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

Brass-tipped nozzles are the most common nozzles used for nonabrasive filaments such as ABS, PLA, and nylon. Since they transfer heat quickly, they produce clean prints and are unlikely to clog. However, brass is soft, so it will wear out quickly when used with abrasive materials. Copper-tipped nozzles transfer heat better than brass-tipped nozzles, making them best for PEEK, Ultem PEI, and other materials that require high heat to print. 303 stainless-steel-tipped nozzles don’t contain lead, so choose them when printing parts that may touch skin or food. However, they don’t transfer heat very well, which means they need high printing temperatures and don’t print as quickly as brass- or copper-tipped nozzles.

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.
