| Property | Original Prusa MK4BEDSLINGER | Sovol ZeroCOREXY |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | Sovol |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Original Prusa MK4[1] | Sovol Zero 3D Printer[2][3] |
| Release date (announcement and actual shipping) | Announced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[1] | Not documented |
| Launch MSRP (USD) | 1099 USD assembled, 799 USD as a kit, VAT included, at launch[1] | Not documented |
| 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| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD MK4-to-MK4S upgrade kit and automatically converted unshipped MK4 orders to the S version. The MK3.5 and MK3.9 upgrades convert an MK3S+ to part of the MK4 electronics stack but are not an MK4[5][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][6] |
| Market position: superseded? successor announced? | Discontinued. No MK4 appears in Prusa's Aug 2026 3D-printer listing, and the MK4 product-page slugs redirect to the MK4S page, so no live first-party price could be recorded[7][5] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 210 x 220 mm (manufacturer figure)[1] | 152.4 x 152.4 x 152.5 mm advertised[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 345 x 420 x 475 mm[2] |
| Frame construction & material | Die-cast aluminium frame - Prusa replaced the MK3S+'s cut-aluminium frame for the MK4, keeping only the Y-axis profiles, some bearings, the heatbed and the power supply[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; the Original Prusa Enclosure is an optional add-on[1] | Fully enclosed[4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[1] | CoreXY[4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails on all axes[4] |
| Stepper motors (frame size, step angle, brand if known) | 400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic TMC2130-LA silent stepper drivers on the xBuddy board[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 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) | Not documented | 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 | Nextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[1] | Planetary-gear direct-drive extruder[2] |
| Gear ratio & drive gear material | 1:10 planetary gearbox[1] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-swap nozzle system, 0.4 mm default, other diameters supported[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) | 300 C claimed max hotend temperature in Prusa's MK4 announcement table - note the MK4S product page publishes 290 C for the same hotend family[1][8] | <=350 °C claimed[2][4] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass or hardened steel, buyer's choice[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | <=120 °C claimed; Sovol states the bed is AC-heated[2][4] |
| Bed surface (material, texture, coating), single/double-sided | Magnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[1] | Double-sided PEI steel plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[1] | 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) | Built-in Hall-effect filament sensor supporting automatic filament loading[1] | Filament sensor fitted; type and location not published[2][4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Custom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[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) | 240 W Delta PSU with hardware power panic[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) | Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[9][8] | 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 65k-colour graphic screen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | On-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Ethernet built in, optional ESP Wi-Fi module delivered with the printer, USB drive; print files can also arrive over LAN or the internet via Prusa Connect[1] | Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 not supported)[2][4] |

| Materials Support | ||
| Officially supported filament list | Prusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[1] | PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | xBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[1][9] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[10][8] | 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.
