On the Reuse of SLS Polyamide 12 Powder
Materials, 2022 In the Selective Laser Sintering (SLS) technique, the great majority of the powder involved is not included in the final printed parts, being just used as a support material. However, the quality of this powder is negatively affected during the process since it is subjected to high temperatures (close to its melting temperature) during a long time, i.e.

New powder reuse schema in laser-based powder bed fusion of polymers.
Waste ManagementThe laser-based powder bed fusion of polymers (PBF-LB/P) process often utilizes a blend of powders with varying degrees of degradation. Specifically, for polyamide 12, the traditional reuse schema involves mixing post-processed powder with virgin powder ...

Revealing the Effects of Powder Reuse for Selective Laser Melting by Powder Characterization [PDF]
JOM, 2019 In a selective laser melting process, it is common to reuse the powder in consecutive cycles of the route because it is more sustainable and cost effective. However, it is unknown whether reusing the material has an influence on the process.
