Product description

Q1: Which Bambu Lab printer models can this extruder assembly fit?

A: It is specially designed for Bambu Lab P2S, matches original mounting dimensions perfectly, no trimming or modification needed for direct replacement.

Q2: What upgrades does the stainless steel structure bring compared to the stock plastic one?

A: Stainless steel gears deliver stronger wear resistance, higher extrusion force, less filament slipping, and works long-term with abrasive carbon fiber/wood-filled filaments without tooth abrasion.

Q3: Does this assembly retain the original filament detection function after installation?

A: Yes, all original detection sensors and wiring positions are fully reserved. Filament breakage and runout alerts work normally after correct installation.

Q4: What printing failures can this replacement kit solve effectively?

A: It fixes common troubles like under-extrusion, clicking extruder noise, uneven layer lines, frequent feeding skips and intermittent print defects caused by worn original gears.

Q5: Are all necessary small accessories included in the package? Do I need to buy extra spare parts?

A: Complete assembly with matched bearings, springs, fastening screws and gaskets is included. You can finish replacement directly following official online tutorials without purchasing extra hardware.
