Process control of surface quality and part microstructure in selective laser sintering involving highly degraded polyamide 12 materials

Process control of surface quality and part microstructure in selective laser sintering involving highly degraded polyamide 12 materials

Polyamide 12 is one of the most extensively used semi-crystalline polymer materials to date in selective laser sintering (SLS) additive manufacturing, or SLS 3D printing. In this powder-based direct digital manufacturing process, a substantial amount of expensive materials remains un-sintered, recyc...
