Aging of PA12 Powder in Powder Bed Fusion
Powder Bed Fusion (PBF) is a popular additive manufacturing technology due to its high build resolution and ability to produce microscale geometries without the use of additional support. Despite the many benefits of PBF, there are still some limitations

Understanding the Reusability of Ti6Al4V Powder in Laser Powder Bed Fusion. [PDF]
This study aimed to determine the effects of how powder degrades in quality from use in the laser powder bed fusion process and investigate what changes in the powder cause defects in finished parts. It was determined that the reused powder affected the finished part quality, resulting in an increased number of lack-of-fusion pores.

Powder bed fusion on single lines of Cu-doped hydroxyapatite powder bed
This study aims to design ceramic scaffolds for precise bone reconstruction using Powder Bed Laser Sintering (PBLS) to create cohesive Cu-doped HAp ribbons from a single lasered line on a thin powder bed atop a silicate lime substrate. Depending on laser

Continuous reuse of polyamide 12 in powder bed fusion. [PDF]
Abstract The thermal degradation of polymers in powder bed fusion (PBF, additive manufacturing) is one of the major issues preventing wider adoption of this technology at the production scale. Although standard PBF allows for elastic production of complex parts in a single-step manufacturing process, it is materially inefficient – only ...
