| 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] | QIDI Plus5, sold as "QIDI Plus5 3D Printer"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Launched 5 August 2026, 09:00 EDT / 15:00 CEST[4] |
| Launch MSRP (USD) | Not documented | $749 regular launch price; a launch-window member discount put it under $700[4] |
| 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] | $749.00 for the standard model on us.qidi3d.com, checked Aug 2026. Other variants: Polar Cooler bundle $899.00, Plus5 Combo $899.00, Combo + Polar Cooler $1,049.00. No compare-at price listed[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][5][6][7] | Four purchase variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), and Combo + Polar Cooler. The Polar Cooler is a pre-sale add-on shipping separately, so its specs are not Plus5 specs. Replaces the Plus4 (305x305x280, 450 W + 400 W chamber)[2][4] |
| Market position: superseded?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 | Superseded by the MK4/MK4S line.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[6][7] | Current flagship of QIDI's large-format line as of Aug 2026; sits below the Max4 (390x390x340)[2][8] |
| 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] | 320 x 320 x 300 mm advertised — QIDI states this is about 18% more volume than the Plus4[2][3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[1] | 500 x 488 x 558 mm[3] |
| Net weight (kg) | 7 kg (without spool)[1] | 29.0 kg net[3] |
| 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[6] | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame; the Original Prusa Enclosure is an optional separate product[6] | Fully enclosed, with a 3-stage air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated, 550 W chamber heater — reported as a 37.5% increase in heater power over the Plus4 (manufacturer claim)[3][4] |
| 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[6] | CoreXY[3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | High-precision linear rails on X[2][4] |
| Belts (type, width, e.g. Gates?) | Not documented | 1.5GT belts, 9 mm wide — wider than the 2GT 6 mm belts common in this class[2][4] |
| 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 | 600 mm/s (manufacturer claim)[3] |
| 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 | <=20,000 mm/s2 (manufacturer claim)[3] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Resonance compensation listed as a feature; implementation not named on the product page[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with Bondtech gears and an E3D V6 hotend[1] | Direct drive with hardened dual gears[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating-plate hotend with a bimetal nozzle; 0.4 mm standard, 0.2/0.6/0.8 mm optional[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=370 °C claimed[2][3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | <=120 °C claimed, described by QIDI as an even-heating bed[2][3] |
| Bed surface (material, texture, coating), single/double-sided | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[1] | Aluminium silicone heated bed with a dual-sided textured PEI plate[3] |
| 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 using an integrated load cell; QIDI describes it as direct nozzle-contact detection[3][4] |
| 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, plus a filament cutter[3] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | 3-in-1 filtration: G3 pre-filter, H12 HEPA, coconut-shell activated carbon; QIDI claims 99.5% capture of airborne particles and dust[2][3][4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | EINSY RAMBo 8-bit board, co-developed with UltiMachine[1] | 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.
