| Property | Positron V3.2COREXY | Sovol SV08COREXY |
|---|---|---|
| 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 SV08 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $549.00 on sovol3d.com against a $599.00 compare-at price, in stock, checked Aug 2026 (Canada warehouse quoted as shipping end of September)[2][3] |
| 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] | Sibling SV08 Max is a much larger 500x500x500 machine at $1,099 with a 50 mm3/s flow rate, TMC5160 XY drivers and CAN bus; the SV08 is 30 mm3/s with TMC2209s. Do not carry SV08 Max figures onto the SV08. An eddy-current scanning kit and a 5-inch touchscreen are sold as separate upgrades[3][4][5][2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 350 x 350 x 345 mm advertised[2][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1] | 550 x 537 x 575 mm. Sovol's page says this includes screen and filament holder; 3DJake says it excludes the spool holder[2][5] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 21.5 kg gross (3DJake). Sovol does not publish a net weight[5] |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Aluminium-extrusion CoreXY frame; Sovol states the design is inspired by the Voron 2.4 and that software, firmware and hardware are open source with design files on GitHub, with $2 per unit donated to the Voron project[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Open frame as shipped; Sovol sells an enclosure kit separately (an enclosure-kit package is listed for the SV08 Max)[2][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | CoreXY[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | 700 mm/s maximum (manufacturer claim)[2][5] |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | 40,000 mm/s2 maximum (manufacturer claim)[2][5] |
| Max volumetric flow claimed (mm³/s) | Not documented | <=30 mm3/s (manufacturer claim)[2][5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Planetary-gear direct-drive extruder[2][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | PS plated-copper nozzle, 0.4 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 °C maximum (manufacturer claim)[1] | <=300 °C claimed[2][5] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm included; 0.2, 0.6 and 0.8 mm optional[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Plated copper[1] | Not documented |
| 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] | <=100 °C claimed[2][5] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Powder-coated PEI steel plate[2][5] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Inductive sensor plus a pressure (load) sensor. An eddy-current scanning kit is sold as an upgrade[2][5][3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor fitted, with filament-runout resume; type and location not published[2][5] |
| 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 quad-core Cortex-A53, 1 GB RAM (512 MB + 512 MB), 8 GB eMMC[2][5] |
| PSU (brand, wattage, rail voltage) | DC 24 V, 200 W[1] | Conflicting: Sovol's spec table says 150 W / 24 V, while 3DJake's table gives a rated power of 1000 W at both 110 V and 220 V. The two are only reconcilable if the bed is mains-heated separately from the 24 V logic supply, which Sovol does not state[2][5] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Klipper. Sovol publishes the design files on GitHub and describes software, firmware and hardware as fully open source[2][5] |
| 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 explicitly not supported)[2][5] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Camera listed as fitted by Sovol; 3DJake lists a camera as an accessory. Resolution not published[2][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA and PETG only, per the manufacturer[1] | PLA, PETG, TPU, PETG-CF, ABS and others[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.
