Upgrade your Bambu Lab X1 and P1P series 3D printers with the Bambu Lab Brass Big Flow Nozzle, engineered to deliver superior extrusion performance, exceptional heat transfer, and highly stable filament flow. Available in multiple nozzle diameters—0.4mm, 0.5mm, 0.6mm, 0.8mm, and 1.0mm—this nozzle series provides the perfect balance of precision and speed for all printing needs.

Crafted from high-quality brass, each nozzle offers excellent thermal conductivity, ensuring rapid, consistent heating and smooth extrusion even during long or high-speed prints. The optimized internal channel reduces friction and minimizes clogging, resulting in cleaner layers, better surface finish, and improved print accuracy.

With an M6 thread and precise machining quality, the Bambu Lab Brass Big Flow Nozzle fits perfectly into the X1/P1P hotend, providing reliable sealing, accurate alignment, and consistent extrusion. Whether you’re printing detailed models with a fine nozzle or high-speed prototypes with a larger diameter, this nozzle series delivers outstanding and reliable performance.

Compatible with a wide range of materials—including PLA, ABS, PETG, TPU, and other 1.75mm filaments—this nozzle is a versatile upgrade suitable for hobbyists, precision makers, and professional users.
