| Property | QIDI i-FastIDEX | Voron 2.4COREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | Voron Design |
| Class | IDEX | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Tech i-Fast, also written iFast and "I-Fast"[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 the listings checked (Aug 2026)[1][2] | Not documented |
| Street price (USD; dated snapshot per entry) | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[2][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][5][6] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[2][1] | 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][6][7] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][8] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 300 x 300 x 300 mm or 350 x 350 x 350 mm. Sortable value is the 350 mm kit[3][4][6] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | Not documented |
| Net weight (kg) | 33 kg net[2] | Not documented |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Blind-joint aluminium-extrusion frame with a complete panel set; stainless-steel linear rails throughout[4][6] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Enclosed by the supplied panel set. A Nevermore Micro V5 internal circulation filter is included in the LDO kit[6] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | CoreXY on linear rails, with a belted flying gantry on four Z motors[4][3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | LDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers, ready for 48 V upgrades[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[2] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | Clockwork 2 with a Bondtech BMG / Integrated Drive Gear Assembly, in a Stealthburner toolhead[3][4][6] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | E3D Revo Voron (24 V), all-metal, high-flow variant in the Rev D+ kit, with a 60 W heater; upgradeable to a Phaetus Rapido HF for $9.99[3][4][6] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | Not documented |
| Heater cartridge power (W) | Not documented | 60 W (E3D Revo High Flow heater)[3] |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | Not documented |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Not documented | Cast 5083 aluminium plate with a magnetic base and a powder-coated PEI sheet; LDO silicone bed heater with edge-to-edge heating[4][3][6] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Omron inductive probe supplied; Klicky-mod parts included. Voron Tap is available as an add-on rather than standard[3][4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | LDO x Voron Leviathan mainboard (replacing the earlier BTT Octopus), plus a Nitehawk SB USB toolhead PCB[4][3][6] |
| Input voltage (110/220 V, switch or auto) | 110-220 V[2] | Not documented |
| Total rated power draw | 700 W rated[2] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Klipper, hosted on a Raspberry Pi 4B (included in the Fabreeko Rev D+ kit, not in the older 3DJake RevD kit)[3][4][6] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 4.3-inch touchscreen included in the LDO kit[6] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[1][2] | Not documented |
| LED chamber/toolhead lighting | Not documented | COB LED strips included[3][6] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; some parts must be printed by the user, and the LDO kit supplies pre-cut, pre-crimped cables and a heat-set insert soldering tip[6] |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | 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.
