Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab P2S; spec sheet header "P2S Spec Sheet"[1]ELEGOO Centauri Carbon[2]
Release date (announcement and actual shipping)Not documentedListed on the ELEGOO US store from 17 February 2025 (Shopify publish date)[3]
Street price (USD; dated snapshot per entry)From $549.00 on the Bambu Lab US store, Aug 2026; the product page shows $749.00 with the P2S Combo variant selected[4][5]$419.99 on us.elegoo.com, Aug 2026, with the compare-at price also $419.99 (no discount running)[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two SKUs: P2S and P2S Combo (with the 2nd-generation AMS, which adds filament drying). Do not carry P1S figures across - the P2S differs on nearly every headline number: 600 vs 500 mm/s, 110 vs 100 C bed, hardened-steel vs stainless nozzle, 5-inch 854x480 touchscreen vs 2.7-inch monochrome, 14.9 vs 12.95 kg, 1920x1080 30 fps camera vs 1280x720 at 0.5 fps[1][6]Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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[7][8][2]
Market position: superseded? successor announced?Current model, marketed by Bambu as "The Classic Evolves" - the direct replacement for the P1S, which is still sold below it[4]Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji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]

Machine footprint (mm) & clearance needed (cable/spool overhang)392 x 406 x 478 mm[1]398 x 404 x 490 mm[2]
Net weight (kg)14.9 kg net[1]17.5 kg net, 21 kg gross[2]
Frame construction & materialPlastic and steel chassis with a plastic and glass outer frame[1]Integrated die-cast aluminium construction, which ELEGOO credits for reduced vibration at speed[2]

No active chamber heater is listed[1]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[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY - Bambu positions the P2S as the successor to the P1S platform. The spec sheet itself does not name the kinematics[1][5]CoreXY[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedThree lead screws with three linear guide rods[2]
Belts (type, width, e.g. Gates?)Not documentedSemi-automatic belt tensioner[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)" is all that is published; no driver part number is given[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]500 mm/s or less, with 250 mm/s given by ELEGOO as the recommended speed[2]
Recommended/typical print speedNot documented250 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[2]
Max volumetric flow claimed (mm³/s)40 mm3/s standard-flow hotend, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1]32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel extruder gears, driven by a Bambu Lab high-precision permanent-magnet synchronous motor rather than a plain stepper; built-in filament cutter[1]Dual-gear direct extruder with one fan[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported[1]Brass-hardened steel nozzle, 0.4 mm, with a titanium-alloy heat break; a heatbed nozzle wiper cleans it before each print[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]320 C claimed max nozzle temperature (the Centauri Carbon 2 raises this to 350 C)[2][7]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heatbed temperature[1]110 C max heated bed temperature at 25 C ambient[2]
Bed surface (material, texture, coating), single/double-sidedFlexible steel plate; Textured PEI plate included, Smooth PEI Plate and Cool Plate SuperTack supported[1]Dual-sided spring steel sheet - textured PEI on one face, a PLA-specific surface on the other[2]

Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, tangle sensor, door sensor; filament odometry with AMS[1]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)[2][7]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan, hotend cooling fan and auxiliary part-cooling fan, all closed-loop controlled[1]Part cooling plus an auxiliary part-cooling fan and a chamber temperature regulator fan, with real-time fan self-checks[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Motion controller is a dual-core Cortex-M4 plus a single-core Cortex-M7; application processor is a quad-core 1.5 GHz ARM A7 with a 2 TOPS neural processing unit. Board model and chip markings not published[1]ELEGOO describes it only as a "Powerful Self-Developed Motherboard"; no board model or MCU is published[2]
Total rated power draw100-120 VAC / 200-240 VAC 50/60 Hz; max 1200 W at 220 V, 1000 W at 110 V; steady state 200 W printing PLA[1]1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[10]ELEGOO OS with OTA updates; 8 GB of on-board storage. ElegooSlicer recommended, with Orca and Cura supported[2]

On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus mobile app and PC app; Bambu markets on-device AI error detection[1]Colour touch UI; LED chamber lighting fitted; OTA firmware updates[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi (802.11 a/b/g/n, 2.4 and 5 GHz), built-in 8 GB eMMC and a USB port. Ethernet not available; no network kill switch and no 802.1X[1]USB and dual-band Wi-Fi for LAN transfers[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in camera, 1920x1080 at 30 fps - a real video-rate camera, unlike the 0.5 fps unit in the P1 series[1][6]Chamber camera fitted, with real-time monitoring and time-lapse; dual built-in LED strips[2]
Materials Support
Officially supported filament listPLA, PETG, ABS, ASA, TPU, support materials, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[1]Carbon/glass fibre reinforced filaments, PLA, PETG, ABS, ASA, TPU, PET, PC, PA[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating 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[2]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[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[12]

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.
