Split a model that is too big for the Bambu Lab H2D

The Bambu Lab H2D prints up to 325 × 320 × 325 mm. SplitSTL splits your model into parts that fit, with pins or magnets, engraved part numbers and 3MF plates ready to slice.

Build volume of the Bambu Lab H2D

Build plate 325 × 320 mm, height 325 mm. Keeping a 5 mm margin, each part must fit in 320 × 315 × 320 mm. Parts can be turned on the plate, so SplitSTL also picks the orientation: a long, flat object can reach about 439 mm along the diagonal.

Frequently asked questions

What is the maximum print size of the Bambu Lab H2D?

The build volume of the Bambu Lab H2D is 325 × 320 × 325 mm. Anything bigger has to be scaled down or split into several parts.

How many parts for a cosplay helmet on the H2D?

A helmet of about 24 × 28 × 30 cm needs at least 1 part on the H2D with a grid split. The natural-joint split of SplitSTL Pro can follow the helmet’s design lines instead.

How do I join the printed parts?

SplitSTL drills aligned pin holes (printable pins included) or magnet pockets, and engraves each part’s number on its cut face. An illustrated assembly guide comes with the export.
