On the Reuse of SLS Polyamide 12 Powder. [PDF]
Materials (Basel), 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.
