USE OF POLYARYLENE EHTER KETONE POWDER IN A THREE-DIMENSIONAL POWDER-BASED MOLDLESS PRODUCTION PROCESS, AND MOLDINGS PRODUCED THEREFROM

摘要

The present invention relates to a powder comprising polyarylene ether ketone (PAEK), to the use of this powder in processes whose operation is based on pulverulent materials and in which the desired structures are produced layer-by-layer via selective melting and hardening, and also to moldings produced from this powder by this process. The moldings constructed using the powder by the process, when compared with moldings produced by conventional laser-sintering processes, exhibit marked advantages in relation to their heat resistance and their mechanical properties. This can open up new applications by means of rapid prototyping/rapid manufacturing (RP/RM) processes, for example in the engine compartment of a car.
