Arts, Science and Technology Come Together for Covid-19

A fairly universal experience when people heard their workplaces, houses of worship, restaurants and every other kind of business or organization were shut down because of health mandates.

People suddenly had plenty of time, but what to do with it?

One such person was Eric Hess, one of the glass artists at Sanctuary Art Glass near downtown Shreveport. He and his partner in glass, Michelle Pennington, were just two more citizens cast adrift on the shores of idleness. Hess was noodling around Facebook when something caught his eye.

A friend in Colorado had begun making glass splitters, sort of a crystalline “Y” shaped contraption, that could let the output of one medical ventilator be shared by two patients. Colorado, like Shreveport and most of the rest of the world, was experiencing a shortage of ventilators where they were needed. This seemed like a good, short-term solution, so Hess jumped on board the glassmaking bandwagon.

Hess, if you are unfamiliar, is a high-octane, Type A personality. This project was just up the bored artisan’s alley. It wasn’t long before he had jumped ahead. “I got on a nationwide initiative with five glass artists from around the country to make these available for the hospitals,” he said. They studied the medical requirements of the splitters and soon were taking their first steps in producing them.

Before long, Hess and his colleagues had begun turning out prototypes and testing them at hospitals; one went to West Jefferson Hospital in New Orleans.

It wasn't long after that that an acquaintance working in a local hospital shared that masks were scarce at her facility, but what were really needed were full-face shields. Those would protect health-care workers who were in close contact with patients with respiratory issues.

With an extensive background in fundraising, Hess started looking for donors to purchase the needed personal protective equipment (PPE), but it didn't take long to find out such gear was as scarce as toilet paper. More searching showed that the National Institute of Health had published a design that was 3D printer-compatible. He called another acquaintance, Matt Hopper, who owns Ark- La-Tex 3D Technology Company and works as an engineer at Libby Glass.

"We've got a small 3D printing company with four or five machines," Hopper said, "and we designed a really large 3D printer several years ago, and all of this stuff has been on display at SciPort for the last few months.

“This all started about three weeks ago. Eric gave me a call. He said, ‘I’ve got a couple of folks here from LSU Medical Center that are seeing these 3D printer face shields, and they're saying that they could use something like that. Is this something you could do?' I said, sure.

"So, we made a few samples, and [Eric] took those to the hospital. The next day he calls me back and says, 'Matt, they want a thousand.' And I said, 'Whoa!'" At that point, Hess said, “We realized this was much bigger than we thought.”

Stunned, but undaunted, Hopper rounded up his printing equipment and started printing the plastic forms. They then got with LSU- Shreveport and Bossier Parish Community College “because we knew they had technology labs,” according to Hess.

"For about 16 years, I was an adjunct instructor teaching 3D drafting and design and manufacturing at BPCC," Hopper explained. "I knew they had eight to 10 printers there." He asked if the college would come on board; they agreed, and soon were printing the headbands.

Dr. Julie Lessiter is the vice-chancellor of strategic initiative at LSU in Shreveport. She was contacted by Shreveport Economic Development's Brandon Fail, whom Hess had reached out to about the collaboration. Hess put her in touch with Hopper.

SWEPCO to assist in the endeavor. Two students who had 3D experience were also recruited along with a faculty supervisor.

“We went in and built up a 3D print lab. Everything we do is with emergent-tech. We have this 10,000-square-foot space that used to be our bookstore that we’ve converted into what we’re calling a Cyber Collaboratory. That’s going to open this fall.”

"It takes about an hour to print one headband, and we have about 12 printers going right now. We stood up this lab thinking we'll be printing for about four weeks, which is why we're really grateful for the external funding from SWEPCO to cover the cost of materials we're using," she said. Their current output is about 100 headbands a day.

After LSU joined the team, Hopper said Demetrius Norman from the Northwest Louisiana Makerspace called to say they would like to help. Hopper said, “The next thing you know, Eric calls and says, ‘The mayor wants to have a meeting.' 'The governor's calling.' 'Somebody from the team of the mayor of New York is calling saying we'll take as many of these things as you can make as fast as you can make them.'" Hopper said it takes 20-30 minutes to print the headband piece. They needed to up their game. “My kitchen table we set up with clamps and boards so we could take this clear plastic and cut it to size for the front [of the face shield].”

Looking for a solution, Hopper called Raytech Industries in Bossier City. He wanted to know what it would take to create an Line Mold & Die in Shreveport, heard about the project and got involved as well.

