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]Elegoo Saturn 4 Ultra 16K. Elegoo's product handle is saturn-4-ultra-16k-10inch-monochrome-lcd-resin-3d-printer. 3DJake item number ELG-50.101.038300[2][3]
Street price (USD; dated snapshot per entry)Not documented$649.99 in us.elegoo.com's live Shopify product JSON, in stock, with compare_at_price also $649.99 — no discount active at the time of checking (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]Distinct from the earlier Saturn 4 Ultra (12K); the 16K carries a 15120 x 6230 masking LCD with 14 x 19 um pixels. Elegoo also sells it bundled with a Mercury Plus V2.0 wash/cure station and as a pre-owned SKU, neither of which is the printer-only price[2][3]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY with dual 4260 stepper motors[1]MSLA with tilt-release: the vat tilts to peel each layer rather than pulling straight up. Elegoo claims the mechanism cuts curing time by 25%. Single Z axis, Z precision 0.02 mm[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree lead screws with three linear guide rods[1]Not documented
Speed & Acceleration

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]Not documented
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]Automatic levelling, plus intelligent mechanical sensor alarms[2]
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 documented100-240 V, 50/60 Hz, 24 V 6 A[2]
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]Elegoo EL3D-4.0 system. Slicer is CHITUBOX[2]
Connectivity, UI & Camera
Display: size, type, touch?5-inch colour capacitive touch screen[1]4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[2]
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 and Wi-Fi, with WLAN file transfer[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedAI camera, 1920 x 1080[2]
Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it?Not documentedAI camera with print-failure detection[2]
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]405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[2]
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
Resin & MSLA
Masking LCDNot documented10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[2][3]
Light sourceNot documentedCOB light source with a Fresnel collimating lens[2]
Light uniformity & intensityNot documentedLight energy at the plate quoted as 5 mW/cm2, i.e. 5000 uW/cm2 (manufacturer claim, attributed to the tilt-release and Fresnel optics). No uniformity percentage published and no independent measurement[2]
Vertical print speedmm/hNot documentedUp to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[2]
Release filmNot documentedPFA release film. No rated life published[2]
LCD life & replaceabilityNot documentedMasking LCD shielded by tempered 9H protective glass. Elegoo publishes no rated screen life in hours and does not state user replaceability[2]
Resin vat & feedingNot documentedReplaceable resin vat with a dual pour spout and a drip guard. Heated tank with automatic temperature measurement: Elegoo states resin reaches 25 C in 26 minutes from a 5 C ambient at 50% humidity (manufacturer figure). Capacity not published; no auto-refill[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.
