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!

Metal Additive Manufacturing and the Need for Reliable Thermophysical Property Data

Additive Manufacturing (AM) encompasses a variety of technologies suitable for producing components from liquid, solid or powder feedstocks. Selective Laser Melting (SLM), a powder-bed fusion process, has become a commonly used AM process for rapid prototyping and component manufacturing using metals, alloys and, to a lesser extent, ceramics. Learn more about SLM, suitable materials and how to optimize input parameters for improved product quality using Thermal Analysis.
