Abstract:
Provided is a poly(aryl-ether-ketone) (PAEK) powder suitable for use in a method for building objects layer-by-layer by electromagnetic radiation-generated sintering, which is obtained from a thermal pretreatment at a temperature between 260° C. and 290° C. and which has a melting temperature which is stable, at the build temperature, and below or equal to 330° C.
