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 Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3]
Release date (announcement and actual shipping)Not documentedAnnounced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[4]
Street price (USD; dated snapshot per entry)Not documented$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)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]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Market position: superseded?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 documentedSuperseded 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[5][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 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][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)500 x 480 x 586 mm with the CANVAS unit fitted[1]505 x 487 x 550 mm[4]
Net weight (kg)15.5 kg net, 19 kg gross[1]32 kg gross (3DJake). QIDI does not publish a net weight on the product page[4]
Frame construction & materialRigid aluminium frame (Centauri 2 platform)[1]Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidNot documentedFully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][4]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY with dual 4260 stepper motors[1]CoreXY[4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree lead screws with three linear guide rods[1]Dual independent Z motors on 10 mm linear shafts and screws[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s or less, recommended 250 mm/s[1]600 mm/s (manufacturer claim, tool-head maximum)[4]
Recommended/typical print speed250 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)[4]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with one fan[1]Direct drive with hardened steel dual gears, 1.75 mm filament[2][4]
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][4]
Max nozzle temp claimed AND firmware max temp limit (both values)350 C claimed max nozzle temperature[1]<=370 °C claimed. No firmware max_temp verified for this model[2][4]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 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][4]
Bed surface (material, texture, coating), single/double-sidedNot documented6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)121-point auto-levelling plus partial bed levelling[1]Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][4]
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 run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[4]

Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedQIDI 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 documentedPower-loss recovery listed; mechanism not published[4]
Materials Support
Officially supported filament listIdeal: PLA, PETG, PLA-CF, TPU. Not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[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][4]
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]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.
