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.

Improved Mechanical Properties of Compatibilized Polypropylene/Polyamide-12 Blends [PDF]
International Journal of Polymer Science, 2015 Compatibilized blends of polypropylene (PP) and polyamide-12 (PA12) as a second component were obtained by direct injection molding having first added 20% maleic anhydride-modified copolymer (PP-g-MA) to the PP, which produced partially grafted PP (gPP).
