Bambu P1 Hardened Steel Hot End

Print Abrasives Without Compromise

The Bambu P1 Hardened Steel Hot End is an OEM Bambu Lab replacement hotend engineered for printing abrasive and high-temperature filaments. Swap out your stock brass hotend and unlock reliable printing with carbon fiber, glass fiber, glow-in-the-dark, and other particle-filled materials that would quickly wear down a standard nozzle.

Why Hardened Steel?

• Dramatically higher wear resistance vs. brass — essential for abrasive filaments
• Handles high-temp materials like PA-CF, PET-CF, and PLA-CF with ease
• Maintains dimensional accuracy over extended print runs
• OEM Bambu Lab part — guaranteed fit for P1P and P1S printers

Compatible Filaments

• Carbon fiber filled (PA-CF, PET-CF, PLA-CF, ABS-CF)
• Glass fiber filled
• Glow-in-the-dark
• Metal-filled and other abrasive composites

Key Details

If you're serious about printing advanced materials on your P1-series printer, the hardened steel hotend is an essential upgrade.
