Variations of Powder Bed Fusion: Material Science in Additive Manufacturing

NETZSCH_Week 3.2_Additive Manufacturing

Powder Bed Fusion (PBF) is one of the oldest Additive Manufacturing technologies invented in the 80s. However, its suitability for end-use parts and its constant innovations are driving this technology further ahead. This week we look at two important variations of Powder Bed Fusion.

Smart Thermal Analysis: Measurements Wanted?

Imagine the typical situation in everyday laboratory work: A new sample has to be analyzed, but what are the suitable measurement conditions such as temperature program, sample mass or the right crucible? And what measurement results can be expected? Perhaps such kind of sample was already measured by you in the past ‒ or maybe by NETZSCH. Wouldn’t it help a lot to simply search in a database for thermal analysis? Identify, which is a part of the Proteus® analysis software, is the solution!

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!
