| Property | Prusa CORE One+ (Gen 2) INDXTOOLCHANGER | Original Prusa i3 MK3S+BEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | Prusa Research |
| Class | TOOLCHANGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[1][2] | Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[3] |
| Release date (announcement and actual shipping) | Announced as shipping on 20 August 2026 ("INDX, Shipping Has Started, Complete Printers Open for Orders"). Prusa's own front page in Aug 2026 announces "Prusa CORE One+ (Gen 2) INDX, Shipping Has Started, Complete Printers Open for Orders", with the assembled 8-tool machine quoted as shipping from 15 October and the kit from 29 October[4][1] | Not documented |
| Street price (USD; dated snapshot per entry) | $1,850.93 for the INDX 4-Tool and $2,082.41 for the INDX 8-Tool on prusa3d.com, Aug 2026; the 8-Tool assembly kit is $1,804.63. Camera and filtration bundles run to $2,152.78[1][2] | $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[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | INDX is a multi-tool option on the CORE One+ (Gen 2) product page rather than a separate printer, sold in 4-tool and 8-tool configurations, plus a CORE One/+ INDX conversion kit for existing machines. All of the body, hotend, bed and electronics figures below come from that shared CORE One+ (Gen 2) page and were not published separately for the INDX machine, so treat them as platform figures. Prusa also sells the unrelated MMU3, which multiplexes five filaments through one nozzle[2][1] | 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[3][5][6][1] |
| Market position: superseded? successor announced? | Not documented | 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][1] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 220 x 270 mm - the CORE One+ (Gen 2) figure from the shared product page; Prusa does not publish a separate INDX build volume[2] | 25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[2] | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[3] |
| Net weight (kg) | Not documented | 7 kg (without spool)[3] |
| Frame construction & material | Not documented | 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] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with active chamber heating up to 55 C (shared CORE One+ platform)[2] | Open frame; the Original Prusa Enclosure is an optional separate product[6] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[2] | 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] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[3] |
| Speed & Acceleration | ||
| Max travel speed | Not documented | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Nextruder direct drive, 10:1 planetary gearbox (shared platform)[2] | Direct drive with Bondtech gears and an E3D V6 hotend[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 290 C claimed max nozzle temperature, 400 C with the optional HT hotend (shared platform)[2] | 300 C claimed max nozzle temperature[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature (shared platform)[2] | 120 C max heatbed temperature[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Load-cell sensor, fully automatic first-layer calibration (shared platform)[2] | SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament sensors fitted (two on the CORE One+ platform)[2] | IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[3] |
| Multi-material/multi-color capability or official upgrade path | INDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[2] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Custom 32-bit xBuddy board with STM32 (shared platform)[2] | EINSY RAMBo 8-bit board, co-developed with UltiMachine[3] |
| Input voltage (110/220 V, switch or auto) | Not documented | Custom Delta PSU with hardware-based power panic[3] |
| Total rated power draw | Not documented | Power consumption 80 W on PLA settings, 120 W on ABS settings[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Open-source Prusa Buddy firmware.

Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[7][8] | 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] |

| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | 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[6][9] |
| 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][8] | 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.

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.
