Often used when printing with carbon-fiber- and glass-filled filaments, these nozzles resist wear from abrasive materials, so they last longer than standard nozzles. They are compatible with fused filament fabrication (FFF) 3D printers. Screw them into your printer’s heating end to install.

When choosing a nozzle, make sure the trade name is compatible with your printer and heating end. You should also consider the nozzle’s material and opening diameter, which will affect the quality of your part.

Hardened steel nozzles resist wear 10 times better than brass nozzles. However, they don’t transfer heat well, so they require higher printing temperatures. Nickel-plated nozzles have a slippery surface, which creates less friction, so filaments flow smoothly. The slippery surface also prevents plastic from sticking to the nozzle.

For opening diameter, consider whether you need precision or speed. The smaller the nozzle opening, the smoother the finish and the finer the detail, making these nozzles best for small and intricate parts. The larger the nozzle opening, the faster they print and less likely they are to clog, which is good for abrasive materials and large, strong parts. The most common opening to balance precision and speed is 0.4 mm.
