ELEGOO Centauri 2 vs ELEGOO Mars 5 Ultra — documented properties and sources
Property	ELEGOO Centauri 2COREXY	ELEGOO Mars 5 UltraRESIN
Identity
Brand	ELEGOO	ELEGOO
Class	COREXY	RESIN
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)	ELEGOO Centauri 2 (page title "Elegoo Centauri 2 \| High-Speed CoreXY 3D Printer")[1]	ELEGOO Mars 5 Ultra. Elegoo's product handle is mars-5-ultra-9k-7inch-monochrome-lcd-resin-3d-printer[2][3][4]
Release date (announcement and actual shipping)	Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[5]	Not documented
Street price (USD; dated snapshot per entry)	$279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[5]	$269.00 in Elegoo's live US product feed, in stock, checked Aug 2026. The Mars 5 Series collection page rendered $259.00 against a $338.00 compare-at price on the same day, so the two Elegoo surfaces disagree by $10[4][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)	Sold both bare and as a Centauri 2 Combo. The Combo is the one with multicolour: 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection are all listed Yes for the Combo and dash for the bare machine, and the Combo body measures 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting, air filter and the smart exhaust grille are optional expansions on both. Distinct from the Centauri Carbon line, which is enclosed and takes carbon-fibre filament[1][6]	Not a trim of the Mars 5 — a different imaging stack and a different release mechanism: 7-inch 9K LCD and 18 um pixels vs 6.6-inch 4K and 35 um, 150 vs 70 mm/h, tilt-release vs straight lift, an AI camera, and Wi-Fi added. Seven bundle SKUs pair it with Mercury Plus V2.0/V3.0 or Mercury XS at $363-$432[7][2][3][4]
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]	153.36 x 77.76 x 165 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)	398 x 404 x 490 mm for the bare Centauri 2 (the Combo is 500 x 480 x 586 mm)[1]	260 x 268 x 451.5 mm[2]
Net weight (kg)	13.7 kg net, 17.5 kg gross (bare machine; the Combo is 15.5 kg net, 19 kg gross)[1]	Approximately 8.8 kg[2]
Frame construction & material	Rigid aluminium frame[1]	Not documented
Enclosure: open / enclosed; panel material; door/lid	Not documented	Open-frame MSLA with a removable UV-blocking cover[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)	CoreXY with dual 4260 stepper motors driving X and Y independently[1]	MSLA with tilt-release: the resin tank tilts after each layer to peel the part rather than pulling straight up. Single Z axis[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlash	Three lead screws with three linear guide rods[1]	Not documented
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]	Not documented
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 acceleration 10000 mm/s2[1]	Not documented
Extruder
Type (direct drive / bowden) & design name	Dual-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 - higher than the enclosed Centauri Carbon's 320 C, even though ELEGOO lists ABS, ASA, PET, PETG-CF, PA and PC as not recommended on this machine[1][6]	Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit	110 C max heated bed temperature at 25 C ambient[1]	Not documented
Bed surface (material, texture, coating), single/double-sided	Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[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, with full-auto calibration[1]	Automatic levelling, one click, via an intelligent mechanical sensor. One-Click Self-Check routine. Alarms for resin shortage, residue detection and levelling failure[2]
Filament Handling & Detection
Filament runout sensor (type, location)	Filament run-out sensor, clog detection, auto filament unloading, fan self-check, part-cooling-fan drop detection and power-loss recovery[1]	Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)	"Powerful Self-Developed Motherboard" is all ELEGOO publishes[1]	Not documented
Input voltage (110/220 V, switch or auto)	Not documented	100-240 V, 50/60 Hz, 24 V 3 A[2]
Total rated power draw	1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1]	Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)	ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[1]	Not named by Elegoo. Supported slicer is CHITUBOX[2]
Connectivity, UI & Camera
Display: size, type, touch?	5-inch colour capacitive touch screen - larger than the 4.3-inch panel on the Centauri Carbon[1][6]	4.0-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; input formats STL, OBJ, 3MF and STEP[1]	Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-drive	USB and Wi-Fi[1]	USB and Wi-Fi[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)	No camera as standard - listed as an optional expansion, as are LED lighting and the air filter[1]	AI camera fitted; Elegoo does not publish its resolution for this model[2]
Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it?	Not documented	AI camera detects empty build plates and print errors[2]
Materials Support
Officially supported filament list	Ideal: PLA, PETG, PLA-CF, TPU. Explicitly not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[1]	405 nm photopolymer resin. No compatibility list published on this listing[2]
Safety
Firmware safety limits (max temp cutoffs — exact values)	Not documented	Overheating protection activates above 80 °C[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[8]	Not documented
Resin & MSLA
Masking LCD	Not documented	7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[2][4]
Light source	Not documented	25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[2]
Light uniformity & intensity	Not documented	92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[2]
Vertical print speedmm/h	Not documented	150 mm/h maximum, which Elegoo attributes to the tilt-release mechanism (manufacturer claim). Elegoo also offers switchable slow and fast print modes but does not state the layer height the figure assumes[2]
Layer exposure times	Not documented	1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[2]
LCD life & replaceability	Not documented	Masking LCD protected by a scratch-resistant tempered 9H glass cover that also guards against resin leakage. Elegoo publishes no rated screen life in hours and does not state whether the user can replace the LCD[2]
Resin vat & feeding	Not documented	Resin tank supplied with the machine; resin-shortage and residue-detection alarms fitted. 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.
