Additive manufacturing for health technology applications

Abstract

In this study we demonstrate an overview about possibilities in using additive manufacturing for tissue engineering and orthopedic prosthesis. We show the possibilities to produce scaffolds by using a low cost commercial stereolithography system under the use of biocompatible hydrogels like Poly(ethylene glycol) diacrylate. We also demonstrate that it is possible to use a low cost selective laser sintering system to produce individual prostheses to support the healing process in many orthopedic issues.

It is determined that the amount of liquid resin for exploring the specimens should be between 3 to 5 ml.…”
