Thermo‐Optical Analysis of Surface‐ and Volume‐Additivated Polymer Powders for Near‐Infrared Laser Powder Bed Fusion

Advanced Photonics Research, EarlyView.
Precipitated PA11 powders for laser powder bed fusion are additivated with small amounts of carbon black nanoparticles on and in the particles. The position of the nanoparticles has a strong impact on dispersion, crystallization, and thermal oxidation.

Unravel melt pool and bubble dynamics during laser powder bed fusion of polyamides using synchrotron X-ray imaging and process simulation

Virtual and Physical Prototyping
Laser powder bed fusion (LPBF) of Polyamide 12 (PA12) using a near-infra-red (NIR) beam is largely unexplored; therefore, the beam-matter interaction, evolution mechanisms of the melt pool and defects remain unclear. Here, we employed a combination of in
