| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon[1] | UltiMaker S7[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 17 February 2025 (Shopify publish date)[3] | 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)[3] | $5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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[4][5][1] | Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[2][6][7] |
| Market position: superseded?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 | Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji collaboration edition[8] | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[7][9] |
| Physical & Frame | ||

| Net weight (kg) | 17.5 kg net, 21 kg gross[1] | Not documented |
| Frame construction & material | Integrated die-cast aluminium construction, which ELEGOO credits for reduced vibration at speed[1] | Fully assembled professional chassis[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a tempered glass door and top cover; a nano mineral crystal air filter, an auxiliary part-cooling fan and a chamber temperature regulator fan are fitted[1] | 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] | 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 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 |
| Max volumetric flow claimed (mm³/s) | 32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[1] | Build speed under 24 mm3/s (manufacturer figure)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Dual extrusion with swappable print cores[2] |
| Filament diameter | Not documented | 2.85 mm[2] |
| 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][4] | Not documented |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | PEI-coated flexible build plate, 20-140 °C[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-coated flexible build plate[2] |
| 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][4] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part cooling plus an auxiliary part-cooling fan and a chamber temperature regulator fan, with real-time fan self-checks[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | ELEGOO describes it only as a "Powerful Self-Developed Motherboard"; no board model or MCU is published[1] | Not documented |

| Materials Support | ||
| Officially supported filament list | Carbon/glass fibre reinforced filaments, PLA, PETG, ABS, ASA, TPU, PET, PC, PA[1] | 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] | Under 50 dBA operating sound, manufacturer figure. No independent measurement[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[10] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[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.
