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.

The specifications that matter

Process: FDM
Nominal build volume: 180 × 180 × 180 mm
Enclosure: Open frame
Multicolor: No compatible MMU: the MINI+'s Bowden extruder does not support Prusa's MMU multicolor system.
Materials: PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, and filled materials per Prusa Research.

Allow room for supports and the chosen orientation. Confirm the exact nozzle, feeder, included accessories and installation clearance against the manual and seller’s listing.

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

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.
