The hardened steel extruder gear assembly is an internal component of the hardened steel extruder unit. It comprises a driven gear and an active gear that work together to feed filament into the hotend. Built with heavy-duty materials, the hardened steel extruder gear has a better capability of printing with tough engineering filaments like PAHT-CF and PET-CF for long-lasting performance. If abrasion or clogging occurs due to extended use, users can just replace the extruder gear assembly rather than the whole extruder unit. *The P1 Series Extruder Unit comes with stainless steel extruder gear. Users can upgrade it to hardened steel extruder gear for better abrasion resistance to engineering filaments.
