Removable Nozzle Hotend Assembly 0.4mm for Bambu Lab P1P / P1S / X1 / X1C

The Removable Nozzle Hotend Assembly 0.4mm is an essential engineering upgrade tailored specifically for Bambu Lab CoreXY 3D printers, including the Bambu Lab P1P, P1S, X1, and X1-Carbon (X1C). Designed to solve the ongoing frustration and cost of disposable factory hotends, this assembly features a modular, removable screw-in nozzle design.

Designed for Heavy-Duty High-Speed Printing

Stock Bambu Lab P1/X1 hotends are built as a single sealed piece. If the nozzle tip suffers from internal abrasion, severe clogs, or wear, you must discard the entire hotend assembly and purchase a new one. With this upgraded P2S Removable Nozzle Hotend, you retain the precision CNC-machined aluminium heatsink and copper heater block, swapping only the threaded nozzle tip whenever needed.

Key Features & Engineering Highlights

• Economical Modular Architecture: Replace just the 0.4mm nozzle tip in seconds, lowering maintenance downtime and spare parts expenditure.
• All-Metal Thermal Architecture: Capable of continuous operation up to 300°C (and high-temp setups up to 500°C with upgraded thermistors/heaters).
• Precision Polished Bimetal Heatbreak: Low-roughness internal bore (Ra < 0.4) guarantees frictionless filament feeding and prevents heat creep during high-retraction prints.
• Plated Copper Heater Block: Provides rapid thermal conductivity and uniform heat saturation across the melt zone at print speeds up to 500 mm/s.
• Standard Bambu Heater & Thermistor Mounts: Machined with exact retention slots for the stock ceramic heating element, thermistor cartridge, and retaining clip.

Installation Guide

1. Power down the printer and disconnect the toolhead cables.
2. Carefully remove the silicone sock, ceramic heating pad, and thermistor sensor from your original hotend.
3. Transfer the heater pad and thermistor into the precision slots of the new Removable Hotend Assembly and secure the retaining spring clip.
4. Mount the hotend into the toolhead bracket using the two mounting screws.
5. Reconnect the toolhead wiring, perform a PID autotune if necessary, and resume printing.
