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]UniFormation GKtwo 10.3" 8K Resin Printer[2][3]
Street price (USD; dated snapshot per entry)Not documented$749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[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]UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm; printing platform 260 x 260 mm[1]228 x 128 x 245 mm[2][3]

Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with one fan[1]Not documented
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]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 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 pathCANVAS 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 documented110/220 V[2][3]
Total rated power draw1100 W at 220 V, 350 W at 110 V rated[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)ELEGOO OS; ElegooSlicer recommended[1]Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[2][3]
Connectivity, UI & Camera
Display: size, type, touch?5-inch colour capacitive touch screen[1]5-inch touchscreen (control panel — not the masking LCD, see W1)[2][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-driveUSB and Wi-Fi[1]USB file transfer[2][3]
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]402.5-405 nm photopolymer resin. No closed compatibility list published[2][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[4]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedPrinting tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[2]
Resin & MSLA
Masking LCDNot documented10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[2][3]
Light sourceNot documentedPhotocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[2][3]
Layer exposure timesNot documented2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[2][3]
Layer height rangeNot documented0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[2][3]
Resin vat & feedingNot documentedResin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[2][3]
Fume extractionNot documentedBuilt-in odour filter[2][3]

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.
