This work reports the finding that poly(ethylene terephthalate) [PET] powder is a good material for use in selective laser sintering (SLS). SLS of polymer powders is one of the 3D printing or “additive manufacturing” methods. However, the use of SLS for polymers has been stymied by a paucity of suit...
