Powder Surface Roughness as Proxy for Bed Density in Powder Bed Fusion of Polymers [PDF]
Polymers, 2021 Powder bed fusion of polymers is becoming increasingly adopted by a variety of industries to tailor the strength, weight and functionality of end-use products. To meet the high standards of the modern manufacturing industry, parts built with powder bed fusion require consistent properties and to be free of defects, which is intrinsically connected to ...

Understanding the reusability of Ti6Al4V powder in laser powder bed fusion [PDF]
Engineering Science in Additive ManufacturingThis 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.

Continuous reuse of polyamide 12 in powder bed fusion [PDF]
Scientific ReportsAbstract 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 ...
