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]Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[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]$270.00 on us.phrozen3d.com, backordered with an end-of-September ETA, checked Aug 2026. The collection page rendered it as unavailable on the same day[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]Phrozen's 7.1-inch line is easy to confuse: the Sonic Mini 8K S ($270) sits beside the older Sonic Mini 8K ($340, sold out) and the 5.5-inch Sonic Mini ($129.99). The 10.1-inch Sonic Mighty family is a different size class entirely. The 8K S is the only one of the group with a single linear rail and a lead screw rather than a ball screw[3][2][4][7]
Physical & Frame

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]290 x 290 x 430 mm[2][4]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY with dual 4260 stepper motors driving X and Y independently[1]MSLA, single Z axis on one linear rail with a lead screw, straight-lift peel[2][4]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedOne linear rail; lead screw (not a ball screw)[2][4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree 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 speed250 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 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 - 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 limit110 C max heated bed temperature at 25 C ambient[1]Not documented
Bed surface (material, texture, coating), single/double-sidedDual-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]Not documented
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 documented24 V DC, 2 A[4]
Total rated power draw1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1]48 W maximum system power[4]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[1]Not named by Phrozen. Native file format .PRZ; compatible slicers CHITUBOX, Lychee and VoxelDance Tango[2][4]
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]3.5-inch touch panel (control panel — not the masking LCD, see W1)[4]
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-driveUSB and Wi-Fi[1]USB only[2][4]
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]Not documented
Materials Support
Officially supported filament listIdeal: 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 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[8]Not documented
Resin & MSLA
Masking LCDNot documented7.1-inch 8K monochrome masking LCD, XY pixel pitch 22 um. Phrozen does not publish the pixel count for this model[2][4]
Light sourceNot documentedLinear projection LED module. Wavelength not published for this model[2][4]
Vertical print speedmm/hNot documentedMax 80 mm/h (manufacturer claim). Phrozen does not state the layer height or resin type the figure assumes[4]
Layer height rangeNot documented0.01-0.30 mm[4]
Release filmNot documentedFEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[4][7]

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.
