Abstract

The present disclosure relates to method of making three-dimensional (3D) objects using an additive manufacturing system wherein the part material comprises a polymeric component comprising at least one poly(ether ether ketone) polymer (PEEK) having a weight average molecular weight (Mw) ranging from 75,000 to 100,000 g/mol (as determined by GPC), for example in the form of filaments or spherical particles, for use in additive manufacturing systems to print 3D objects.
