Anycubic Chiron build volume: 400 × 400 × 450 mm — what fits, and how to print what doesn't
Quick answer: the Anycubic Chiron prints objects up to 400 × 400 × 450 mm (X × Y × Z, that is width × depth × height) — 72.0 litres, which ranks #12 of 152 printers in the dataset. The largest cube is 400 mm; a thin flat part can reach about 556 mm along the bed diagonal. Anything bigger is split into pieces with connectors — the splitter has a Anycubic Chiron 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 400 × 400 mm bed (diagonal 566 mm, so about 556 mm usable once a margin is left for the brim), and a tall part can stand up to 450 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 Anycubic Chiron needs, allowing a 2 mm margin per piece:
| Model's longest side | On the Anycubic Chiron | Piece length |
|---|---|---|
| 250 mm | fits whole | — |
| 300 mm | fits whole | — |
| 400 mm | fits whole | — |
| 500 mm | 2 pieces | 250 mm each |
| 600 mm | 2 pieces | 300 mm each |
| 800 mm | 2 pieces | 400 mm each |
Pieces along the printer's longest axis (450 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.
Anycubic Chiron notes
The Chiron is a 400 × 400 × 450 mm bed-slinger, 72 litres, and "anycubic chiron build volume" is still a frequent search years after launch because so many are in use. The bed is fully printable. Big flat pieces on a bed this size are prone to corner lift in PETG; splitting a wide part in two with a dovetail removes the problem without glue.

Split a model for the Anycubic Chiron
- Open splicestl with the Anycubic Chiron preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
- The split runs by itself to 400 × 400 × 450 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 Anycubic Chiron?
400 × 400 × 450 mm (width × depth × height), which is 72.0 litres. That is the manufacturer's stated printable volume as used by splicestl's Anycubic Chiron preset; the physical bed may be a few millimetres larger.
What is the largest object you can print on the Anycubic Chiron?
A 400 mm cube fits outright. A flat part can be longer by lying on the bed diagonal: up to about 556 mm long if it is narrow and under 450 mm tall. A tall part can stand 450 mm high if its footprint is within 400 × 400 mm. Anything that exceeds these in any orientation has to be split.
How do I print something bigger than the Anycubic Chiron'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 Anycubic Chiron preset: load the STL, 3MF or OBJ, choose the preset, and the model is cut on all three axes to fit 400 × 400 × 450 mm with pegs, dovetails or magnet pockets placed at every cut. Download gives one file per piece plus an assembly sheet.
