POLY–(ARYL–ETHER–KETONE) (PAEK) COMPOSITION WITH A LOW CONTENT OF VOLATILE COMPOUNDS AND USE OF SAME IN A SINTERING METHOD

摘要

The invention relates to a Poly(aryl-ether-ketone) (PAEK) composition, useful in a process for building a three-dimensional object layer by layer by electromagnetic radiation-generated sintering, said composition being characterized in that it has an aromatic ether content comprised between 0 and 0.4% by mass and an aluminium mass content lower than 1000 ppm, preferably lower than 600 ppm and more preferably lower than 500 ppm.
