Bambu Lab H3C can print mixed nozzles at different layer heights

It is a quiet day for new products, with one item worth a report: Bambu Lab has explained how its H3C printer mixes nozzle sizes and layer heights in a single print.

Bambu Lab explains mixed layer heights on the H3C

In our earlier report on the H3C announcement we covered the printer itself. Now Bambu Lab has described one feature in detail. Most slicers can change layer height as a print rises, but regions side by side follow the same layer schedule. Bambu Lab says the H3C is, to its knowledge, the first commercially available 3D printer that lets different nozzle sizes print different layer heights on the same surface.

The company’s example is a watch: a 0.2 mm nozzle draws the fine dial in thin layers, while a 0.4 mm nozzle prints the case in thick layers. The slicer groups the print into layer bands. When the thick layer is three times as tall as the thin one, the fine nozzle lays three layers while the large nozzle lays one, and both regions meet at the same height. In Bambu Studio’s mixed-nozzle mode you paint a region or use a modifier box, and the software plans the tool changes and travel paths. Bambu Lab says it also spares you from splitting a model by hand.

Bambu Lab also says native mixed-nozzle support for the H2D, H2C and X2D is in development. It gives no date in this post, and it names no new European price or availability.
