Abstract
The present disclosure relates to an additive manufacturing (AM) method for making a three-dimensional (3D) object, comprising a) depositing successive layers of a powdered material (M), at least partially recycled, comprising at least one poly(ether ketone ketone) (PEKK), having a phosphorus content of more than 30 ppm, as measured by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), and b) selectively sintering each layer prior to deposition of the subsequent layer.
