2 selected · all documented properties
| Property | QIDI i-FastIDEX | Sovol ZeroCOREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | Sovol |
| 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] | Sovol Zero 3D Printer[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] | $389.00 on sovol3d.com against a $499.00 compare-at price, but marked Sold out, checked Aug 2026. Sovol's own announcement article quotes from $359.00[3][4][5] |
| 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] | No sibling variants at the time of checking. Sovol positions it against the Voron 0 and Bambu Lab P1P. Note the bed and nozzle limits are higher than the larger SV08 (120 vs 100 °C bed, 350 vs 300 °C nozzle), so SV08 figures must not be carried across[3][5][6] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][7] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 152.4 x 152.4 x 152.5 mm advertised[3][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | 345 x 420 x 475 mm[3] |
| Net weight (kg) | 33 kg net[2] | Not documented |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Full linear rails on all axes; CoreXY with two motors sharing the moving mass[5] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Fully enclosed[5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | CoreXY[5] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails on all axes[5] |
| 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] | 1200 mm/s maximum (manufacturer claim). Sovol's own material acknowledges 700 mm/s as the realistic figure for detailed prints[3][5] |
| Max acceleration (claimed, mm/s²) | Not documented | 40,000 mm/s2 maximum (manufacturer claim)[3][5] |
| Max volumetric flow claimed (mm³/s) | Not documented | <=50 mm3/s (manufacturer claim)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | Planetary-gear direct-drive extruder[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating plate. Brass or hardened-steel nozzles in 0.2/0.4/0.6/0.8/1.0 mm[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | <=350 °C claimed[3][5] |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | Not documented |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass or hardened steel, buyer's choice[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=120 °C claimed; Sovol states the bed is AC-heated[3][5] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided PEI steel plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Eddy-current scanning combined with pressure (force) sensing — Sovol describes it as an inductive sensor plus force sensor[3][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor fitted; type and location not published[3][5] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Allwinner H616, 1 GB RAM, 8 GB eMMC, 64-bit[3] |
| PSU (brand, wattage, rail voltage) | Not documented | 150 W / 24 V (this is the DC supply; the bed is separately AC-heated per Sovol)[3][5] |
| 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 | Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[3][5] |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[1][2] | Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 not supported)[3][5] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera for monitoring; resolution not published[3][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Arrives preassembled[5] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published[3][5] |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[3] |
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.
