3D Printing: Crystallization Kinetics of Polyamide 12 during Selective Laser Sintering

Powder Bed Fusion (PBF), also called Selective Laser Sintering (SLS), is the layer-by-layer construction technology of 3D objects, where a laser beam selectively traces over a predefined area on the powder layer. One of the most widely used materials is PA12.

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.
