Upgrade your BambuLab A1 or A1 Mini with this 0.4mm Hardened Steel Nozzle Hotend Kit, built for users who print more than just standard PLA. Designed as a 3rd-party compatible replacement hotend, this kit is ideal for handling abrasive filaments like carbon fiber blends, glow-in-the-dark, wood-fill, and other particle-filled materials that can wear out regular brass nozzles fast.
The hardened steel nozzle offers improved durability and long service life, helping you maintain consistent extrusion quality over extended print hours. Whether you’re running a print farm, prototyping functional parts, or producing high-detail prints, this A1/A1 Mini hotend kit is a reliable upgrade for smoother prints and fewer nozzle changes.
Perfect for makers who want a tough, long-lasting nozzle while keeping the standard 0.4mm size for a great balance of speed and detail.
