3D Printer Nozzles

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.

Nickel-Plated Brass Tip—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. 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.

Opening Diameter—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.

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.

Hardened Nickel-Plated Steel Tip—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.

Diamond Tip—Diamond-tipped nozzles last longer than any other 3D printing nozzle in our offering, even when using the most abrasive filaments. They also transfer heat the best, improving your printing speed, precision, and layer adhesion.

High-Flow 3D Printer Nozzles

Print up to 60% faster with better layer bonding than standard nozzles. These nozzles have a split core through the body that makes more contact with the filament to melt it quicker than nozzles with a single hole through the body. The tip is brass, which is the most common material used for nonabrasive filaments such as ABS, PLA, and nylon. Brass transfers heat quickly, so these nozzles produce clean prints and are unlikely to clog. However, brass is soft, so it will wear out quickly when used with abrasive materials. A nickel plating makes their surface slippery, creating less friction so filaments flow smoothly and help prevent plastic from sticking to the nozzle.

They 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.

Opening Diameter—You should also consider the nozzle’s opening diameter, which affects precision and 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.

Abrasion-Resistant High-Flow 3D Printer Nozzles

Print at faster rates than standard nozzles using abrasive filaments, such as carbon-fiber- and glass-filled filaments. Instead of a single hole through their body, these nozzles have a split core that makes more contact with your filament, speeding up melting for 60% faster flow and better layer bonding. Their body is copper, which also helps transfer heat to the filament for fast melting. To resist abrasion 10 times better than brass tips, the tip of these nozzles is hardened steel. Nickel plating makes their surface slippery, which creates less friction, so filaments flow smoothly. The slippery surface also prevents plastic from sticking to the nozzle.

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.
