ThermaX PEI 1010 3DXTECH produces this 3D printing filament using a specialty compound custom-formulated using ULTEM 1010 PEI resin and advanced carbon additives. PEI is an amorphous, high-performance polymer that combines excellent mechanical, thermal, and chemical resistance properties.Our PEI based filaments offer the ability to create parts with excellent properties at elevated temperatures due to a very high glass transition temperature (Tg). Ideal for use in critical applications which require electrostatic discharge (ESD) protection, a high level of cleanliness, and the outstanding thermal and chemical properties you’ve come to expect with PEI based compounds. MADE IN THE USA We manufacture all of our filaments in our 68,000 ft² manufacturing facility (located in Grand Rapids, Michigan) using state-of-the-art equipment and processes. Our goal continues to be to make the most innovative filaments on the market – targeting difficult end-use applications.
