| Class | BEDSLINGER | COREXY |
| 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] | VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[2] |
| 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] | $1,360.00 at Mellow, available and shipping from China, checked Aug 2026[2] |
| 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][3][4][5] | Ordered by colour (black or silver) and mains voltage (110 V or 220 V). Mellow describes the kit as a test version that still requires the buyer to print some components, and the 5-inch DSI screen requires a host computer that supports DSI — neither is included[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| Market position: superseded?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 | Superseded by the MK4/MK4S line.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[4][5] | 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] | 330 x 330 x 400 mm[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] | 530 x 500 x 720 mm body dimensions[2] |
| Net weight (kg) | 7 kg (without spool)[1] | 31 kg net, 36 kg gross[2] |
| 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[4] | CNC-machined all-metal frame with carbon-rod components[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame; the Original Prusa Enclosure is an optional separate product[4] | Not documented |
| 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[4] | CoreXY in an AWD (all-wheel drive) arrangement — two motors on X and two on Y, four in total for the XY plane, each on its own external driver[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | LDO 9 mm rail on X; LDO 12 mm dual rails on Y; 10 mm optical shafts on Z[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] | Four external TMC5160 drivers for the LDO XY motors[2] |
| Speed & Acceleration | ||
| Max travel speed | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with Bondtech gears and an E3D V6 hotend[1] | Lightweight all-metal direct drive with a twill drive wheel[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | VZ High Speed hotend[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 120 °C maximum bed temperature (manufacturer claim)[2] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 750 W silicone bed heater on an 8 mm aluminium plate[2] |
| Bed surface (material, texture, coating), single/double-sided | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[1] | 8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[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] | Not documented |
| 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] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | EINSY RAMBo 8-bit board, co-developed with UltiMachine[1] | 32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[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. Updated over USB from a PC[6] | Klipper or RepRapFirmware[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch DSI display; requires a compatible host computer, which is not included[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[1] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; some parts must be printed by the buyer[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, carbon-filled, woodfill and other filled materials[1] | Not documented |
| 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[4][6] | 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[7][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.
