Poly-(aryl-ether-ketone) (PAEK) compositions with low content of volatile compounds and their use in sintering methods

摘要

The present invention is a poly(aryl-ether-ketone) (PAEK) composition useful for a method of constructing a three-dimensional object layer by layer by electromagnetic radiation-generated sintering, having an aromatic ether content of 0 to 0.4 mass% and an aluminum mass content of A poly(aryl-ether-ketone) (PAEK) composition, characterized in that it is less than 1000 ppm, preferably less than 600 ppm and more preferably less than 500 ppm.
