| 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 MK4[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] | Announced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[3] |
| Launch MSRP (USD) | Not documented | 1099 USD assembled, 799 USD as a kit, VAT included, at launch[3] |
| 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] | Not documented |
| 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 Prusa also sells the unrelated MMU3, which multiplexes five filaments through one nozzle[2][1] | Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD MK4-to-MK4S upgrade kit and automatically converted unshipped MK4 orders to the S version. The MK3.5 and MK3.9 upgrades convert an MK3S+ to part of the MK4 electronics stack but are not an MK4[5][3] |
| Market position: superseded? successor announced? | Not documented | Discontinued. No MK4 appears in Prusa's Aug 2026 3D-printer listing, and the MK4 product-page slugs redirect to the MK4S page, so no live first-party price could be recorded[1][5] |
| 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] | 250 x 210 x 220 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] | Not documented |
| Frame construction & material | Not documented | Die-cast aluminium frame - Prusa replaced the MK3S+'s cut-aluminium frame for the MK4, keeping only the Y-axis profiles, some bearings, the heatbed and the power supply[3] |
| 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 add-on[3] |
| 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 bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[3] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic TMC2130-LA silent stepper drivers on the xBuddy board[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Nextruder direct drive, 10:1 planetary gearbox (shared platform)[2] | Nextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[3] |
| Gear ratio & drive gear material | Not documented | 1:10 planetary gearbox[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Quick-swap nozzle system, 0.4 mm default, other diameters supported[3] |
| 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 hotend temperature in Prusa's MK4 announcement table - note the MK4S product page publishes 290 C for the same hotend family[3][6] |
| 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 | Magnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[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] | Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament sensors fitted (two on the CORE One+ platform)[2] | Built-in Hall-effect filament sensor supporting automatic filament loading[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] | Custom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[3] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W Delta PSU with hardware power panic[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[7][6] | Open-source Prusa Buddy firmware.

| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 65k-colour touch screen (shared platform)[2] | 3.5-inch 65k-colour graphic screen[3] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Not documented | On-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[3] |

| Materials Support | ||
| Officially supported filament list | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA as advanced materials in the heated chamber (shared platform)[2] | Prusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[3] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | xBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[3][7] |
| 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.

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.
