Zusammenfassung:	The present disclosure relates to a method for manufacturing a three-dimensional (3D) object with an additive manufacturing system, comprising a step consisting in printing layers of the three-dimensional object from the part material comprising a polymeric component comprising at least one poly(aryl ether sulfone) (PAES) polymer having a number average molecular weight (Mn) of at least 12,000 g/mol and a polydispersity (PDI) of less than 1.7. The present invention also relates to polymeric filaments comprising such a PAES, as well as to the use of this PAES to prepare filaments and to print 3D objects.
