Why consider it?

A compact format that stays within the Prusa ecosystem (PrusaSlicer, Prusa Connect) with an automatic SuperPINDA leveling sensor.

What to verify

A 180 mm build volume and no MMU compatibility rule it out for large parts or automated multicolor printing.

How much space does it need?

The Prusa MINI+ measures 380 × 330 × 380 mm (15 × 13 × 15 in) for a 180 × 180 × 180 mm (7.1 × 7.1 × 7.1 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 12% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

Which projects is it for?

The MINI+ is an open-frame FDM printer with a build volume of 180 × 180 × 180 mm per Prusa Research, built to fit on a small desk or start a small print farm. It suits figurines, small functional parts, and learning FDM printing without a large budget.

The compact format is not a substitute for a larger-volume machine on bulky parts, but it keeps most of the Prusa ecosystem: PrusaSlicer, Prusa Connect for remote monitoring, and a SuperPINDA sensor for automatic first-layer leveling.

Materials and setup

Prusa Research lists broad material support: PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, flexible filaments, and filled materials (wood, composites), with a hotend up to 280°C and a heatbed up to 100°C.

The MINI+ uses a Bowden extruder that is not compatible with Prusa's MMU system: there is no official automated multicolor option for this model, unlike the MK4S or the CORE One.

What the bundle includes or not

Per Prusa Research's listing, the semi-assembled version includes a smooth PEI sheet, a filament sensor, a power cable, an English handbook, and free access to an online 3D-printing course.

The 2.8-inch color screen is standard. The MINI enclosure remains a separate accessory worth adding for regular ABS or ASA use; check precisely what a listing includes before buying.

Alternatives to compare

For a larger volume from the same maker, the MK4S is the direct comparison, with the added benefit of MMU3 compatibility for multicolor. The Prusa Research page places the MINI+ within the rest of the lineup.

The beginner's buying guide helps decide between this compact format and a more versatile machine depending on the size of parts you plan to print.

Frequently asked questions

What is the build volume of the Prusa MINI+?

Prusa Research lists a 180 × 180 × 180 mm (7.1 × 7.1 × 7.1 in) build volume (width × depth × height). That is the largest theoretical part size; supports, brim and orientation reduce the usable space.

How big is the Prusa MINI+?

According to Prusa Research, the Prusa MINI+ measures 380 × 330 × 380 mm (15 × 13 × 15 in) (width × depth × height) and weighs 4.5 kg (9.9 lb). Leave extra clearance for the spool, cables and airflow, and more if you add a multicolor unit.

Is the Prusa MINI+ enclosed?

No, it is an open-frame printer. It suits PLA and PETG; ABS and ASA are better handled by an enclosed machine. Its nozzle reaches 280 °C (536 °F) and its bed 100 °C (212 °F).

Can the MINI+ print in multiple colors?

Not automatically: its Bowden extruder isn't compatible with Prusa's MMU. Manual color changes remain possible, but there's no official automated multicolor system.

What real build volume should you expect?

180 × 180 × 180 mm per Prusa Research, a format suited to small parts and figurines rather than bulky objects or large batches.

Do you need an enclosure to print ABS on the MINI+?

It's not included by default: the MINI enclosure is a separate accessory recommended to stabilize temperature for regular ABS or ASA use.
