ThermaX™ PES (PESU) 3D Printing Filament

Polyether Sulfone (PES or PESU) is a high-temperature aromatic sulfone polymer that exhibits exceptional thermal, mechanical, and chemical resistance properties. PES is part of the PAES (Poly Aryl Ether Sulfone) family of polymers, which includes PSU, PES, and PPSU. ThermaX™ PES is an amorphous polymer and has excellent dimensional stability and creep resistance.

PES has higher temperature resistance and toughness than Ultem™ 1010, offering the ability to print parts with higher mechanical properties at elevated temperature.
