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.

As you consider material, keep in mind its ability to transfer heat and resist wear. The quicker the nozzle transfers heat to the filament, the smoother it prints. The better it resists wear, the less likely it will dull and break down from abrasive filaments, such as those made with glass and carbon fiber. Brass nozzles are the most common nozzles used for nonabrasive filaments such as ABS, PLS, 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. Nickel-coated brass nozzles have a coating that protects them from abrasive filaments for a longer life than unfinished brass. Nickel-plated copper nozzles transfer heat better than brass nozzles, making them best for PEEK, Ultem PEI, and other materials that require high heat to print. Their nickel plating lets filaments flow smoothly—even sticky ones like TPU and PETG. Stainless steel nozzles don’t contain lead, so choose them when printing parts that may touch skin or food. While they don’t print as fast as brass nozzles, they stand up better to abrasive filaments. Hardened steel nozzles resist wear 10 times better than brass and can be used regularly with carbon fiber-filled filaments and other abrasive materials. But, they don’t transfer heat very well, which means they require high printing temperatures and don’t print smoothly.

For opening diameter, consider whether you need precision or speed. The smaller the nozzle opening, the smoother the finish and 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 clog, which is good for abrasive materials and large, strong parts. The standard opening for nonabrasive filaments is 0.4 mm; the standard for abrasive filaments is 0.5 mm.
