| Property | ELEGOO Centauri 2COREXY | QIDI i-FastIDEX |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | QIDI |
| Class | COREXY | IDEX |
| 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] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[4] | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | $279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[4] | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[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][5] | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[3][2] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[3][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] | 330 x 250 x 320 mm advertised[2][3] |
| 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] | 710 x 510 x 670 mm[3] |
| Net weight (kg) | 13.7 kg net, 17.5 kg gross (bare machine; the Combo is 15.5 kg net, 19 kg gross)[1] | 33 kg net[3] |
| Frame construction & material | Rigid aluminium frame[1] | Fully assembled enclosed metal-frame machine[2] |
| Enclosure: open / enclosed; panel material; door/lid | Not documented | Fully enclosed with a heated chamber[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with dual 4260 stepper motors driving X and Y independently[1] | Dual independent extruders in an enclosed Cartesian gantry[2][3] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given as the recommended speed[1] | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[3] |
| 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] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| 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] | 350 °C on the high-temperature extruder assembly[2][3] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 110-220 V[3] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1] | 700 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[1] | Not documented |
| 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][5] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; input formats STL, OBJ, 3MF and STEP[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | Wi-Fi, LAN, USB flash drive[2][3] |
| 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] | Not documented |
| 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] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[3] |
| 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[7] | Not documented |
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.
