Bambu Lab H2D build volume: 350 × 320 × 325 mm — what fits, and how to print what doesn't
Quick answer: the Bambu Lab H2D prints objects up to 350 × 320 × 325 mm (X × Y × Z, that is width × depth × height) — 36.4 litres, which ranks #30 of 152 printers in the dataset. The largest cube is 320 mm; a thin flat part can reach about 464 mm along the bed diagonal. Anything bigger is split into pieces with connectors — the splitter has a Bambu Lab H2D preset.
What the numbers mean for your model
Build volume is quoted as the box the nozzle can reach, X × Y × Z. A model fits whole when it fits that box in some orientation, which is more forgiving than it sounds: a long flat part can lie diagonally across the 350 × 320 mm bed (diagonal 474 mm, so about 464 mm usable once a margin is left for the brim), and a tall part can stand up to 325 mm if its footprint fits. The splitter checks every orientation before it decides a model needs cutting, and reports "already fits" when it does.
When it does not fit, the number of pieces depends on which axis overflows. If only the longest dimension is too big, this is what a Bambu Lab H2D needs, allowing a 2 mm margin per piece:
| Model's longest side | On the Bambu Lab H2D | Piece length |
|---|---|---|
| 250 mm | fits whole | — |
| 300 mm | fits whole | — |
| 400 mm | 2 pieces | 200 mm each |
| 500 mm | 2 pieces | 250 mm each |
| 600 mm | 2 pieces | 300 mm each |
| 800 mm | 3 pieces | 267 mm each |
Pieces along the printer's longest axis (350 mm). A model that overflows two axes needs the product of the two counts — the splitter plans that automatically, and usually finds a layout with fewer pieces than the naive grid by rotating the model first.
Bambu Lab H2D notes
The H2D is Bambu's largest printer: 350 × 320 × 325 mm with the dual-nozzle head. Bambu's own figures narrow the width when both nozzles are in use, so a part that needs the full 350 mm should be planned as a single-nozzle print; if a two-material split piece is wider than the dual-nozzle limit, splitting it in X with a flat cut and a few pegs is simpler than fighting the toolhead. At 36 litres it prints most things whole that a 256 mm Bambu needs split, which is why it sits near the top of the 152-printer table.

Split a model for the Bambu Lab H2D
- Open splicestl with the Bambu Lab H2D preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
- The split runs by itself to 350 × 320 × 325 mm minus a margin, on all three axes at once. Drag a cut handle to move a seam; Shift-click the model to mark a spot a seam must avoid.
- Pick connectors — pegs by default; dovetails, finger joints, magnet pockets, dowel holes, screw joints or your own — and download the zip: one file per piece lying flat, the connectors, a README and an assembly sheet.
Frequently asked questions
What is the build volume of the Bambu Lab H2D?
350 × 320 × 325 mm (width × depth × height), which is 36.4 litres. That is the manufacturer's stated printable volume as used by splicestl's Bambu Lab H2D preset; the physical bed may be a few millimetres larger.
What is the largest object you can print on the Bambu Lab H2D?
A 320 mm cube fits outright. A flat part can be longer by lying on the bed diagonal: up to about 464 mm long if it is narrow and under 325 mm tall. A tall part can stand 325 mm high if its footprint is within 350 × 320 mm. Anything that exceeds these in any orientation has to be split.
How do I print something bigger than the Bambu Lab H2D's build volume?
Split it into pieces that each fit, add connectors at the cuts, print the pieces and join them. The free browser splitter at splicestl.com has a Bambu Lab H2D preset: load the STL, 3MF or OBJ, choose the preset, and the model is cut on all three axes to fit 350 × 320 × 325 mm with pegs, dovetails or magnet pockets placed at every cut. Download gives one file per piece plus an assembly sheet.
