Anycubic Kobra Max build volume: 400 × 400 × 450 mm — what fits, and how to print what doesn't

· · from the 152-printer build-volume dataset

Quick answer: the Anycubic Kobra Max prints objects up to 400 × 400 × 450 mm (X × Y × Z, that is width × depth × height) — 72.0 litres, which ranks #13 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 Kobra 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 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 Kobra Max needs, allowing a 2 mm margin per piece:

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 Kobra Max notes

The Kobra Max is the Chiron's successor at the same 400 × 400 × 450 mm. The 450 mm Z is tall enough for most standing props whole; what owners split are pieces whose footprint overflows 400 mm or whose print time is unreasonable in one go.

Split a model for the Anycubic Kobra Max

  1. Open splicestl with the Anycubic Kobra Max preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
  2. 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.
  3. 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 Kobra Max?

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 Kobra Max preset; the physical bed may be a few millimetres larger.

What is the largest object you can print on the Anycubic Kobra Max?

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 Kobra 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 Anycubic Kobra Max 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.
