|---|---|---|
| Identity | ||
| Brand | ELEGOO | ELEGOO |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon[1] | ELEGOO Neptune 4 Max[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 17 February 2025 (Shopify publish date)[3] | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[4] |
| 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)[3] | $389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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[5][6][1] | Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[2][7][8][4] |
| Market position: superseded?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 | Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji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 |

| Belts (type, width, e.g. Gates?) | Semi-automatic belt tensioner[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)" is all that is published; no driver part number is given[1] | "Silent Drive (All Axes)"; no driver part number published[10] |
| 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] | 500 mm/s max toolhead speed (manufacturer claim)[2] |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[10] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[1] | 8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[2] |
| Max volumetric flow claimed (mm³/s) | 32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Dual-gear direct extruder with 2 fans[10] |
| 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] | Brass nozzle, 0.4 mm, with a titanium-alloy heat break[10] |
| 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][5] | 300 C claimed max nozzle temperature[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | 85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[2] |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet - textured PEI on one face, a PLA-specific surface on the other[1] | PEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[10] |

| 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] | Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[10] |
| 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[11] | 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[11] |
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.
