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.

Static-Dissipative High-Temperature 3D Printer Filaments
Not only do parts printed from these filaments protect sensitive electronics, but they also hold their shape in temperatures that would deform or degrade most plastic. Use them to make parts for hot environments, such as engines, ovens, or lighting equipment. These filaments combine heat-tolerant plastic with a static-dissipative material that keeps static from building up and prevents shocks.
Use these filaments with a fused filament fabrication (FFF) 3D printer. They require an all-metal extruder to reach the recommended printing temperatures, and should be printed onto a heated bed to keep parts from warping as they cool.
PEI filaments have electrical-insulating properties, which make them good for printing circuit-breaker housings and semiconductor components.
Use an electrical resistance tester to make sure printed parts meet proper resistivity levels. In general, the target surface resistivity for PVDF is 106 to 109 ohms, and for PEI and PEKK it's 106 to 107 ohms. To adjust your measurements, change the temperature of your printer's extruder. As the extruder's temperature increases, so will the printed part's resistivity.
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.

Print Surfaces for 3D Printers
Also known as build sheets, these print surfaces adhere to the printer beds of fused filament fabrication (FFF) printers to create a build surface for all types of filaments. More durable than masking tape, easier to take off than glue, and better than printing on a bare bed, they grip the first layer of your printed part and firmly hold it in place during the print to prevent warping. Once cooled, you can easily remove the part from the print surface without damaging the part or the surface. You can also remove the print surface from the printer bed without leaving a sticky residue behind, making surface changes quick and easy.
All are heat resistant and durable, so they can be used multiple times. Use them to protect your printer beds from cracking due to rapidly changing temperatures—it’s cheaper and easier to replace a print surface than a printer bed. Cut the print surfaces to size with scissors, peel off the backing, and stick them in place.
PEI print surfaces are the longest lasting print surfaces. They are also the easiest to release, making them good for sticky filaments like PETG. They have a smooth texture, which will leave a smooth finish on the bottom of your part. Use them on both heated and unheated printer beds.
Use the primer and smoothing tools to remove wrinkles and trapped air bubbles that can occur when applying large print surfaces.
