My name is Eric Bubar. I’m the associate professor of
physics at Mary Mount University in Arlington, Virginia.
What I’ve been doing to help out with the Covid-19 response
is creating 3-D printed PPE. So, the design I’m using is
something called the face shield. I have two designs, this
one and this one. These are actually not my designs. They
are open sourced. They’re created by other individuals.
So, this was created by a company named Prusa Research.
They’re very well known in the 3D printing industry for having
very reliable 3D printers. And then this is the Verkstan
design made from a Swedish design firm.

These are what I am creating, not what I came up with, just
using the open sourced designs that were made available for
anybody that has a 3-D Printer to download and create.

What is 3-D printing? It’s a way to do manufacturing. It’s
called additive manufacturing in some circles. And what you
do is you take some plastic in the form of a filament and you
extrude it through a very, very hot nozzle. That nozzle melts
the plastic and it lays down a little bit of plastic in whatever
shape you want. As soon as the plastic hits the, what we
call the built plate, it kind of cools off and solidifies. Then the
little nozzle will go up just a little bit and draw another layer
on top of that and build up whatever 3-D shape you can
imagine.

So, if you look very closely at this 3-D print, you can see that
there are different layers. So, a 3-D printer builds up
whatever shape you want, layer by layer by layer.

So altogether, this one takes probably about four hours to
fabricate one, whereas this one, the 3D Verkstan, this 3D
print takes about 40 minutes to print one of these little
headbands. And then, the shield itself is a very thick
overhead transparency that takes about, maybe, five
minutes to hole punch, three hole punch to get it to pop onto
these little pegs. So, this one takes, maybe, 45 minutes to
create one.

So, currently the shields are being used by a variety of
different healthcare professionals, in hospitals, in community
health centers, in elder care facilities. People like that these
3D printed shields are sanitizable so they can reuse them.
They can clean them very easily.

And regarding changes that we might make to these face
shields, we’re always open to more feedback.

And we’ve gotten some feedback that some providers would
like a little bit more length on the bottom of it, so that it kind
of interfaces with their sternum a little bit better, so that it
kind of blocks off any transition into the bottom. And some
providers want a visor over the top. So, on this Prusa
design, you can see that this is open. This is meant to
ventilate air so that it doesn’t fog up, but it does allow some
particulates can get down in there, so, maybe, some visor to
cover that portion up. Those are the two big pieces of
feedback that we’ve gotten that we’re trying to come up with
adaptations for and adjustments. But currently what we’re
trying to do is stick with designs that are recommended by
NIH print exchange. These are the ones that have been
approved for clinical use.
