininis replied: “Honestly, it’s nothing. You do what you do. If you’re a doctor or a nurse, you go to the hospital and you help there. If you drive trucks, then you help with the food supply.”
“I’m really proud of the folks I know who have not been whiney in the face of this crisis. They’ve taken on a ‘We can figure this out’ mindset.”
His unpretentiousness had me on the Coronacoaster of emotions. Eyes welling with tears, I needed him to know that his ingenuity and generosity are everything, especially to those who have loved ones on the front lines.
At this point a blubbering mess, I managed to choke out, “Most of us feel helpless — like there’s nothing we can do.” To which he replied, “But that’s not true. By writing an article, you’re doing something. Right? It’s just a matter of everyone figuring out what they’re good at.” That’s when I would’ve hugged him if I could, but alas, distanced Zoom interviews are the new normal.
