Abstract
A method of making a shaped article comprising printing layers of a polymer composition comprising at least one PEEK-PEmEK copolymer having RPEEK and RPEmEK repeat units in a molar ratio RPEEK/RPEmEK ranging from 95/5 to 45/55, the polymer composition optionally including at least one reinforcing filler, at least one additive, or a combination thereof, and shaped articles obtained from the method. Also described are methods of making the PEEK-PEmEK copolymer and methods of making the polymer composition.
