Know before you buy
This hotend assembly is specifically designed for the Bambu Lab A1 and A1 Mini 3D printers.
The 0.8 mm nozzle allows for a significantly higher flow rate, which drastically reduces print times for large objects. It is ideal for structural parts or prototypes where speed is prioritized over fine detail.
Yes, the hardened steel construction is specifically engineered to resist the wear caused by abrasive materials like carbon fiber or glass-filled filaments, which would quickly degrade a standard brass nozzle.
Yes, you must update your slicer settings to reflect the 0.8 mm nozzle diameter. This ensures the software correctly calculates extrusion widths and print speeds for the larger nozzle.
This is a complete hotend assembly, which includes the nozzle, heater, and thermistor. It is designed as a direct, drop-in replacement for your existing A-series hotend.
