Virtually eliminate 3D printer nozzle wear with a Micro Swiss M2 High Speed Steel nozzle!


Standard brass nozzles used in 3D printers are made of fairly soft metal and over time the nozzle's orifice will wear away to an uneven shape and larger diameter causing poor print quality. 3D printer filaments containing abrasive materials such as wood fibers, carbon fiber, metal powder, and glow-in-the-dark powders can accelerate this process very quickly. Accidentally crashing a nozzle into the printer's build surface or retaining clips can also severely damage standard brass nozzles as well.

The Micro Swiss M2 Steel nozzles are designed for high temperatures, abrasion resistance, and with superior non-stick properties. The nozzles are machined from M2 high speed steel, hardened, and tempered to 68 HRC. They are then plated with Electroless Nickel Plating, and coated with WS2 coating.

The M2 nozzle can safely operate up to 450C without the steel losing its hardness and features a manufacturer's limited lifetime warranty against wear!

(Note: Many manufacturers of composite 3D printing filaments which contain abrasive materials recommend nozzle orifices 0f 0.5mm or larger to  greatly reduce the likelihood of nozzle clogging. If you are unsure what size is right for you, please check with the filament manufacturer for their recommendation

Due to steel having a lower thermal conductivity than brass, you may need to increase your nozzle temperatures when printing by approximately 5°C or more when using a steel nozzle.)
