Estimating Residual Stresses in SLS Parts Using DMA

SLS Residual Stress DMA NETZSCH

Selective Laser Sintering (SLS) is one of the most used Additive Manufacturing technologies to produce structural plastic parts. When operated at elevated temperature, any residual stresses could be detrimental for the part performance. In order to better understand residual stresses, knowledge of a material’s modulus is needed. Learn more about residual stress and how to measure the material property using a thermal analysis method.

Estimating Warpage of Selective Laser Sintering Parts Using Thermomechanical Analysis

Warpage SLS TMA NETZSCH

The plastics used in Selective Laser Sintering (SLS) have a higher thermal expansion when compared with other materials. Therefore, it is important to know how the dimensions of an SLS part change at different temperatures during the build and during use. The higher the thermal expansion coefficient, the more prone are the parts to warpage or curling and the build-up of residual stresses. Learn more!
