| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Original Prusa MK4[1] | Sovol SV06 Plus ACE 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 | $299.00 on sovol3d.com against a $349.00 compare-at price, in stock and shipping from US/EU/CA/AU/UK/CN warehouses, checked Aug 2026[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD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[4][1] | Larger sibling of the SV06 ACE ($239, 220x220x250). Differs from the non-ACE SV06 Plus by Z height (350 vs 340 mm), Klipper on an RK3308, ceramic-plate hotend, 4.3-inch capacitive touchscreen and a camera. Notably it has NO power-loss recovery, which the older SV06 did have[2][3][5] |
| Market position: superseded?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[6][4] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 210 x 220 mm (manufacturer figure)[1] | 300 x 300 x 350 mm advertised[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 510 x 575 x 710 mm including screen and filament holder[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] | Open i3-style frame; Sovol publishes no frame-material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame; the Original Prusa Enclosure is an optional add-on[1] | Open frame, no enclosure[2] |
| 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] | Cartesian i3 bedslinger[2] |
| 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 | 500 mm/s maximum (manufacturer claim)[2] |
| Max acceleration (claimed, mm/s²) | Not documented | 15,000 mm/s2 maximum (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 double-gear direct drive, 1:7.5 reduction[2] |
| Gear ratio & drive gear material | 1:10 planetary gearbox[1] | 1:7.5[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-swap nozzle system, 0.4 mm default, other diameters supported[1] | Ceramic heating plate hotend; 0.4 mm nozzle included, 0.6 and 0.8 mm optional[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][7] | <=300 °C claimed[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 100 °C claimed[2] |
| 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 textured PEI 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] | Automatic levelling (Sovol calls the ACE upgrade an added automatic levelling function); probe technology not named on this page[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Built-in Hall-effect filament sensor supporting automatic filament loading[1] | Filament run-out sensor fitted; type and location not published[2] |
| 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 | Rockchip RK3308 ("3308 chip"), 512 MB RAM, 8 GB eMMC[2] |
| PSU (brand, wattage, rail voltage) | 240 W Delta PSU with hardware power panic[1] | 500 W / 24 V, 100-240 VAC 50/60 Hz[2] |
| 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[8][7] | Klipper. Sovol does not publish the fork or version on the product page. OTA updates supported[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 65k-colour graphic screen[1] | 4.3-inch capacitive touchscreen[2] |
| 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] | Wi-Fi 2.4 GHz only, WPA2 only (WPA3 explicitly not supported)[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera, default 640x480, maximum 1280x720 (Sovol writes it as 1080x720P)[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | None. Sovol's own spec table states "Power Loss Recovery: None" for this model[2] |
| 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, PVA[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][8] | 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[9][7] | 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.
