|---|---|---|

| Brand | Prusa Research | Sovol |
| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[1] | Sovol SV06 Plus ACE 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | $1,199.00 assembled, $899.00 as a kit, for the 10th Anniversary Edition on prusa3d.com, Aug 2026. This is above the price the standard MK3S+ sold at, so do not read it as the MK3S+ street price[1] | $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) | Only the 10th Anniversary Edition remains on sale; the standard MK3S+ is gone from Prusa's printer listing. Two official upgrade paths change the machine substantially and are frequently confused with it: MK3.5 (xBuddy board and new LCD, keeps the MK3 extruder) and MK3.9 (adds the Nextruder). A caution on Prusa's own pages: the "Awards & Press Reviews" paragraph about the MK3S is reproduced verbatim on the MINI+ product page, so award text found on a Prusa page does not necessarily belong to the printer on that page[1][4][5][6] | 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][7] |
| Market position: superseded? successor announced? | Superseded by the MK4/MK4S line. Prusa cut MK3S+ prices at the MK4 launch in March 2023 and said it would keep selling the MK3S+ at a lower price and hold spare parts in stock[5][6] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[1] | 300 x 300 x 350 mm advertised[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[1] | 510 x 575 x 710 mm including screen and filament holder[2] |
| Net weight (kg) | 7 kg (without spool)[1] | Not documented |
| Frame construction & material | Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[5] | 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 separate product[5] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[5] | Cartesian i3 bedslinger[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 500 mm/s maximum (manufacturer claim)[2] |
| Max travel speed | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | Not documented | 15,000 mm/s2 maximum (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with Bondtech gears and an E3D V6 hotend[1] | Planetary double-gear direct drive, 1:7.5 reduction[2] |
| Gear ratio & drive gear material | Not documented | 1:7.5[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | 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 nozzle temperature[1] | <=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 | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[1] | Double-sided textured PEI plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[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) | IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[1] | Filament run-out sensor fitted; type and location not published[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | EINSY RAMBo 8-bit board, co-developed with UltiMachine[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) | Not documented | 500 W / 24 V, 100-240 VAC 50/60 Hz[2] |
| Input voltage (110/220 V, switch or auto) | Custom Delta PSU with hardware-based power panic[1] | Not documented |
| Total rated power draw | Power consumption 80 W on PLA settings, 120 W on ABS settings[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | prusa3d/Prusa-Firmware on GitHub, GPL-3.0, whose README states it is "proudly based on Marlin 1.0.x" and covers the MK3S/MK3/MK2.5S/MK2.5 line; last pushed August 2025.

| 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 | ||

| 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][10] | 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.
