LASER-SINTERING POWDER COMPRISING PMMI, PMMA, AND/OR PMMI-PMMA COPOLYMERS, A PROCESS FOR PREPARING THEREOF AND MOLDINGS PRODUCED FROM THE LASER-SINTERING POWDER

摘要

PURPOSE: Provided are a laser-sintering powder capable of giving better dimensional stability and surface quality in the parts produced by means of selective laser-sintering, a process for preparing the laser-sintering powder, and moldings produced from the laser-sintering powder. CONSTITUTION: The laser-sintering powder comprises at least one polyamide and at least one poly(N-methylmethacrylimide) (PMMI), one polymethyl methacrylate (PMMA), and/or one PMMI-PMMA copolymer.
