| Class | COREXY | COREXY |
| 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 Carbon[2] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 17 February 2025 (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] | $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) | 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distinct from the 2026 P2S, which is a different machine (600 mm/s, 110 C bed, 5-inch touchscreen, 14.9 kg)[1][5] | Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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[6][7][2] |
| Market position: superseded?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in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[4][8] | Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji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] |
| 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[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] | 17.5 kg net, 21 kg gross[2] |
| Frame construction & material | Steel chassis (shared with the P1P) inside plastic and glass panels[1] | Integrated die-cast aluminium construction, which ELEGOO credits for reduced vibration at speed[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] | 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 driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[10] | CoreXY[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[10] | Three lead screws with three linear guide rods[2] |
| Belts (type, width, e.g. Gates?) | Rear adjustable belt tensioners with a Belt Tension Monitor[10] | Semi-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) | 500 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 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] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[10] | 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][10] | 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 hot-end temperature[1] | 320 C claimed max nozzle temperature (the Centauri Carbon 2 raises this to 350 C)[2][6] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max build-plate temperature[1] | 110 C max heated bed temperature at 25 C ambient[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1] | Dual-sided spring steel sheet - textured PEI on one face, a PLA-specific surface on the other[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Nozzle-touch probing using three ceramic force (piezo) sensors mounted under the heatbed - Z homing is done by detecting the force of the nozzle contacting the bed[11][10] | 121-point auto-levelling with full-auto calibration[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - filament run-out sensor[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][6] |

| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Chamber temperature regulator fan with an activated-carbon air filter[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | ELEGOO describes it only as a "Powerful Self-Developed Motherboard"; no board model or MCU is published[2] |
| Total rated power draw | 100-240 VAC 50/60 Hz; 1000 W at 220 V, 350 W at 110 V[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[12] | ELEGOO OS with OTA updates; 8 GB of on-board storage. ElegooSlicer recommended, with 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)[10] | 4.3-inch colour capacitive touch screen[2] |
| 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[10] | Colour touch UI; LED chamber lighting fitted; OTA firmware updates[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, Bluetooth and Bambu-Bus, microSD card storage, 5 V/1.5 A USB output power (P1 series)[10] | USB and dual-band Wi-Fi for LAN transfers[2] |

| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[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 documented | 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[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[13] | 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[14] |
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.
