What is build volume?

Build volume is the maximum X, Y and Z dimensions your printer can print. It is determined by the physical travel limits of the print head and bed. The actual usable volume may be slightly less than the stated specifications.

My part is slightly too big — what can I do?

You can rotate the part diagonally on the bed to use the diagonal distance, split the part into sections and glue them together, or scale it down slightly.

Does build volume include the full bed?

Stated build volume is usually the mechanical maximum. In practice, you lose a few mm at the edges due to clips, probe offsets, or bed levelling margins. Budget 5-10mm less on each axis.

Build Volume Calculator — Fit Check

Calculate usable build volume and check if your model fits the print area.

Build X

Printer's maximum bed travel on the X axis (mm). Ender 3 = 235 physical / 220 usable.

Build Y

Printer's maximum bed travel on the Y axis (mm). Ender 3 = 235 physical / 220 usable.

Build Z

Maximum print height — how far the nozzle can travel up the Z axis (mm).

Part X

Model's bounding-box width on the X axis (mm) — read it from your slicer's object dimensions.

Part Y

Model's bounding-box depth on the Y axis (mm) — read it from your slicer's object dimensions.

Part Z

Model's bounding-box height on the Z axis (mm) — read it from your slicer's object dimensions.

How We Calculate This

Formula

Usable build dimensions = X − 2 × edge margin, Y − 2 × edge margin, Z − Z clearance
Build volume (litres) = usable X × usable Y × usable Z (mm) ÷ 1,000,000 (1 litre = 1,000,000 mm³ = 1,000 cm³)
Fits check = part dimension ≤ usable build dimension (each axis)
Max scale = min(usable build / part) for each axis × 100%
Volume utilisation = part bounding box ÷ usable build volume × 100

Raw X × Y × Z in millimetres gives cubic millimetres, so the calculator divides by 1,000,000 to report litres. Edge margin and Z clearance are subtracted first, so every figure here — the build volume, the fit check, the max scale and the utilisation percentage — is measured against the usable (post-margin) build envelope, not the raw mechanical maximum.

The calculator checks each axis independently. The maximum scale factor is limited by whichever axis would hit the build limit first.
