| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[1][2] | Original Prusa MK4[3] |
| Release date (announcement and actual shipping) | The CORE One+ (Gen 2) refresh was announced on 13 August 2026, on sale immediately, with the first assembled units shipping at once and kits, upgrade kits and individual parts rolling out over the following weeks. It succeeds the CORE One and CORE One+ on the same platform[4] | 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) | $1,202.78 assembled, $925.00 as an assembly kit, on prusa3d.com, Aug 2026. Bundles run to $1,301.85 with camera and advanced filtration. Prusa's own marketing table on the same page quotes "from $1,299" assembled, which does not match the live e-shop price[2][1] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Three generations share the CORE One name: the original CORE One, the CORE One+, and the CORE One+ (Gen 2), with paid upgrade kits between them (CORE One+ to CORE One+ (Gen 2), and an MK4S to CORE One+ (Gen 2) conversion kit). The specifications recorded here are those published on Prusa's current CORE One+ (Gen 2) page and should not be assumed to hold for a first-generation CORE One. The INDX 4-tool and 8-tool machines are variants of the same product page, and the CORE One L is a larger, separate machine[1][2][5] | Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD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[6][3] |
| Market position: superseded? successor announced? | Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[2] | 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[2][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 220 x 270 mm (manufacturer figure)[1] | 250 x 210 x 220 mm (manufacturer figure)[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 415 x 444 x 555 mm (X x Y x Z)[1] | Not documented |
| Net weight (kg) | 22.5 kg[1] | Not documented |
| Frame construction & material | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[7] | 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 a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[1][7] | Open frame; the Original Prusa Enclosure is an optional add-on[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 55 C (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[1] | 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) | 0.9 degree X and Y stepper motors[1] | 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?) | Trinamic 2130[1] | Trinamic TMC2130-LA silent stepper drivers on the xBuddy board[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[1] | 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 | 10:1 planetary gearbox[1] | 1:10 planetary gearbox[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-swap nozzle system; high-flow Prusa brass CHT 0.4 mm nozzle supplied. An optional HT hotend raises the ceiling to 400 C[1] | 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. Prusa's comparison table adds "400 C w/ HT" for the optional HT hotend, which its 13 August 2026 blog post says will only become available in September 2026 - so 400 C is a forthcoming option, not a shipping specification[1][4] | 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][7] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 120 C max heatbed temperature[3] |
| Bed surface (material, texture, coating), single/double-sided | Magnetic heatbed with removable PEI spring-steel sheets; whole-bed heating regardless of object size[1] | 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 with the nozzle as the probe[1] | 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) | Two filament sensors, plus a door sensor and five Semitec thermistors with fan RPM monitoring[1][7] | Built-in Hall-effect filament sensor supporting automatic filament loading[3] |
| Multi-material/multi-color capability or official upgrade path | MMU3 for five filaments, or the INDX system for up to eight, both officially supported[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Custom 32-bit xBuddy board with STM32[1] | Custom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[3] |
| PSU (brand, wattage, rail voltage) | 240 W PSU with hardware power panic[1] | 240 W Delta PSU with hardware power panic[3] |
| Total rated power draw | Power consumption 90 W printing PLA, 110 W printing ABS (manufacturer figures)[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Open-source Prusa Buddy firmware.
