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.

Influence of the Surface Modification of Calcium Carbonate on Polyamide 12 Composites. [PDF]
Polymers (Basel), 2020 In previous investigations, it was found that the thermal properties of a polyamide 12 compound can be manipulated, using a designed filler, to improve the melting as well as crystallization behavior, determined for selective laser sintering. A common downside of the introduction of a non-flexing mineral filler is the reduction of the mechanical ...

Polyamide 12 Filled with Cross-Linked Polyethylene Waste: Processing, Compatibilization, and Properties [PDF]
Materials Research, 2023 Cross-linked polyethylene (XLPE) is primarily used as a coating and insulator for electrical wires and cables. The cross-links render recycling through remelting unfeasible, and XLPE waste is usually incinerated or sent to landfills.
