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.

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!

Bestimmung des Prozessfensters von SLS-Pulvern mittels DSC

Beim SLS-Verfahren wird das Bauteil schichtweise in einem Pulverbett mit einem Laserstrahl aufgebaut, indem der Strahl über die Oberfläche der Bauteilgeometrie geführt wird, um das Pulver lokal aufzuschmelzen. Um ein Polymerpulver auf seine Eignung für SLS zu charakterisieren und das Prozessfenster zu bestimmen, wird die Dynamische Differenzkalorimetrie (DSC) eingesetzt. Erfahren Sie, wie Sie die Messungen durchführen und welche Schlüsse Sie daraus ziehen können.

How UV-light Exposure Times Affect Component Properties in Additive Manufacturing

Additive Manufacturing (AM) has been around for several years. The main application for a long time was prototyping in the early stages of product development. Recently, new technologies like Digital Light Synthesis (DLS) are shaking up the AM sector. Using DLS and a two-stage dual-curing process, 3D printing is now being considered for mass production of parts since it has become considerably faster and the final product shows improved mechanical characteristics.
