Zusammenfassung:The present disclosure relates to an additive manufacturing (AM) method for making a three-dimensional (3D) object, comprising a) the provision of providing a powdered polymer material (M) comprising at least one poly(ether ether ketone) (PEEK) polymer, and at least one poly(aryl ether sulfone) (PAES) polymer, b) the deposition of successive layers of the powdered polymer material; and c) the selective sintering of each layer prior to the deposition of the subsequent layer, wherein the powdered polymer material (M) is heated before step c) to a temperature Tp (° C.): Tp
