Abstract
Waste product from any of a variety of processes (injection molding, selective laser sintering) is processed to form powders that have particle size and distribution optimal for a 3D printing technology known as Composite Based Additive Manufacturing (CBAM). Alternative recycling processes include grinding and sieving, emulsion extruding, and liquid-liquid phase separation.
