Abstract
Various embodiments may include a powder for processing in an SLS method comprising a blend of a first material and a second material. The first material comprises at least one of an amorphous high temperature-resistant thermoplastic or a liquid-crystalline polymer and the second material comprises a semicrystalline material. The blend exhibits a crystallization melting point.
Claims8
