Prusa XL build volume: 360 × 360 × 360 mm — what fits, and how to print what doesn't
Quick answer: the Prusa XL prints objects up to 360 × 360 × 360 mm (X × Y × Z, that is width × depth × height) — 46.7 litres, which ranks #20 of 152 printers in the dataset. The largest cube is 360 mm; a thin flat part can reach about 499 mm along the bed diagonal. Anything bigger is split into pieces with connectors — the splitter has a Prusa XL 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 360 × 360 mm bed (diagonal 509 mm, so about 499 mm usable once a margin is left for the brim), and a tall part can stand up to 360 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 Prusa XL needs, allowing a 2 mm margin per piece:
| Model's longest side | On the Prusa XL | 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 (360 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.
Prusa XL notes
The XL is a 360 mm cube — 46.7 litres — and with up to five toolheads it is the Prusa to use for multi-material split pieces. Its segmented heatbed heats only the tiles under the part, so a big split piece placed in one corner costs less power than the same piece centred on a conventional bed. Most things that need splitting for a 250 mm Prusa print whole here; what still needs the splitter is cosplay armour, life-size props and furniture-scale parts.

Split a model for the Prusa XL
- Open splicestl with the Prusa XL preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
- The split runs by itself to 360 × 360 × 360 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 Prusa XL?
360 × 360 × 360 mm (width × depth × height), which is 46.7 litres. That is the manufacturer's stated printable volume as used by splicestl's Prusa XL preset; the physical bed may be a few millimetres larger.
What is the largest object you can print on the Prusa XL?
A 360 mm cube fits outright. A flat part can be longer by lying on the bed diagonal: up to about 499 mm long if it is narrow and under 360 mm tall. A tall part can stand 360 mm high if its footprint is within 360 × 360 mm. Anything that exceeds these in any orientation has to be split.
How do I print something bigger than the Prusa XL'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 Prusa XL preset: load the STL, 3MF or OBJ, choose the preset, and the model is cut on all three axes to fit 360 × 360 × 360 mm with pegs, dovetails or magnet pockets placed at every cut. Download gives one file per piece plus an assembly sheet.
