| Brand | ELEGOO | QIDI |
| Class | COREXY | COREXY |
| 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 X-Smart 3, listed in QIDI navigation as X-Smart3[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published by QIDI on the pages checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[3] |
| 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] | Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][4][5] |
| 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] | 175 x 180 x 170 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 586 mm with the CANVAS unit fitted[1] | 370 x 362 x 397 mm[2] |
| Net weight (kg) | 15.5 kg net, 19 kg gross[1] | 10.5 kg[2] |
| Frame construction & material | Rigid aluminium frame (Centauri 2 platform)[1] | QIDI publishes no frame-material breakdown for this model[2] |
| Enclosure: open / enclosed; panel material; door/lid | Not documented | No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with dual 4260 stepper motors[1] | CoreXY[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] | <=500 mm/s (manufacturer claim)[2][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] | 20,000 mm/s2 (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | Not documented | 30 mm3/s extruder flow (manufacturer claim)[2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Direct-drive extruder, single, 1.75 mm filament[2][3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | <=300 °C claimed[2][3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | <=120 °C claimed[2][3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided flexible magnetic RF plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling plus partial bed levelling[1] | 16-point automatic bed levelling per QIDI's US page; probe technology not named[3] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 16 points (QIDI's US page). Not verified against firmware[3] |
| 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] | Filament detection fitted; type and location not published[2] |
| 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 |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[2] |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[2] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated[1] | 350 W rated[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended[1] | Klipper[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch colour capacitive touch screen[1] | 4.3-inch touchscreen[3] |
| 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 and USB. No Ethernet listed for this model[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] | Not documented |
| 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[6] | 1-year coverage (QIDI standard store terms)[7] |
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.
