PAEK powder, in particular for the use in a method for a layer-wise manufacturing of a three-dimensional object, as well as method for producing it

摘要

By a temper treatment a polyaryletherketone powder is processed such that it is particularly suited for the use in a method for a layer-wise manufacturing of a three-dimensional object. To this effect the powder is tempered at a temperature that is at least 20° C. above the glass transition temperature for at least 30 minutes before it is used as building material.
