| 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] | QIDI Q1 Pro, listed by QIDI as "Q1 Pro 3D Printer". QIDI traded as Qidi Tech until end-2024[2] |
| Release date (announcement and actual shipping) | Not documented | Not stated on QIDI's own product page; the page now carries a discontinuation notice instead of a launch date (checked Aug 2026)[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] | $499.00 on both qidi3d.com and us.qidi3d.com, checked Aug 2026 — but the listing is marked Sold Out and the page states "This model has been discontinued". qidi3d.com shows it against a $599.00 regular price; the US store shows compare-at $499.00[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] | Succeeded by the QIDI Q2, which QIDI's own comparison on the Q1 Pro page distinguishes as 270x270x256 mm (vs 245x245x240), 370 °C hotend (vs 350 °C) and 65 °C chamber (vs 60 °C). Do not read Q2 figures onto the Q1 Pro[2][3] |
| Market position: superseded?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 | Superseded by the MK4/MK4S line.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] | Discontinued and out of production; QIDI states spare parts and support for existing owners remain available. Replaced by the Q2[2][3] |
| 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] | 245 x 245 x 240 mm advertised (QIDI). No independently measured usable envelope found[2][7] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[1] | 477 x 467 x 489 mm machine dimensions (QIDI)[2][7] |
| Net weight (kg) | 7 kg (without spool)[1] | 17 kg net, 20.3 kg gross (QIDI). 3DJake lists the 20.3 kg figure as gross weight[2][7] |
| 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] | Metal CoreXY motion frame with panelled enclosure; QIDI publishes no frame-material breakdown for this model[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame; the Original Prusa Enclosure is an optional separate product[5] | Fully enclosed with independent chamber heating to 60 °C; QIDI does not publish the panel materials for this model[2][7] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 60 °C, actively heated (manufacturer claim — this is a heater setpoint, not a measured passive figure)[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[7] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | 10 mm linear steel rods with automatically tensioned belt (manufacturer description)[7] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Independent dual Z lead-screw motors[7] |
| 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, worded by QIDI as maximum tool-head speed (manufacturer claim, not a sustained printing speed)[2][7] |
| 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)[2][7] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with Bondtech gears and an E3D V6 hotend[1] | Direct-drive extruder with hardened steel gears[2][7] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Tri-metal hotend with a ceramic heater plate and a bimetal nozzle, 0.4 mm standard[2][7] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=350 °C claimed. No firmware max_temp verified for this model[2][7] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | <=120 °C claimed. No firmware limit verified for this model[2][7] |
| 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 on an aluminium substrate bed[2][7] |
| 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; QIDI markets it as "hands-free automatic levelling" with dual sensors, without naming the probe technology[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; QIDI also lists filament tangle detection without describing the mechanism[7] |
| Cooling & Air Handling | ||

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.
