Material Science in Additive Manufacturing: Crystallization Behavior in Polymer PBF

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.

In our previous episode, Dr. Natalie Rudolph talked about how we can use DSC measurements to determine the process window and understand material behavior during Polymer Powder Bed Fusion (PBF). Today’s focus is on the crystallization behavior of PA12 powder using Differential Scanning Calorimetry (DSC).

This week’s topic: Crystallization Behavior in Polymer PBF

  • Time dependence of crystallization using a semi-crystalline thermoplastics as an example
  • Carrying out crystallization measurements to determine the crystallization kinetics for process simulation
  • The impact of crystallization of Nylon PA12 powder on the print result

Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), is one of the most used Additive Manufacturing technologies to produce structural plastic parts. It does not require molds or support structures. Furthermore, it can produce complex geometries, internal structures and thin walls with mechanical properties comparable to injection-molded parts. This shortens the development cycle and makes it an alternative for many work pieces and even whole assemblies. In this article, we explain the process principle and materials used in the SLS process.
