| Property | ELEGOO Centauri 2 ComboCOREXY | 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 Combo - the Centauri 2 sold with the CANVAS multicolour unit[1] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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) | Same printer as the bare Centauri 2 for every motion, hotend, bed and electronics figure; what the Combo adds is 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection, and what it costs is bench space - 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting and air filter remain optional expansions on both[1] | 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| Market position: superseded?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][4] |
| 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) | 500 x 480 x 586 mm with the CANVAS unit fitted[1] | 710 x 510 x 670 mm[3] |
| Net weight (kg) | 15.5 kg net, 19 kg gross[1] | 33 kg net[3] |
| Frame construction & material | Rigid aluminium frame (Centauri 2 platform)[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[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 |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, recommended 250 mm/s[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[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default 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[1] | 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 |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling plus partial bed levelling[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto tangle detection, RFID filament detection, auto refill, auto filament unloading and power-loss recovery[1] | Not documented |
| Multi-material/multi-color capability or official upgrade path | CANVAS four-colour printing with RFID filament identification and automatic refill - the defining difference from the bare Centauri 2[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Powerful Self-Developed Motherboard"[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[1] | 700 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended[1] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch colour capacitive touch screen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; STL, OBJ, 3MF and STEP input[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] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, PLA-CF, TPU. 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[5] | 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.
