| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[1] | ELEGOO Centauri 2 (page title "Elegoo Centauri 2 | High-Speed CoreXY 3D Printer")[2] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 24 June 2026 (Shopify publish date)[3] |
| Street price (USD; dated snapshot per entry) | From $369.00 (base P1S) on the Bambu Lab US store, Aug 2026, against a stated typical price of $399.00; with the P1S AMS 2 Pro Combo variant selected the same page shows $539.00 against a typical $579.00[4][1] | $279.00 on us.elegoo.com, Aug 2026, against a compare-at price of $299.00[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Enclosed version of the P1P and mechanically the same motion platform. Three SKUs on one product page: P1S, P1S AMS Combo and P1S AMS 2 Pro Combo (the AMS 2 Pro adds active filament drying). Sibling figures that get mixed up: net weight 12.95 kg (P1S) vs 9.65 kg (P1P); depth 389 mm vs 386 mm; ABS/ASA Ideal (P1S) vs Capable (P1P). Also distinct from the 2026 P2S, which is a different machine (600 mm/s, 110 C bed, 5-inch touchscreen, 14.9 kg)[1][5] | Sold both bare and as a Centauri 2 Combo. The Combo is the one with multicolour: 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection are all listed Yes for the Combo and dash for the bare machine, and the Combo body measures 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting, air filter and the smart exhaust grille are optional expansions on both. Distinct from the Centauri Carbon line, which is enclosed and takes carbon-fibre filament[2][6] |
| Market position: superseded? successor announced? | Still sold in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[4][7] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm advertised. Bambu's own footnote sets the default printable height in Bambu Studio to 250 mm to prevent heatbed collisions, and notes the collapsible filament-cutter stopper occupies part of the print area when popped out[1] | 256 x 256 x 256 mm; printing platform 260 x 260 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 389 x 389 x 458 mm; package 485 x 480 x 530 mm[1] | 398 x 404 x 490 mm for the bare Centauri 2 (the Combo is 500 x 480 x 586 mm)[2] |
| Net weight (kg) | 12.95 kg net, 17.60 kg gross; the AMS Combo ships at 21.60 kg gross and the AMS 2 Pro Combo at 21 kg gross[1] | 13.7 kg net, 17.5 kg gross (bare machine; the Combo is 15.5 kg net, 19 kg gross)[2] |
| Frame construction & material | Steel chassis (shared with the P1P) inside plastic and glass panels[1] | Rigid aluminium frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed - plastic and glass panels with a glass front door and lid, plus an activated-carbon air filter. No active chamber heater; the chamber temperature regulator fan is closed-loop controlled[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[8] | CoreXY with dual 4260 stepper motors driving X and Y independently[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three leadscrews belt-driven from a single stepper motor, whole bed moving in Z; manual tramming by three knobs under the bed, no motorised Z-tilt[8] | Three lead screws with three linear guide rods[2] |
| Belts (type, width, e.g. Gates?) | Rear adjustable belt tensioners with a Belt Tension Monitor[8] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)"; no driver part number published[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 500 mm/s or less, with 250 mm/s given as the recommended speed[2] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[8] | Dual-gear direct extruder with one fan[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal all-in-one hotend with the nozzle integrated into the heatblock, replaced as a unit; 0.4 mm stainless-steel nozzle included, 0.2/0.6/0.8 mm optional[1][8] | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 350 C claimed max nozzle temperature - higher than the enclosed Centauri Carbon's 320 C, even though ELEGOO lists ABS, ASA, PET, PETG-CF, PA and PC as not recommended on this machine[2][6] |
| Heated Bed & Surface | ||

| 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; ElegooSlicer recommended, Orca and Cura supported[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 2.7-inch 192x64 monochrome screen, not a touchscreen; control by button, app or PC application (P1 series)[8] | 5-inch colour capacitive touch screen - larger than the 4.3-inch panel on the Centauri Carbon[2][6] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Button-driven monochrome on-device UI; job setup happens in Bambu Studio or Bambu Handy[8] | Colour touch UI; input formats STL, OBJ, 3MF and STEP[2] |

| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[1] | Ideal: PLA, PETG, PLA-CF, TPU. Explicitly not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[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.
