Multimetal Research in Powder Bed Fusion: A Review
Materials, 2023 This article discusses the different forms of powder bed fusion (PBF) techniques, namely laser powder bed fusion (LPBF), electron beam powder bed fusion (EB-PBF) and large-area pulsed laser powder bed fusion (L-APBF). The challenges faced in multimetal additive manufacturing, including material compatibility, porosity, cracks, loss of alloying elements

Understanding the Reusability of Ti6Al4V Powder in Laser Powder Bed Fusion. [PDF]
Eng Sci Addit ManufThis 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.

Laser Powder Bed Fusion of Metal Coated Copper Powders
Materials, 2020 Laser powder bed fusion (L-PBF) of copper alloys with high copper content is difficult due to the high infrared reflectivity and thermal conductivity of these alloys. In this study a simple and scalable method for coating copper powder with tin and nickel is presented, and suggested as an alloying strategy for such alloys.

Continuous reuse of polyamide 12 in powder bed fusion. [PDF]
Sci RepAbstract 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 ...
