| Property | QIDI Max4COREXY | UltiMaker S7INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | QIDI | UltiMaker |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[1][2] | UltiMaker S7[3] |
| Release date (announcement and actual shipping) | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[1][4] | Not documented |
| Street price (USD; dated snapshot per entry) | $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[1] | $5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1][4] | Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[3][5][6] |
| Market position: superseded? successor announced? | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[1][4] | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[6][7] |

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.
