The Bambu Lab H3C prints a model with two nozzle sizes, and each nozzle works with its own layer height. Bambu Lab describes this in a blog post from November 9, 2026 and considers the H3C the first commercially available 3D printer that can do this out of the box.
The software for this is included in Bambu Studio 2.9.1 from November 3, 2026. The release notes call the Mixed-Nozzle mode the most important update of this version, but for now it only applies to the H3C.
How does the slicer divide a model between the nozzles?
Bambu Studio arranges the layers into height ranges. In each range, the fine nozzle prints several thin layers, the large nozzle one thick layer, and at the range boundary both ranges meet at the same height. The slicer itself takes care of layer alignment, tool changes, and path planning.

A watch with a fine dial and a coarse case serves as an example. The 0.2 mm nozzle prints the dial, the 0.4 mm nozzle fills the case. Small nozzles no longer have to take over the layer height of the main part, and large nozzles do not have to switch to thin layers for details.
In Mixed-Nozzle mode, you define the ranges with a paint tool or a modifier box. After changing the model, you re-slice the print, and the division adapts.
Which Bambu Lab printers will get the mode?
So far it only runs on the H3C. Bambu Lab is still developing support for the H2D, H2C, and X2D. The AMS versions of these models differ from the H3C, so the slicer has to take more combinations of filament and nozzles into account. The announcement from November 3, 2026 gives estimates, not fixed dates:
Printer
Without Filament Track Switch
With Filament Track Switch
H2D
November 2026
February 2027
H2C
February 2027
March 2027
X2D
February 2027
March 2027
The date depends on whether a printer has the Filament Track Switch, an optional accessory that Bambu Lab does not explain in more detail in the post. With it, the start for the H2D is pushed back by three months, and for the H2C and the X2D by one month.
For the H2D, H2C, and X2D, the mode is still missing in Bambu Studio 2.9.1. Bambu Lab does not comment in the post on the price and delivery of the H3C in Germany.
What this means for you
If you have an H3C, it is best to install Bambu Studio 2.9.1 right away and test the Mixed-Nozzle mode on a model with a large main body and small, clearly delineated details. Bambu Lab cites exactly that as the strength of the mode.
If you own an H2D, H2C, or X2D, don't plan on the mode yet. First check whether your printer has the Filament Track Switch, because that determines whether the estimate falls in November 2026, February, or March 2027.
If you are planning to buy a Bambu Lab printer because of this mode, the current status is what counts: it is usable on the H3C, and all other dates are estimates.
Bambu Lab published the blog post on the H3C on November 9, 2026.
