MK8 Plated A2 Tool Steel Wear Resistant Nozzle (CR10 / Ender / Tornado / MakerBot) -1.75mm Filament

Virtually eliminate 3D printer nozzle wear with a Micro Swiss A2 Hardened Tool 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 A2 Tool Steel nozzles are designed for high temperatures, abrasion resistance, and with superior non-stick properties. The nozzles are machined from A2 tool steel, hardened, and tempered to 57-62 RC. They are then plated with TwinClad XT coating. This additional coating has a hardness rating of 65-67 HRC, and includes Non-stick additives giving the surface a very low coefficient of friction (0.08).

Need an even more wear resistant nozzle? Check out the M2 Hardened High Speed Steel version of this nozzle (The most wear resistant steel nozzle Micro Swiss makes).

(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.)
