| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon 2 Combo[1] | Snapmaker U1 3D Printer[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 9 August 2026 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[3] | $849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The Centauri Carbon 2 sold with the CANVAS multicolour unit. Every printing figure matches the bare Centauri Carbon 2; what changes is the body - 500 x 480 x 743 mm and 19.35 kg with CANVAS fitted - and CANVAS capability being listed Yes. Against the first-generation Centauri Carbon: 350 C nozzle rather than 320 C, clog detection added, and a HEPA plus coconut-shell carbon filter stack rather than the nano mineral crystal filter. An ELEGOO x emoji collaboration edition of the same machine is also listed[1][4][5][6] | An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm; printing platform 260 x 260 mm[1] | 270 x 270 x 270 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 743 mm with the CANVAS unit fitted[1] | 584 x 499 x 730 mm[2] |
| Net weight (kg) | 19.35 kg net, 23.8 kg gross[1] | 18.2 kg[2] |
| Frame construction & material | Integrated die-cast aluminium construction (Centauri Carbon platform)[5] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed; the Centauri Carbon 2 uses a HEPA plus granulated coconut-shell activated-carbon filter stack rather than the first generation's nano mineral crystal filter, and adds a smart exhaust grille[4][5] | Open as sold; a top cover is an optional accessory that raises the supported material range[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1] | Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2] |

| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given as the recommended speed[1] | 500 mm/s maximum toolhead speed (manufacturer claim)[2] |
| 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 10000 mm/s2[1] | 20,000 mm/s2 maximum (manufacturer claim)[2] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s maximum hotend flow (manufacturer claim)[2] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input shaping with an accelerometer, run as a calibration routine[2] |
| Extrusion Pressure Control | ||
| Pressure advance (Klipper) / linear advance (Marlin) supported? | Not documented | Pressure advance, with automatic flow compensation calibration[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-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 - 30 C above the first-generation Centauri Carbon[1][5] | 300 °C maximum (manufacturer claim)[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Stainless steel as standard; hardened steel needed for fibre-filled grades[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | 100 °C maximum (manufacturer claim)[2] |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1] | Flexible steel sheet with a PEI surface[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] | Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[1] | Filament run-out detection, plus air-printing detection and RFID filament recognition[2] |
| Multi-material/multi-color capability or official upgrade path | CANVAS multi-material capability included - the defining difference from the bare Centauri Carbon 2[1] | Four toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Main plus auxiliary part-cooling fans[2] |
| Electronics & Power | ||

| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Camera fitted[1] | 2 MP built-in chamber camera for live view[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published[2] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, ABS, ASA. Capable: TPU, PC, PA, PET and fibre-reinforced filaments[1] | Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 45 dB or less - a manufacturer figure with no distance or method stated, and 10 dB below the first-generation Centauri Carbon's published figure[1][5] | 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[7] | Not documented |
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.
