Social, 3D Printed Cast for Broken Bones

Social, 3D Printed Cast for Broken Bones


This episode of “In The Making”
is brought to you by Ting, mobile to make sense. We’re in Oakland,
California, and I just heard about a 3D printed
medical cast that involves a social media
and an app that you use. We gotta check this out. We’re going into
Fathom here where they’ve taken a
100-year-old brass foundry, and they’ve turned into a
high-tech 3D printing studio. We noticed that there was a lot
of casts being made in the 3D printed community,
and we loved the idea of a medical application
for 3D printing. We have the scanning abilities
to get that close fit to your arm, and the
materials of 3D printing are really good for
medical application. We started off with
the scan of an arm, from that we’re able to create a
surface by wafting curves based on that scan. We had that solid cast, we were
able to unroll that surface, and that’s what it looks
like when you unroll. And then once we had that, we
put down the text on top of it. So we used control points
to pinch and pull things to be denser in this
area that we marked up as the break, the area
that needed more support. Once we rolled it back on,
that’s what it looks like. You would have a page that’s
dedicated to the cast. So you would say, hey, I just
broke my arm, big bummer, but send me a message that
I could put on my new cast. To me the most
interesting technology driving the hash cast
is parametric modeling. Parametric modeling takes
in various parameters, and then helps create a
3D model based on that. In this case there
are three parameters. There’s the actual
dimensions of your arm, which come from a 3D scan,
there’s the information from the doctor, which
largely came from x-rays, and then there’s
the social media, which defines the
text, which will then be wrapped around your arm. The parametric model
for the hash cast takes these three parameters,
combines them together, creates a 3D file, which is
then sent to the 3D printers, and prints out the hash cast. Having broken a bone,
or seven, in my day, I know what a pain casts are. So assuming you get that
itch you just can’t scratch, not only does Hash Cast
have the physical benefits of being lightweight,
removal, and breathable, but it also has an
emotional benefit, providing a constant reminder
that your friends care. Unless they’re like my friends,
who would write something like, you dumb ass. Great news, everybody. We’ve got our first sponsor,

    Okay, I can understand the 3D printing as helpful, but…Tweets as medical help? Really?
    What's next? Advertisements on wheelchairs?

    Cool idea! Very 21st century. Do you know what printing process/material they used? I would think a tiny bit of flex in the material would be necessary in case the arm swells? I guess I wouldn't know though, never broken an arm… 

    Keep up the good work.
