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.

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.
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.

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.
PEKK filaments can be printed at a lower temperature than PEEK and produce parts that withstand more heat. Parts printed with PEKK must be annealed to reach their full strength and heat resistance.
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.
Annealing is the process of heating prints to a specific annealing temperature and then slowly allowing them to cool. This makes the finished print harder, stronger, and more heat tolerant. Maximum temperature after annealing replaces the maximum exposure temperature once this process has been completed.
