| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon 2 Combo[1] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 9 August 2026 (Shopify publish date)[4] | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] |
| Street price (USD; dated snapshot per entry) | $399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[4] | $649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The Centauri Carbon 2 sold with the CANVAS multicolour unit. Every printing figure matches the bare Centauri Carbon 2; what changes is the body - 500 x 480 x 743 mm and 19.35 kg with CANVAS fitted - and CANVAS capability being listed Yes. Against the first-generation Centauri Carbon: 350 C nozzle rather than 320 C, clog detection added, and a HEPA plus coconut-shell carbon filter stack rather than the nano mineral crystal filter. An ELEGOO x emoji collaboration edition of the same machine is also listed[1][6][7][8] | Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[3][2] |
| Market position: superseded? successor announced? | Not documented | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[9][10] |
| 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] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 743 mm with the CANVAS unit fitted[1] | 505 x 487 x 550 mm[5] |
| Net weight (kg) | 19.35 kg net, 23.8 kg gross[1] | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] |
| Frame construction & material | Integrated die-cast aluminium construction (Centauri Carbon platform)[7] | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed; the Centauri Carbon 2 uses a HEPA plus granulated coconut-shell activated-carbon filter stack rather than the first generation's nano mineral crystal filter, and adds a smart exhaust grille[6][7] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][5] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1] | CoreXY[5] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Dual independent Z motors on 10 mm linear shafts and screws[2] |
| 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] | 600 mm/s (manufacturer claim, tool-head maximum)[5] |
| 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 10000 mm/s2[1] | <=20,000 mm/s2 (manufacturer claim)[5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Direct drive with hardened steel dual gears, 1.75 mm filament[2][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[2][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature - 30 C above the first-generation Centauri Carbon[1][7] | <=370 °C claimed. No firmware max_temp verified for this model[2][5] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[2][5] |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1] | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][5] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling with full-auto calibration[1] | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[1] | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5] |
| Multi-material/multi-color capability or official upgrade path | CANVAS multi-material capability included - the defining difference from the bare Centauri Carbon 2[1] | QIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Auxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[5] |

| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | QIDI claims about 10 minutes from unbox to printing[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed; mechanism not published[5] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, ABS, ASA. Capable: TPU, PC, PA, PET and fibre-reinforced filaments[1] | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[2][5] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 45 dB or less - a manufacturer figure with no distance or method stated, and 10 dB below the first-generation Centauri Carbon's published figure[1][7] | 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[11] | 1-year coverage, 14-day no-reason return, 30-day price protection[2] |
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.
