| Property | ELEGOO Centauri 2COREXY | Original Prusa MINI+BEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | Prusa Research |
| Class | COREXY | BEDSLINGER |
| 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] | Original Prusa MINI+ Semi-assembled 3D Printer[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[3] | $508.33 on prusa3d.com, Aug 2026[4] |
| 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][5] | Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[2][6] |
| 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] | 180 x 180 x 180 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] | 380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[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] | 4.5 kg without spool holder and external PSU[2] |

| 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] | Bowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[2] |
| Gear ratio & drive gear material | Not documented | 3:1 extruder gearing[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | Not documented |
| 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][5] | 280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | 100 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] | Removable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[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] | SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[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] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Powerful Self-Developed Motherboard" is all ELEGOO publishes[1] | Custom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[2][7] |

| 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[7][8] |
| Connectivity, UI & Camera | ||

| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Semi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[2] |
| 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, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Three thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[2][7] |
| 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[9] | 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] |
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.
