"Powder aging and degradation"

A Process Control and Interlayer Heating Approach to Reuse Polyamide 12 Powders and Create Parts With Improved Mechanical Properties in Selective Laser Sintering

Capable of building high-quality, complex parts directly from digital models, selective laser sintering (SLS) additive manufacture (AM) is a core method of agile manufacturing. Polyamide 12 is the most commonly and successfully used polymer powders …
