|---|---|---|
| Identity | ||
| Brand | ELEGOO | Prusa Research |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri 2 (page title "Elegoo Centauri 2 | High-Speed CoreXY 3D Printer")[1] | Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[4] | 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] |
| Street price (USD; dated snapshot per entry) | $279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[4] | $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[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Sold both bare and as a Centauri 2 Combo. The Combo is the one with multicolour: 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection are all listed Yes for the Combo and dash for the bare machine, and the Combo body measures 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting, air filter and the smart exhaust grille are optional expansions on both. Distinct from the Centauri Carbon line, which is enclosed and takes carbon-fibre filament[1][6] | 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[2][3][7] |
| Market position: superseded? successor announced? | Not documented | Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm; printing platform 260 x 260 mm[1] | 250 x 220 x 270 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 404 x 490 mm for the bare Centauri 2 (the Combo is 500 x 480 x 586 mm)[1] | 415 x 444 x 555 mm (X x Y x Z)[2] |
| Net weight (kg) | 13.7 kg net, 17.5 kg gross (bare machine; the Combo is 15.5 kg net, 19 kg gross)[1] | 22.5 kg[2] |
| Frame construction & material | Rigid aluminium frame[1] | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[8] |
| Enclosure: open / enclosed; panel material; door/lid | Not documented | Fully enclosed with a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[2][8] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active chamber heating, maximum 55 C (manufacturer figure)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with dual 4260 stepper motors driving X and Y independently[1] | CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Not documented |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 0.9 degree X and Y stepper motors[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[1] | Trinamic 2130[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given as the recommended speed[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[2] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | Quick-swap nozzle system; high-flow Prusa brass CHT 0.4 mm nozzle supplied. An optional HT hotend raises the ceiling to 400 C[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature - higher than the enclosed Centauri Carbon's 320 C, even though ELEGOO lists ABS, ASA, PET, PETG-CF, PA and PC as not recommended on this machine[1][6] | 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[2][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1] | Magnetic heatbed with removable PEI spring-steel sheets; whole-bed heating regardless of object size[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling plus partial bed levelling, with full-auto calibration[1] | Load-cell sensor - fully automatic first-layer calibration with the nozzle as the probe[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto filament unloading, fan self-check, part-cooling-fan drop detection and power-loss recovery[1] | Two filament sensors, plus a door sensor and five Semitec thermistors with fan RPM monitoring[2][8] |
| Multi-material/multi-color capability or official upgrade path | Not documented | MMU3 for five filaments, or the INDX system for up to eight, both officially supported[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Powerful Self-Developed Motherboard" is all ELEGOO publishes[1] | Custom 32-bit xBuddy board with STM32[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W PSU with hardware power panic[2] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1] | Power consumption 90 W printing PLA, 110 W printing ABS (manufacturer figures)[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[1] | 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[9][8] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch colour capacitive touch screen - larger than the 4.3-inch panel on the Centauri Carbon[1][6] | 3.5-inch 65k-colour graphic screen with touch control[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; input formats STL, OBJ, 3MF and STEP[1] | On-device touch UI; remote monitoring and printing through Prusa Connect and the Prusa mobile app; firmware updates from USB, Prusa Connect or the app[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | Ethernet and Wi-Fi (NFC receiver plus an optional Wi-Fi module), USB drive for print files[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | No camera as standard - listed as an optional expansion, as are LED lighting and the air filter[1] | Optional in-chamber camera solution (Buddy3D camera bundle listed at $1,237.03 against $1,202.78 for the bare printer)[2][3] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, PLA-CF, TPU. Explicitly not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and - as advanced materials in the heated chamber - ABS, ASA, HIPS and PA[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[10][9] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[11] | 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[12][8] |
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.
