Bambu Lab Hotend with 0.4mm hardened steel nozzle - P1 series

Bambu Lab P1 Series Hotend with 0.4 mm Hardened Steel Nozzle

The Bambu Lab P1 Series Hotend with a 0.4 mm hardened steel nozzle is designed for users of Bambu Lab P1P and P1S printers who require reliable performance when printing a wide range of materials, including abrasive filaments containing carbon or glass fibres. Thanks to its all-metal construction and integrated hardened nozzle, the hotend is resistant to wear and enables long-term operation without loss of accuracy or print quality. The all-in-one design minimises the risk of leaks and ensures fast heating as well as easy replacement of the entire hotend.

Optimised for abrasive and standard filaments

This hotend is ideal for printing standard materials such as PLA, PETG, TPU, ABS, ASA, PC, PA, as well as filled filaments (e.g. PLA-CF, PETG-CF, PAHT-CF). Hardened steel significantly extends the nozzle’s lifespan when printing abrasive blends and ensures consistent print quality even during long-term use. The 0.4 mm nozzle diameter is a universal choice for both detailed and fast printing of standard and technical parts.

Key features

• Hardened steel 0.4 mm – high wear resistance and long lifespan even when printing abrasive filaments

Who is this hotend for?

The Bambu Lab P1 Series Hotend with 0.4 mm hardened steel nozzle is intended for users who frequently print with filled or abrasive filaments, require long component lifespan, and reliable printing without frequent nozzle replacement. Thanks to its easy maintenance and universal use, it is suitable for hobby makers, advanced users, and small businesses that value quality, durability, and efficient printer operation.

Recommendation: For extremely abrasive filaments (e.g. with a high content of carbon fibres), consider using a larger nozzle diameter (e.g. 0.6 mm) to minimise the risk of clogging and extend the hotend’s lifespan.
