ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)QIDI Max4, sold as "Max4 High-Temp 3D Printer"[1][2]Voron 2.4, current revision R2, kits shipping as Rev D and Rev D+. Sold as "Voron 2.4 R2 (Rev D+) 3D Printer Kit by LDO"[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 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]$1,399.99 for the LDO Rev D+ kit at Fabreeko (300 mm and 350 mm are the same price), on pre-order with a mid-September estimate, checked Aug 2026. Fabreeko's live feed shows the base 2.4 kit listing at $1,299.99 and available. 3DJake lists an LDO 350 RevD kit but will not ship to the US[3][6][7]
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]Sizes 250, 300 and 350 mm; LDO ships Rev D and Rev D+. Colours black, space grey, blue. Do not confuse with the Trident: the 2.4 lifts the whole gantry on four belted Z motors, the Trident lifts the bed on three screws. The Rev D+ kit includes a Raspberry Pi 4B; the older 3DJake-listed RevD kit explicitly does not include a Pi[3][4][7][8]

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.
