What is the Prusa MK3S+ build volume?

The nominal build volume is 250 × 210 × 210 mm. It is 10 mm shorter in Z than the MK4.

Can the MK3S+ print a 220 mm tall model?

No, not in one piece on the 210 mm Z axis. Check whether a split at a natural seam preserves the part's strength.

Why does my model fit after rotation?

The checker tries all six axis-aligned permutations. A long Y dimension can become an X span on the 250 mm axis, but the new orientation may need supports.

Can the Prusa MK3S+ print ABS?

It can, but the open frame needs an enclosure and controlled cooling. For large ABS parts, expect more warp risk than on an enclosed printer.

Is the MK3S+ good for PETG?

Yes. PETG prints reliably on the MK3S+ with a clean sheet and dry filament. Remember the 210 mm Y depth and 210 mm Z height when scaling an existing profile.

Prusa MK3S+ build volume and fit check

The MK3S+ has a nominal 250 × 210 × 210 mm build volume. It shares the MK4's footprint but not its height: the MK3S+ stops at 210 mm in Z. Long parts can use the 250 mm X axis, while the 210 mm Y depth is usually the first limit to check.

Model-specific limits

The Z height is 210 mm, not the MK4's 220 mm. A 215 mm part will fit an MK4 profile and fail on an MK3S+.
The plate is 250 × 210 mm. A part that fits along X may still need a quarter turn to fit the Y depth.
The open frame loses heat quickly, so ABS and ASA need an enclosure and controlled cooling. Geometry alone is not enough.

What fits

Everyday functional parts

The MK3S+ remains a reliable PLA and PETG machine for brackets, spacers and replacement parts within 250 × 210 mm.

Parts from an existing MK3S+ profile

Use this page to confirm a new model still fits a proven profile before copying slicer settings from an older project.

Tall single-piece parts

Check the 210 mm Z limit early. If the model is just over, rotating it is usually not enough; split it at a natural seam instead.

Orientation tips

Include the brim width in the XY clearance when the footprint is close to 250 × 210 mm.
A 90-degree rotation can turn a 230 mm Y overhang into a 230 mm X span that fits.
For a tall part, confirm both the model height and the slicer's Z limit; the nominal bed height is an upper bound.
