Material Science in Additive Manufacturing: Melt Rheology in PBF Using Rotational Rheometry

In Powder bed fusion there is no flow and no shear rate. For powder coalescence, the local molecular motions and entanglements across the layers are important. So today, Dr. Natalie Rudolph will be focusing on the rotational rheometry.

Working Principle of Capillary Rheometers

NETZSCH_Rosand_Capillar Rheometer

Traditionally, capillary rheometers have been used to measure the shear viscosity and elasticity of viscous materials at high shear rates. In this article and video, Natalie Rudolph (PhD) explains the working principle, parameters and their relations of the capillary rheometer.
