Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Centauri Carbon[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 17 February 2025 (Shopify publish date)[5]Not documented
Street price (USD; dated snapshot per entry)$419.99 on us.elegoo.com, Aug 2026, with the compare-at price also $419.99 (no discount running)[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Variants & sibling models — and how to tell them apart (spec-contamination risk)Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds clog detection, a smart exhaust grille and part-cooling-fan drop detection. The non-carbon Centauri and Centauri 2 are open-frame-oriented machines with a different filament list. Machine size 398 x 404 x 490 mm is shared with the Centauri 2, so body dimensions alone will not identify the model[6][7][1]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][8]
Market position: superseded? successor announced?Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji collaboration edition[9]Not documented

Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s or less, with 250 mm/s given by ELEGOO 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, with a titanium-alloy heat break; a heatbed nozzle wiper cleans it before each print[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)320 C claimed max nozzle temperature (the Centauri Carbon 2 raises this to 350 C)[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 on one face, a PLA-specific surface on the other[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)121-point auto-levelling with full-auto calibration[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor, auto filament unloading, power-loss recovery and fan self-check; no clog detection on this model (the Centauri Carbon 2 adds it)[1][6]Not documented

Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Operating sound published as 55 dB or less - a manufacturer figure with no distance or method stated, so not comparable with an independently measured dB reading[1]Not documented
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[10]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][8]

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.
