Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Original Prusa MK4[1]Sovol SV06 Plus[2]
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
Variants & sibling models — and how to tell them apart (spec-contamination risk)Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD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[3][1]Larger sibling of the SV06 (220x220x250). Distinct from the SV06 Plus ACE, which is 300x300x350 mm, runs Klipper on an RK3308, adds a 4.3-inch touchscreen, camera and ceramic hotend. The 340 mm vs 350 mm Z figure is the cleanest way to tell the two apart in a spec box[2][4]
Market position: superseded?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[5][3]Delisted by Sovol; the current collection carries the SV06 Plus ACE instead. 3DJake shows it sold out and no longer stocked[6][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 210 x 220 mm (manufacturer figure)[1]300 x 300 x 340 mm advertised (note: the ACE version is 350 mm in Z)[2]
Frame construction & materialDie-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 frame with linear-rail motion, supplied as an assembly kit. One 3DJake purchaser reports construction defects and linear-axis stability problems[2]
Enclosure: open / enclosed; panel material; door/lidOpen 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
Extruder
Type (direct drive / bowden) & design nameNextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[1]Direct-drive extruder, single[2]
Gear ratio & drive gear material1:10 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]Not documented
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]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedMagnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[1]Not documented
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]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Built-in Hall-effect filament sensor supporting automatic filament loading[1]Not documented
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
PSU (brand, wattage, rail voltage)240 W Delta PSU with hardware power panic[1]Not documented
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]Not documented
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-driveEthernet 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]USB connection and mini-SD card[2]
Materials Support
Officially supported filament listPrusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[1]1.75 mm filament; no per-material list published on the listing[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.
