Creality Ender 3 Max build volume: 300 × 300 × 340 mm — what fits, and how to print what doesn't
Quick answer: the Creality Ender 3 Max prints objects up to 300 × 300 × 340 mm (X × Y × Z, that is width × depth × height) — 30.6 litres, which ranks #44 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 Creality Ender 3 Max 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 340 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 Creality Ender 3 Max needs, allowing a 2 mm margin per piece:
| Model's longest side | On the Creality Ender 3 Max | 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 (340 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.
Creality Ender 3 Max notes
The Ender 3 Max steps the family up to 300 × 300 × 340 mm — 30.6 litres, two and a half times the standard Ender 3 — so most helmets and busts that need splitting on a 220 mm bed print whole. The 340 mm Z is unusually tall for the price, which makes it a good target for pieces that stand on a flat cut face.

Split a model for the Creality Ender 3 Max
- Open splicestl with the Creality Ender 3 Max preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
- The split runs by itself to 300 × 300 × 340 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 Creality Ender 3 Max?
300 × 300 × 340 mm (width × depth × height), which is 30.6 litres. That is the manufacturer's stated printable volume as used by splicestl's Creality Ender 3 Max preset; the physical bed may be a few millimetres larger.
What is the largest object you can print on the Creality Ender 3 Max?
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 340 mm tall. A tall part can stand 340 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 Creality Ender 3 Max'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 Creality Ender 3 Max preset: load the STL, 3MF or OBJ, choose the preset, and the model is cut on all three axes to fit 300 × 300 × 340 mm with pegs, dovetails or magnet pockets placed at every cut. Download gives one file per piece plus an assembly sheet.
