QIDI Q1 Pro build volume: 245 × 245 × 240 mm — what fits, and how to print what doesn't
Quick answer: the QIDI Q1 Pro prints objects up to 245 × 245 × 240 mm (X × Y × Z, that is width × depth × height) — 14.4 litres, which ranks #92 of 152 printers in the dataset. The largest cube is 240 mm; a thin flat part can reach about 336 mm along the bed diagonal. Anything bigger is split into pieces with connectors — the splitter has a QIDI Q1 Pro 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 245 × 245 mm bed (diagonal 346 mm, so about 336 mm usable once a margin is left for the brim), and a tall part can stand up to 240 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 QIDI Q1 Pro needs, allowing a 2 mm margin per piece:
| Model's longest side | On the QIDI Q1 Pro | Piece length |
|---|---|---|
| 250 mm | 2 pieces | 125 mm each |
| 300 mm | 2 pieces | 150 mm each |
| 400 mm | 2 pieces | 200 mm each |
| 500 mm | 3 pieces | 167 mm each |
| 600 mm | 3 pieces | 200 mm each |
| 800 mm | 4 pieces | 200 mm each |
Pieces along the printer's longest axis (245 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.
QIDI Q1 Pro notes
The Q1 Pro is an enclosed CoreXY with a heated chamber at 245 × 245 × 240 mm — a little wider than an Ender 3 and a little shorter. The heated chamber is the reason to pick it for split models in ABS, ASA and nylon: the pieces come out dimensionally stable, so a peg clearance of 0.15 mm works where a cold-chamber printer needs 0.25.

Split a model for the QIDI Q1 Pro
- Open splicestl with the QIDI Q1 Pro preset selected and drop the STL, 3MF or OBJ on the page. Nothing is uploaded.
- The split runs by itself to 245 × 245 × 240 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 QIDI Q1 Pro?
245 × 245 × 240 mm (width × depth × height), which is 14.4 litres. That is the manufacturer's stated printable volume as used by splicestl's QIDI Q1 Pro preset; the physical bed may be a few millimetres larger.
What is the largest object you can print on the QIDI Q1 Pro?
A 240 mm cube fits outright. A flat part can be longer by lying on the bed diagonal: up to about 336 mm long if it is narrow and under 240 mm tall. A tall part can stand 240 mm high if its footprint is within 245 × 245 mm. Anything that exceeds these in any orientation has to be split.
How do I print something bigger than the QIDI Q1 Pro'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 QIDI Q1 Pro preset: load the STL, 3MF or OBJ, choose the preset, and the model is cut on all three axes to fit 245 × 245 × 240 mm with pegs, dovetails or magnet pockets placed at every cut. Download gives one file per piece plus an assembly sheet.
