| Property | Prusa CORE One+ (Gen 2)COREXY | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | UniFormation |
| Class | COREXY | RESIN |
| 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] | UniFormation GKtwo 10.3" 8K Resin Printer[3][4] |
| 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[5] | Not documented |
| 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] | $749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[3] |
| 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][6] | UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[3] |
| Market position: superseded? successor announced? | Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[2] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 220 x 270 mm (manufacturer figure)[1] | 228 x 128 x 245 mm[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 415 x 444 x 555 mm (X x Y x Z)[1] | 350 x 315 x 455 mm[3][4] |
| Net weight (kg) | 22.5 kg[1] | 20 kg packaged (UniFormation publishes package weight, not net weight)[3][4] |
| Frame construction & material | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[7] | Not documented |
| 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 MSLA with a UV-blocking cover[3][4] |
| 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] | MSLA — photocuring LCD, single Z axis, straight-lift peel[3][4] |
| Stepper motors (frame size, step angle, brand if known) | 0.9 degree X and Y stepper motors[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic 2130[1] | Not documented |
| 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] | Not documented |
| Gear ratio & drive gear material | 10:1 planetary gearbox[1] | Not documented |
| 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] | Not documented |
| 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][5] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Magnetic heatbed with removable PEI spring-steel sheets; whole-bed heating regardless of object size[1] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| 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 | ||

| 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. 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[8][7] | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[3][4] |

| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Optional in-chamber camera solution (Buddy3D camera bundle listed at $1,237.03 against $1,202.78 for the bare printer)[1][2] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and - as advanced materials in the heated chamber - ABS, ASA, HIPS and PA[1] | 402.5-405 nm photopolymer resin. No closed compatibility list published[3][4] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[9][8] | Not documented |
| 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][7] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[3] |

| Layer exposure times | Not documented | 2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[3][4] |
| Layer height range | Not documented | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[3][4] |
| Resin vat & feeding | Not documented | Resin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[3][4] |

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.
