| Property | Positron V3.2COREXY | Sovol ZeroCOREXY |
|---|---|---|
| Identity | ||
| Brand | Positron3D | Sovol |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[1] | Sovol Zero 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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[2][3][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[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[2][4][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 152.4 x 152.4 x 152.5 mm advertised[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1] | 345 x 420 x 475 mm[2] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | Not documented |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Full linear rails on all axes; CoreXY with two motors sharing the moving mass[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Fully enclosed[4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | CoreXY[4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails on all axes[4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | 1200 mm/s maximum (manufacturer claim). Sovol's own material acknowledges 700 mm/s as the realistic figure for detailed prints[2][4] |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | 40,000 mm/s2 maximum (manufacturer claim)[2][4] |
| Max volumetric flow claimed (mm³/s) | Not documented | <=50 mm3/s (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Planetary-gear direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | PS plated-copper nozzle, 0.4 mm[1] | Ceramic heating plate. Brass or hardened-steel nozzles in 0.2/0.4/0.6/0.8/1.0 mm[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 °C maximum (manufacturer claim)[1] | <=350 °C claimed[2][4] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Plated copper[1] | Brass or hardened steel, buyer's choice[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[1] | <=120 °C claimed; Sovol states the bed is AC-heated[2][4] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Double-sided PEI steel plate[2] |
| 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[2][4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor fitted; type and location not published[2][4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | LDO Positron mainboard[1] | Not documented |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Allwinner H616, 1 GB RAM, 8 GB eMMC, 64-bit[2] |
| PSU (brand, wattage, rail voltage) | DC 24 V, 200 W[1] | 150 W / 24 V (this is the DC supply; the bed is separately AC-heated per Sovol)[2][4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[2][4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 not supported)[2][4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera for monitoring; resolution not published[2][4] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | Arrives preassembled[4] |
| 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[2][4] |
| Materials Support | ||
| Officially supported filament list | PLA and PETG only, per the manufacturer[1] | PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[2] |
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.
