Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)QIDI X-Max 3, listed by QIDI as "Qidi Tech X-Max 3 3D Printer" and in navigation as X-Max3[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 by QIDI; the product page carries a discontinuation notice rather than a launch date (checked Aug 2026)[1]Not documented
Street price (USD; dated snapshot per entry)$899.00 (from a $999.00 sale reference) on us.qidi3d.com but marked Sold Out and discontinued, checked Aug 2026. 3D Printers Online Store lists $1,099 USD, also out of stock[1][5]$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)Same-generation siblings X-Plus 3 (280x280x270, 500 mm/s, 800 W) and X-Smart 3 (175x180x170, no chamber heating, 300 °C, 350 W). All three share the Cortex-A53 1.5 GHz / 1 GB DDR3 / 8 GB eMMC control board, so shared-board specs are not evidence of shared print specs. Replaced by the Max4[2][8][9][10]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][11]
Market position: superseded? successor announced?Discontinued and out of production; QIDI directs buyers to the Max4[1]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.
