Bambu Lab Complete hotend assembly
Highlights of Different Nozzle Diameters
0.2mm Nozzle
Optimal Print Fineness
Extremely small layer gaps
Detailed on the vertical printing surface
0.4mm Nozzle
Optimal Print Quality and Printing Speed
The 0.4mm nozzle is widely regarded as the standard nozzle diameter for modern 3D printers due to its optimal balance between print quality and printing speed. This nozzle size is used in both the Bambu Lab X1 series and the P1 series 3D printers.

[*Note]
- Filaments with carbon fiber, glass fiber, metal, or other inorganic particles tend to clog. 0.2mm nozzle.
- For filaments containing carbon or glass fibers, it is highly recommended to use a hardened steel 0.6mm nozzle to minimize the risk of clogging and abrasion.
- Bambu PLA-CF and Bambu PETG-CF have been extensively tested and have proven to have a low risk of clogging when printed with a hardened steel 0.4mm nozzle while achieving higher print quality simultaneously.
