Identity
BrandFlashForgeQIDI
ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Flashforge AD5X, sold as "AD5X - Multicolor 3D Printer for High-Speed, Full-Color Printing"[1][2]QIDI Max4, sold as "Max4 High-Temp 3D Printer"[3][4]
Release date (announcement and actual shipping)Not documentedNot published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[3][5]
Street price (USD; dated snapshot per entry)$399.00 sale against a $549.00 compare-at price on flashforge.com, in stock, with a further $50 off at checkout, checked Aug 2026. A refurbished AD5X is listed at $315.00[1][2]$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[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Shares the 220 mm Adventurer chassis with the 5M and 5M Pro but differs on the points that matter: 300 °C nozzle (vs 280 °C), 4-colour IFS unit, NO air filtration, NO auto shutdown, and a 300 mm/s print speed against a 600 mm/s travel speed. 3DJake and eolasprints both describe it as open-frame[1][6][7][8]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[3][5]
Market position: superseded? successor announced?Not documentedCurrent large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[3][5]

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.
