Product Description

Alternative hardened Hotend 0,4 mm is a fully compatible replacement for the original Bambu Hotend for H2D/H2S/P2S. Thanks to the optimized melt zone and hardened steel nozzle, it is ready for high-speed printing with high volumetric flow while resisting highly abrasive filaments such as PLA/PETG-CF, PA-CF, glass fibers or glow-in-the-dark. (us.store.bambulab.com) The hotend is designed as a plug-and-play upgrade – the design corresponds to the original Bambu Lab hotend for the H2/P2S series, so you can simply replace it for your existing hotend without printer modifications.

Main Advantages

• High volumetric flow (~40 mm³/s for PLA, up to ~48 mm³/s for PLA Matte, ~32 mm³/s for PETG HF) – allows for substantially shorter printing times compared to a standard hardened hotend. (eu.store.bambulab.com)
• Hardened steel nozzle 0,4 mm – suitable for abrasive materials (CF, GF, metal, glow) and long-term operation without rapid wear. (us.store.bambulab.com)
• Hotend construction – enlarged melt zone improves filament melting and limits underextrusion at high speeds.
• Quick swap design – the special construction of Bambu H2/P2S allows for easy release and replacement of the hotend using a latch, without complex interventions. (us.store.bambulab.com)
• Full compatibility with Bambu Lab H2D/H2S/P2S – dimensionally and electrically corresponds to the original.
• Wide filament compatibility – from common PLA and PETG to technical and composite materials (according to filament manufacturer recommendations and printer limits).

Usage and Tips

• Ideal for:
  • high-speed printing of large objects (sculptures, covers, parts with high infill),
  • functional and technical parts from ABS/ASA/PC,
  • printing abrasive filaments (CF/GF, metal, glow), where standard brass nozzles wear out quickly.
• For maximum benefit:
  • use a higher volumetric limit in the slicer settings (Bambu Studio/OrcaSlicer),
  • check recommended speeds and temperatures for the specific filament,
  • after hotend replacement, perform calibrations (flow, pressure advance, or input shaping according to printer capabilities).

When handling the hotend, always prioritize safety – turn off the printer and wait for the hotend to cool down before disassembly / assembly.

Filament Compatibility

Thanks to the hardened steel and construction, the hotend is suitable for a wide range of materials (always considering the limits of the specific H2/P2S printer):

• Common materials: PLA, PLA Matte, PLA Silk, PLA Gradient, PETG, PETG HF, ABS, ASA.
• Technical materials: PC, PC FR, PA/PET (within H2/P2S limits), special support materials.
• Composites and abrasives: PLA/PETG-CF, ASA/PA-CF (as recommended – some combinations have limitations for smaller diameters in official tables, but hardened steel significantly reduces wear), PLA Metal, PLA Marble, glow-in-the-dark.

To minimize the risk of nozzle clogging with highly filled filaments, it is recommended to:

• follow the recommended speed range and temperatures,
• ensure high-quality drying of hygroscopic materials (PA, PET-CF, etc.),
• regularly perform cleaning prints (e.g., with cleaning filament or PETG).
