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.
Today’s focus is on the crystallization behavior in Polymer Powder Bed Fusion using Differential Scanning Calorimetry (DSC). Find out more about the time dependence of crystallization with the example of a semi-crystalline thermoplastic and learn about isothermal crystallization of Nylon PA12 powder.
Due to the still limited number of available materials for the Selective Laser Sintering process, there is a constant demand for materials with different properties. The addition of any filler to SLS powder typically has an effect on the processing behavior. Today, we investigate the crystallization behavior of PA12 powder filled with copper spheres and flakes.
In a previous article, the process window in the Selective Laser Sintering process with polyamide 12 powder was determined with dynamic measurements. In this article, we explain how isothermal measurements can be used for more advanced studies.
