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.

Print Surfaces for 3D Printers
Also known as build sheets, stick these sheets to your printer bed for more accurate 3D printed parts than those made on bare printer beds, masking tape, and glue. They won’t transfer heat between your part and printer bed, which means they grip your part as it prints to keep it from shifting. Then they easily release the part without damaging it once it’s cooled. Because they’re insulating, they also protect glass printer beds from cracking due to sudden temperature changes, so you won’t need to replace the bed as often. You can reuse these sheets multiple times, since they’re durable and stand up to heat.
Use these sheets with fused filament fabrication (FFF) 3D printers. Cut them to size with scissors before sticking them to your printer bed. For large print surfaces, use primer and smoothing tools (both sold separately) to remove wrinkles and trapped air bubbles.
PEI print surfaces don’t grip as tightly as plastic-blend print surfaces, making them easier for removing sticky filaments, such as PETG. They also last longer. Their smooth exterior leaves a smooth finish on the bottom of your part.
