Hardened steel nozzles are good utility nozzles, suitable for abrasive filaments such as wood fills, glitter fills and metal fills. Even glow-in-the-dark filaments will abrade brass so our Hardened Steel nozzles are a great, lower-cost option when you can’t stretch to a Nozzle X. Rated to a maximum temperature of 500°C. Please note this nozzle is not suitable for printing abrasive filaments at temperatures above 350°C.
