High-Temperature 3D Printer Filaments

Parts made with these filaments remain strong and rigid in temperatures that would soften most plastics. They are a lightweight alternative to machined metal parts. Use with a fused filament fabrication (FFF) 3D printer to make parts that will be used near ovens, engines, and other hot machinery. These filaments require an all-metal extruder to reach the recommended printing temperatures. Print parts onto a heated bed to keep them from warping as they cool.

PEI filaments have electrical-insulating properties, which make them good for printing circuit-breaker housings and semiconductor components.

Tensile strength is the best measure of a filament's overall strength. Similar to the stress applied on a rope during a game of tug-of-war, it's the amount of pulling force a material can handle before breaking. A higher rating means a stronger filament. A tensile strength of 5,000 psi and above is considered good; 12,000 psi and above is excellent.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.
