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.

How Fillers Increase Isotropic or Anisotropic Behavior of SLS Parts through Their Alignment

In general, the addition of fillers leads to an increase in mechanical performance. While a critical length of the fillers is needed to have an effect on the strength of components, the stiffness is already increased with fillers with small aspect ratios. To understand how the stiffness or modulus change as a function of the filler geometry and filler content, Dynamic Mechanical Analysis (DMA) can be used. Learn more in our article!
