| Property | Original Prusa MINI+BEDSLINGER | QIDI Max4COREXY |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | QIDI |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Original Prusa MINI+ Semi-assembled 3D Printer[1] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][4] |
| Street price (USD; dated snapshot per entry) | $508.33 on prusa3d.com, Aug 2026[5] | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[1][6] | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[2][4] |
| Market position: superseded? successor announced? | Not documented | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[2][4] |

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
