ELEGOO Centauri 2 vs QIDI Max4 — documented properties and sources
Property	ELEGOO Centauri 2COREXY	QIDI Max4COREXY
Identity
Brand	ELEGOO	QIDI
Class	COREXY	COREXY
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]	QIDI Max4, sold as "Max4 High-Temp 3D Printer"[2][3]
Release date (announcement and actual shipping)	Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[4]	Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][5]
Street price (USD; dated snapshot per entry)	$279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[4]	$1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[2]
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]	Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[2][5]

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, lifetime tech guidance, 14-day no-reason return[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.