Hopper’s day job at Libby Glass was furloughed like many others, so Hopper asked permission from plant management to use the machine shop. The plant manager not only threw in free use of the shop but supplied a machinist as well. The mold could be finished before this issue of 318 Forum reaches you.

The team got a call from the state of Louisiana asking for a request for quotes for two million units. Hopper told Hess that it would be possible to produce upwards of 6,000 a day. If demand rose, they could add additional injection molds at $60,000 to $70,000 each, which Libby is funding.

At one point, they were injection mold which could be used to massproduce “I’ve started calling all the social workers, Once she knew what was needed, she went to her bosses, who okayed the use of space, which is currently under construction. They also obtained outside funding from AEP/ turning out 300 units a day, but they realized the process was too slow, and as the word spread around a desperate medical community, the orders began to flood in.

the headbands, the time-consuming piece of the project. He was told he’d need a mold designed and manufactured to the right specifications. Paul Morse, who owns Red [grocery store] cashiers, anyone who is dealing with the public one on one, hospice workers, home health workers,” Hess said. "So, we’re getting these things out as fast as we can to everybody to cover the community. We’re looking at giving away about 10,000 in the Shreveport-Bossier City area.”

Hess and Hopper did a local television news interview and, according to Hopper, "the next thing we knew, the story had gone all over the country. I got a call from a gentleman in Houston who works for Curtis Wagner Plastics. They had started making the clear portion of the face shields and wanted to know if I was interested. I thought, yeah, I’m spending hours cutting these things on my kitchen table; yeah, I’m interested.”

A partnership was hammered out, and the Houston firm began supplying the clear face shield fronts.

The Governor's Procurement Office also sent letters statewide, which has resulted in requests from all over the state.

“We’ve gone from a 3D printing operation with four or five printers and a little network with BPCC and LSU-S to a full-on, largescale manufacturing operation in record time,” Hopper noted.

It’s not hard to imagine the pathos that this teamwork evokes. “What’s really touching, I’m getting individual calls. ‘My daughter is a nurse; can you please give me a shield?’

‘I'm a hospice worker, I'm 69 years old, and I'm going in to work with people that tested positive, and I have no protection.’ I have over a thousand orders from doctors and nurses at hospitals that are saying we don't have the supplies.”

That problem is not isolated to Shreveport- Bossier City. A medical professional in a distant state explained the situation there: "There is still a drastic shortage of PPE at our hospital. N-95 and surgical masks are rationed. We were told that a large percentage of the hospital's stock was stolen in the early days of the pandemic, presumably by panicked or opportunistic employees.

"Despite being disposable, we are having to put them in a paper bag and wait five days before we can use them again, rotating them out. They become stained and smell, from hours and hours on our faces. Everything we ever learned about safe PPE use and infection control from our first classes in nursing school has gone by the wayside. We all know it's wrong, but acknowledge that we are in crisis-mode, and nothing is best-case scenario anymore.

“We received donations of handmade cloth masks for our workers. We were using them as covers for our surgical masks that we were having to conserve and re-use, to try and extend their lives by keeping them clean. Administration has forbidden us from using them.

“I’m not blaming our hospital system for lacking enough PPE. That’s out of the hands of most all hospitals. I do, however, resent them limiting what we are able to do to protect ourselves and give ourselves some sense of personal security with whatever options we have at our disposal.”

In the meantime, Hess has also teamed up with Sunny Gulley and Shreveport Sews. “We started getting a lot of calls from nursing homes and others saying they want the fabric masks,” Hess explained. “I got with Sunny and asked if she could coordinate a citywide effort for fabric masks. So, we’re getting all the donations for fabrics and thread. Now we’re supplying to the food bank, nursing homes and others. We’re trying to meet all those needs also.”

Looking ahead to the return to normalcy, Hopper said, "What I see after this is the medical community or the government reevaluating the need for certain levels of inventory. Especially of items like [PPEs] in preparation for something like this [pandemic] to happen again. I think we’ll satisfy this short-term need, but I think there may be more of a long-term need as organizations re-evaluate their demand for some of these inventories.”

Hess and Pennington have a more artistic future vision. “Once this is over, that’s it. We will be back to glass. We started with the glass splitters. We just couldn’t say no. If there’s a way anybody in the community can help anybody else, I think you should try whatever you can to get us all through this. We want to go back to being glass artists and producing beautiful glass and having classes and having outreach in the community.”

Necessity is the mother of invention, or so said Plato a few thousand years ago; but it can also be the genesis of an outpouring of community spirit and cooperation.
