FFF Machine Parts | McMaster-Carr

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.

Heaters for 3D Printer Beds

For accurate printing, these heaters help the bottom layer of parts stick to the print surface of your 3D printer without shifting. They also prevent parts from warping—these heaters are recommended when printing most kinds of plastic.

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.

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.

Low-Voltage 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.

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.
