| Property | QIDI X-Smart 3COREXY | Sovol ZeroCOREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | Sovol |
| Class | COREXY | COREXY |
| 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] | Sovol Zero 3D Printer[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] | $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) | 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][6][7] | 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][8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 175 x 180 x 170 mm advertised[1][2] | 152.4 x 152.4 x 152.5 mm advertised[3][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 370 x 362 x 397 mm[1] | 345 x 420 x 475 mm[3] |
| Net weight (kg) | 10.5 kg[1] | Not documented |
| Frame construction & material | QIDI publishes no frame-material breakdown for this model[1] | Full linear rails on all axes; CoreXY with two motors sharing the moving mass[5] |
| Enclosure: open / enclosed; panel material; door/lid | No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[1] | Fully enclosed[5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[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) | <=500 mm/s (manufacturer claim)[1][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) | 20,000 mm/s2 (manufacturer claim)[2] | 40,000 mm/s2 maximum (manufacturer claim)[3][5] |
| Max volumetric flow claimed (mm³/s) | 30 mm3/s extruder flow (manufacturer claim)[1][2] | <=50 mm3/s (manufacturer claim)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive extruder, single, 1.75 mm filament[1][2] | Planetary-gear direct-drive extruder[3] |
| 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] | 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) | <=300 °C claimed[1][2] | <=350 °C claimed[3][5] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Brass[1] | Brass or hardened steel, buyer's choice[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | <=120 °C claimed[1][2] | <=120 °C claimed; Sovol states the bed is AC-heated[3][5] |
| Bed surface (material, texture, coating), single/double-sided | Double-sided flexible magnetic RF plate[1] | Double-sided PEI steel plate[3] |
| 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] | Eddy-current scanning combined with pressure (force) sensing — Sovol describes it as an inductive sensor plus force sensor[3][5] |
| 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] | Filament sensor fitted; type and location not published[3][5] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[1] | 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) | 100-240 VAC, 50/60 Hz[1] | Not documented |
| Total rated power draw | 350 W rated[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[2] | Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[3][5] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch touchscreen[2] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi and USB. No Ethernet listed for this model[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 | Not documented | PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[3] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 1-year coverage (QIDI standard store terms)[9] | 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.
