In the span of one day, the founders of Houston-based Lazarus 3D received calls from emergency room directors and physicians and vice presidents of hospitals explaining a dire need for personal protective equipment — like surgical masks and face shields — for medical professionals in the front lines of the battle against COVID-19.

"We stopped everything we were doing," says Jacques Zaneveld, co-founder of Lazarus, which makes 3D-printed human organs for surgeons to practice on. "We've moved 100 percent of our focus on developing PPE."

Now, Zaneveld with his co-founder, Smriti Agrawal Zaneveld, have manufacturing orders in for 700,000 surgical masks weekly and have designed a non-FDA approved face shield, which they have ordered a few million of. The duo has taken out a short-term loan to front the cost of the medical equipment and are now looking for the right customers to buy these new PPE products. All hospitals and medical professionals in need of supplies can head to Lazarus' website to request more info.

"Our personal feeling has been to do whatever we can do to build as many as possible," Jacques tells InnovationMap. "It's very stressful because I'm borrowing money that we don't have in order to set up these production lines."

On the other side of town, 3D printing nonprofit TXRX has reprogramed 30 of its 3D printers to make PPE. The nonprofit is working Memorial Hermann to quickly prototype and test items made with materials they can get their hands on.

The Center for Disease Control has relaxed some of the requirements for PPE in light of the crisis and shortage, and Roland von Kurnatowski, president at TX/RX Labs, says that has helped speed up their efforts. But, the biggest challenge, he says, has been to quickly get together a design and prototype for Memorial Hermann to give them feedback so that they can then produce the products.

"I think there are a lot of people out there producing devices, but I think the problem is there's not a lot of clarity around materials, quality, and acceptance. People are doing what they can with what they've got," says von Kurnatowski. "Our hope working with Memorial Hermann was to make sure we are devising and testing devices that are functional and appropriate.

TXRX is also relying on Memorial Hermann and others in the medical community to indicate which PPE devices are most needed. Currently, the nonprofit is printing 10,000 face shields for Memorial Hermann, but also has designs for N95 respirators, surgical masks, a positive air pressure respirator (or PAPR), Tyvek suit, and even a portable shield for the intubation process.

Von Kurnatowski says the Houston community can get involved by donating to TXRX's GoFundMe campaign. The 3D printing process is quick and local, but expensive and out of budget for hospitals, so TXRX is taking a loss on its products it is creating. The organization is also looking for people who might have 3D printing materials or experience to volunteer — TXRX has about 20 people working on this but hopes that number ramps up to 60 to 80 people helping out.

Crisis also brings the community together in their time of need — that's what Zaneveld says he sees happening.

"Everyone who is at all involved in the medical space in engineering in Houston is trying to put stuff out," Zaneveld says. "We're sharing information and trying to work together to support each other."
