Filament in PEI 9085 1.75 mm natural 2 kg

PEI, that is polyetherimide, is a high performance plastic that takes high heat. This is the material on a roll as a filament for 3D printers, with a wire diameter of 1.75 mm. The material is amorphous, which means it has no melting point but softens gradually, and it takes 170 degrees in continuous service. It burns slowly and goes out by itself, rated UL 94 V-0 without a flame retardant additive, which is the very reason to choose PEI over more common printing plastics.

This grade is PEI 9085, developed for demanding printed parts. Beyond aircraft interiors it is also approved for rail interiors, that is to say the sharp fire and smoke requirements for trains. That makes it the choice when a printed part is to sit in a vehicle or an aircraft and still meet the fire requirements.

This version is supplied in natural color on a larger roll of 2 kg, for longer prints without a change of filament.
