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 SV08 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]$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)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]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][7][8][2]
Market position: superseded?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Superseded by the MK4/MK4S line.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 usable25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[1]350 x 350 x 345 mm advertised[2][8]
Machine footprint (mm) & clearance needed (cable/spool overhang)500 x 550 x 400 mm (X x Y x Z), without the spool holder[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][8]
Net weight (kg)7 kg (without spool)[1]21.5 kg gross (3DJake). Sovol does not publish a net weight[8]
Frame construction & materialCut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[5]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/lidOpen frame; the Original Prusa Enclosure is an optional separate product[5]Open frame as shipped; Sovol sells an enclosure kit separately (an enclosure-kit package is listed for the SV08 Max)[2][7]
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]CoreXY[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]TMC2209[2]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented700 mm/s maximum (manufacturer claim)[2][8]
Max travel speed"200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[1]Not documented
Max acceleration (claimed, mm/s²)Not documented40,000 mm/s2 maximum (manufacturer claim)[2][8]
Max volumetric flow claimed (mm³/s)Not documented<=30 mm3/s (manufacturer claim)[2][8]
Extruder
Type (direct drive / bowden) & design nameDirect drive with Bondtech gears and an E3D V6 hotend[1]Planetary-gear direct-drive extruder[2][8]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]<=300 °C claimed[2][8]
Stock nozzle size & sizes included in boxNot documented0.4 mm included; 0.2, 0.6 and 0.8 mm optional[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]<=100 °C claimed[2][8]
Bed surface (material, texture, coating), single/double-sidedRemovable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[1]Powder-coated PEI steel plate[2][8]
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]Inductive sensor plus a pressure (load) sensor. An eddy-current scanning kit is sold as an upgrade[2][8][3]
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 sensor fitted, with filament-runout resume; type and location not published[2][8]
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 LinuxNot documentedAllwinner H616 quad-core Cortex-A53, 1 GB RAM (512 MB + 512 MB), 8 GB eMMC[2][8]
PSU (brand, wattage, rail voltage)Not documentedConflicting: 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][8]
Input voltage (110/220 V, switch or auto)Custom Delta PSU with hardware-based power panic[1]Not documented
Total rated power drawPower 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. Updated over USB from a PC[9]Klipper. Sovol publishes the design files on GitHub and describes software, firmware and hardware as fully open source[2][8]
Connectivity, UI & Camera
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveSD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[1]Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 explicitly not supported)[2][8]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedCamera listed as fitted by Sovol; 3DJake lists a camera as an accessory. Resolution not published[2][8]
Materials Support
Officially supported filament listPLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, carbon-filled, woodfill and other filled materials[1]PLA, PETG, TPU, PETG-CF, ABS and others[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Prusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[5][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][11]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.
