When it Comes to Bionic Arms, Durability Matters

A bionic arm supporting weight

There’s a difficult needle to thread when it comes to bionic arm durability. Prosthetic limbs need to survive everything your daily life throws at them, while also being lightweight enough to wear for long periods of time. That’s why the materials a prosthesis is made out of matter so much. It’s difficult to create a prosthesis that is lightweight. It’s also difficult to create a prosthesis that is durable. But to create a bionic arm that checks both boxes? That’s a real challenge.

With the introduction of TrueLimb, we’ve met the challenge. 

We produce TrueLimb using a 3D printing process known as multi-jet fusion. All 3D printing allows for the creation of one-of-a-kind objects, but most of them aren’t very strong. Multi-jet fusion is different. It’s how we can make TrueLimb such a lightweight, durable prosthesis. In a previous post, we discussed all the methods of 3D printing currently in use, and explained what makes multi-jet fusion so ideal for prosthetic devices. Now, we’re ready to show you the tests we put TrueLimb through to make sure it’s as strong as you need it to be.

In this video, you can see all the bionic arm durability tests we put TrueLimb through to make sure it’s incredibly strong. We dropped it, sanded it, took a lighter to it, and lots more. However, we don’t expect you to submit your TrueLimb to the level of abuse we put this one through. We simply want to demonstrate that you don’t have to be precious with it. TrueLimb isn’t like a smartphone, where one false move results in a shattered screen and an expensive repair. You can wear TrueLimb with confidence, and use it like you would any other body part. You can live your daily life without treating TrueLimb like a fragile piece of technology — you can treat it like an extension of yourself.
