The Mini+ has been on the market since 2021 and has proven its durability with thousands of community print-hours logged.
Prusa stocks replacement parts for all Mini+ components. Community guides cover every repair scenario.
The lowest-cost way to enter the Prusa ecosystem with a fully supported printer.
The Max4 offers the largest build volume in Qidi's lineup — enabling large functional parts, architectural models, and production batch runs that exceed Plus4 capacity.
The Max4's closed-loop XY adds positional feedback for improved accuracy at high speeds — a differentiating feature at this price tier that reduces dimensional errors on large prints.
Qidi's proven active chamber heating technology scaled to a 390×390 mm bed — critical for consistent ABS, ASA, PA-CF, and PPS-CF results across the full build plate.
