For biocompatible prosthetics, from dental implants up to bone parts, manufacturers have to find the best way to correlate process parameters and the material properties as to meet the unique needs of individuals.
Additive manufacturing techniques aim at creating complex biocompatible structures able to overcome the present shortfalls of the metal and metal alloys implants related to cytotoxicity, corrosion or stress shielding effects. Direct Metal Laser Sintering was considered for studying the influence of thermal stress during the layer-by-layer sintering process of metal alloy powder and on the thermally induced warping of the dried layers.
