3D Printer Parts and Accessories

3D Printer Extruder Heating Elements

Replace damaged heating elements in your 3D printer, or switch them out to print at a faster speed or higher temperature.

Automatic Leveling Probes for 3D Printers

Trace the ups and downs of your print surface. These probes automatically adjust your printer’s head to be level with the surface—even if the surface isn’t level.

3D Printer Nozzles

Extrude melted filament onto print surfaces to build 3D printed parts.

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.

Protective Covers for 3D Printer
Extruder Heating Elements

Shield your 3D printer's heating element, or hot end, from sticky filament buildup with these nonstick silicone covers. By repelling plastic and keeping the heating block clean, they increase the heating block's life and prevent stuck filament from dripping off and ruining prints.

High-Strength HTD Timing Belt Pulleys

High-Strength Corrosion-Resistant
HTD Timing Belt Pulleys

Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern.

High-Strength HTD Timing Belt Idler Pulleys

Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners to remove slack from timing belts.

DC Equipment-Cooling Fans

Running on 48V DC power or lower, these compact fans fit inside electronics and other small, heat-sensitive equipment to keep things cool.

Raw Materials

Borosilicate Glass Sheets

Also known as Pyrex and Schott glass, borosilicate sheets are heat resistant, clear, and have a super-smooth surface. They're used in a range of applications, from high-temperature viewports to 3D printing.

Electrical-Insulating Ultem PEI Film

Often used for circuit-breaker housings, manifolds, and semiconductor components, Ultem PEI offers excellent electrical-insulating properties.

Clear Slippery High-Temperature FEP Film

The slippery surface on this FEP film prevents sticking. Use it as a release film when making molded parts.
