Powder bed fusion (PBF) is an additive manufacturing technique capable of fabricating highly complex, individualised, and lightweight polymer components. However, to maximise the potential PBF, in terms both economic efficiency environmental sustainability, a successful powder re-use strategy essential. During build, ageing degradation processes affect re-usability un-sintered powder, so used usually refreshed with virgin material before re-use. This study considers effectiveness using 70:30...
Powder bed fusion (PBF) is an additive manufacturing (AM) technique which offers efficient part-production, light-weighting, and the ability to create complex geometries. However, during a build cycle, multiple aging degradation processes occur may affect reusability of Polyamide 12 (PA-12) powder. Limited understanding these phenomena can result in discarding re-usable powder unnecessarily, or production parts with insufficient properties, both lead significant amounts waste. This paper...
Polymer powder bed fusion (PBF) is becoming increasingly popular for the fabrication of lightweight, high-performance parts, particularly medical and aerospace applications. This study investigates effect re-use material aging on coalescence behaviour, melt flowability, isothermal crystallisation kinetics polyamide-12 (PA-12) powder. With increased re-use, a progressive reduction in flowability observed; at 200 °C, particle consolidation time increases from 15 s virgin to 180 recovered build...
