Raise3D Pro3 build volume: 300 × 300 × 300 mm — what fits, and how to print what doesn't
Quick answer: the Raise3D Pro3 prints objects up to 300 × 300 × 300 mm (X × Y × Z, that is width × depth × height) — 27.0 litres, which ranks #51 of 152 printers in the dataset. The largest cube is 300 mm; a thin flat part can reach about 414 mm along the bed diagonal. Anything bigger is split into pieces with connectors — the splitter has a Raise3D Pro3 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 300 × 300 mm bed (diagonal 424 mm, so about 414 mm usable once a margin is left for the brim), and a tall part can stand up to 300 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 Raise3D Pro3 needs, allowing a 2 mm margin per piece:
| Model's longest side | On the Raise3D Pro3 | Piece length |
|---|---|---|
| 250 mm | fits whole | — |
| 300 mm | 2 pieces | 150 mm each |
| 400 mm | 2 pieces | 200 mm each |
| 500 mm | 2 pieces | 250 mm each |
| 600 mm | 3 pieces | 200 mm each |
| 800 mm | 3 pieces | 267 mm each |
Pieces along the printer's longest axis (300 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.
Raise3D Pro3 notes
The Pro3 prints 300 × 300 × 300 mm, 27 litres, with dual extruders (the Pro3 Plus adds height to 605 mm). It is a professional enclosed machine where splitting usually serves logistics — printing pieces on several machines in parallel — more than fit, which is what splicestl's print farm mode plans.

Split a model for the Raise3D Pro3
- Open splicestl with the Raise3D Pro3 preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
- The split runs by itself to 300 × 300 × 300 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 Raise3D Pro3?
300 × 300 × 300 mm (width × depth × height), which is 27.0 litres. That is the manufacturer's stated printable volume as used by splicestl's Raise3D Pro3 preset; the physical bed may be a few millimetres larger.
What is the largest object you can print on the Raise3D Pro3?
A 300 mm cube fits outright. A flat part can be longer by lying on the bed diagonal: up to about 414 mm long if it is narrow and under 300 mm tall. A tall part can stand 300 mm high if its footprint is within 300 × 300 mm. Anything that exceeds these in any orientation has to be split.
How do I print something bigger than the Raise3D Pro3'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 Raise3D Pro3 preset: load the STL, 3MF or OBJ, choose the preset, and the model is cut on all three axes to fit 300 × 300 × 300 mm with pegs, dovetails or magnet pockets placed at every cut. Download gives one file per piece plus an assembly sheet.
