Seeing the Big Picture: Improving The Prosthetic Design Cycle Using 360°
3D Digital Image Correlation
Abstract
Additive manufacturing is one of the most promising emerging
technologies for building prosthetic sockets. However, there is no
reliable way to estimate the factor of safety and the lifetime of 3D
printed prosthetic sockets. Here, we explore 360° 3D digital image
correlation (DIC) and discover how this new tool can increase our
understanding of prosthetic structural failures. We establish that this
new technology can dramatically improve the prosthetic design cycle by
identifying local strain concentrations and by highlighting limitations
in current simulated models. Overall, 360° 3D DIC technology empowers
prosthetic engineers to characterize the performance of new materials
and create innovative designs that are both safe and affordable.
