| Property | QIDI Max4COREXY | QIDI X-Smart 3COREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[1][2] | QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[3][4] |
| 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][5] | Not published by QIDI on the pages checked (Aug 2026)[3][4] |
| 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] | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[4] |
| 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][5] | Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[3][6][7] |
| Market position: superseded? successor announced? | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[1][5] | Not documented |

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.
