Documented for other Prusa Research models, not the Prusa Research MINI / MINI+

These parts are easy to mistake for a fit. Their makers name a related model but not the Prusa Research MINI / MINI+, so we don’t list them above.

Filament notes for the Prusa Research MINI / MINI+

Start with Best Filament for the Prusa MINI and MINI+ (2026), which covers what the printercan and can’t print according to the maker.

The Prusa Research MINI / MINI+ uses 1.75 mm filament. Every spool in our filament shortlists is 1.75 mm, but check the exact listing before you buy. The stock extruder is Bowden, so firmer flexible grades are the safer starting point; check the TPU guide before buying soft TPU.

For a material direction matched to your printer, use the filament finder with the MINI / MINI+ preselected.
