Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Centauri Carbon[1]Snapmaker U1 3D Printer[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]$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Variants & sibling models — and how to tell them apart (spec-contamination risk)Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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]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]
Market position: superseded?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Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji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[6]Not documented

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY[1]Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree lead screws with three linear guide rods[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]500 mm/s maximum toolhead speed (manufacturer claim)[2]
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]20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[1]32 mm3/s maximum hotend flow (manufacturer claim)[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaping with an accelerometer, run as a calibration routine[2]
Extrusion Pressure Control

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][4]300 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedStainless steel as standard; hardened steel needed for fibre-filled grades[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature at 25 C ambient[1]100 °C maximum (manufacturer claim)[2]
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]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, auto filament unloading, power-loss recovery and fan self-check; no clog detection on this model (the Centauri Carbon 2 adds it)[1][4]Filament run-out detection, plus air-printing detection and RFID filament recognition[2]

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[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.
