Industry Portion

3D Printed Cast

Broken Bone

We haven’t advanced the way to heal broken bones in over 50 years

Broken Bone

The fiberglass and plaster casts

3D printing has many applications, in manufacturing, medicine, architecture…

Broken Bone

The process straightforward

Broken Bone

First, a scanner is used to measure and analyza the shape of the broken limb

Design 3D

Design the shape of the broken limb in Solidworks software!

The cast blueprint is then 3D printed in multiple pieces so it can be applied to the patient , where it will stay until the bone is healed

And there are so many benefits to this modern cast over the outdated plaster ones For instance, the 3D-printed casts are just as protective and durable as the ones we use today

Broken Bone

They’re also waterproof, and they’re insanely more comfortable

Broken Bone

Having that open lattice structure also enables doctors to start to introduce companion treatments, like ultrasound

Broken Bone

Which can stimulate the injured area and lead to quicker recoveries

Broken Bone

While 3D- printed casts have yet to hit the market, many of the companies looking to capitalize on them are starting to test their casts in clinical trials, and that menans on real people

Broken Bone

So for now, it looks like the only remaining hurdle for using them is their price, as many of the cast designs cost anywhere from $200 to $500 of more

Broken Bone

Even though this technology won’t make breaking a bone suck and less , it just may make healing it a lot better
