Abstract
The use of Additive Manufacturing methods in the manufacture of custom implants and the development of new biocompatible materials that can be processed by Selective Laser Sintering Technology, represent a trend in biomechanics. In this study two types of biomaterials were analysed and tested – PA 2200, the most used material for cranioplasty, obtained at different laser powers and polymethyl-methacrylate (PMMA). In order to analyse the mechanical behavior of the evaluated materials, the mechanical tests were made for tension, flexure and compression. It was found that the values for PA 2200 material are within the limits of the mechanical characteristics required for cranioplasty implants.
