The Direct Metal Laser Sintering (DMLS) manufacturing technique induces thermal stresses in parts. When such parts are used at elevated temperatures, residual stresses are relaxed and the part can suffer significant distortion. This study presents values of geometrical distortion for two laser exposure strategies and for different heat treatment temperatures and durations, Surface and bulk hardness data are provided as well as porosity measurements. At temperatures above 300 degrees C, the geometrical changes become important. A stabilization treatment at 600 degrees C can help reduce distortions.
