Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[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 on the pages checked (Aug 2026)[1][2]Not documented
Street price (USD; dated snapshot per entry)$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[2]$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)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[1][7][8]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][9]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable175 x 180 x 170 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)370 x 362 x 397 mm[1]Not documented
Net weight (kg)10.5 kg[1]Not documented
Frame construction & materialQIDI publishes no frame-material breakdown for this model[1]Blind-joint aluminium-extrusion frame with a complete panel set; stainless-steel linear rails throughout[4][6]
Enclosure: open / enclosed; panel material; door/lidNo heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[1]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)CoreXY[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 documentedLDO 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)<=500 mm/s (manufacturer claim)[1][2]Not documented
Max acceleration (claimed, mm/s²)20,000 mm/s2 (manufacturer claim)[2]Not documented
Max volumetric flow claimed (mm³/s)30 mm3/s extruder flow (manufacturer claim)[1][2]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect-drive extruder, single, 1.75 mm filament[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?)Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[1][2]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)<=300 °C claimed[1][2]Not documented
Heater cartridge power (W)Not documented60 W (E3D Revo High Flow heater)[3]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Brass[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit<=120 °C claimed[1][2]Not documented
Bed surface (material, texture, coating), single/double-sidedDouble-sided flexible magnetic RF plate[1]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)16-point automatic bed levelling per QIDI's US page; probe technology not named[2]Omron inductive probe supplied; Klicky-mod parts included. Voron Tap is available as an add-on rather than standard[3][4]
Mesh grid size (probe point count — firmware evidence)16 points (QIDI's US page). Not verified against firmware[2]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted; type and location not published[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedLDO x Voron Leviathan mainboard (replacing the earlier BTT Octopus), plus a Nitehawk SB USB toolhead PCB[4][3][6]
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxCortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[1]Not documented
Input voltage (110/220 V, switch or auto)100-240 VAC, 50/60 Hz[1]Not documented
Total rated power draw350 W rated[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper[2]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?4.3-inch touchscreen[2]4.3-inch touchscreen included in the LDO kit[6]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi and USB. No Ethernet listed for this model[1][2]Not documented
LED chamber/toolhead lightingNot documentedCOB LED strips included[3][6]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-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]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)1-year coverage (QIDI standard store terms)[10]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.
