LASER SINTERING POWDER MADE OF POLYOXYMETHYLENE, METHOD FOR THE PRODUCTION THEREOF, AND MOLDED PARTS MANUFACTURED USING SAID LASER SINTERING POWDER

摘要

The invention relates to a polyoxymethylene (POM) powder for use in a selective laser sintering process and having the following parameters: Isothermal crystallization time (at 152° C.) >3 min Mn from 22 000 to 25 000 g/mol Mw from 60 000 to 140 000 g/mol Mw/Mn from 3 to 5 MVR from 15 to 70 [cm3/10 min] d50 average particle size 60 μm Particle size from 30 to 130 μm. A process for producing the powder, and also moldings produced from this powder by a selective laser sintering process, are also described.
