Material Science in Additive Manufacturing: Our Advanced Series!

NETZSCH Additive Manufacturing Science

In 2020, we started our “Material Science in Additive Manufacturing” video series as we faced an increasing interest from the industry to perfect their 3D printing processes and outcomes. First, we focused on understanding the 7 different Additive Manufacturing (AM) technologies. In the advanced section, we will dive deeper and look at the underlying material science as well as the methods suitable to analyze the materials and to optimize processes

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


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.

How to Determine the Process Window for SLS Powders Using DSC

Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), the component is built up in layers in a powder bed using a laser beam that passes over the cross-section of the layer to locally melt the powder. In order to characterize a polymer powder for its suitability for SLS and to determine the possible process window, Differential Scanning Calorimetry (DSC) is used. Learn how to set up and interpret the measurements!
