| Brand | Bambu Lab | ELEGOO |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab P1P. Bambu documents it alongside the P1S in a single two-column parameters table[1] | ELEGOO Neptune 4 Max[2] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[3] |
| Street price (USD; dated snapshot per entry) | Not documented | $389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | P1P is the open-frame version; the P1S is the same motion platform in an enclosure with plastic and glass panels. Bambu's own comparison table shows what the P1P lacks: control-board fan, chamber temperature regulator fan, auxiliary part-cooling fan and air filter are all listed "Optional" on the P1P and "Closed Loop Control"/"Activated Carbon Filter" on the P1S. The P1P is also lighter, 9.65 kg vs 12.95 kg, and 386 mm deep vs 389 mm. A P1P Enclosure Kit is sold as a spare part. Filament support differs accordingly: ABS/ASA are "Capable" on the P1P but "Ideal" on the P1S[1] | Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[2][4][5][3] |
| Market position: superseded? successor announced? | Superseded. No longer listed in the Bambu Lab US store 3D-printer collection in Aug 2026 (the collection carries A1, A1 mini, A2L, P1S, P2S, X2D, H2S, H2D, H2C); /products/p1p redirects to the collection page and only P1P spare parts remain in the store sitemap. No live first-party price could therefore be recorded[6][1] | 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 limits the default printable height in Bambu Studio to 250 mm to avoid heatbed collisions, and warns that the collapsible filament-cutter stopper takes part of the printing area when popped out[1] | 420 x 420 x 480 mm; printing platform 430 x 430 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 386 x 389 x 458 mm (P1P). Bambu prints P1P and P1S dimensions in the same cell - the P1S is 389 x 389 x 458 mm[1] | 658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[2] |
| Net weight (kg) | 9.65 kg net, 14.30 kg gross[1] | 18.1 kg net, 21.8 kg gross[2] |
| Frame construction & material | Open frame; Bambu offers printable mod-plates for the side panels[1] | CNC-machined aluminium extrusion frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame. An official P1P Enclosure Kit exists as a spare part, and the enclosed version of the same platform is sold as the P1S[1][6] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY driven by two stepper motors, each with its own belt to the printhead. Bambu's wiki states the P1P and P1S share the same motion system[7] | Cartesian i3 bed-slinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three leadscrews driven from a single stepper motor through a belt; the whole bed drops in Z. There is no motorised Z-tilt - bed tramming is by three manual knobs under the bed[7] | Two lead screws with two tie rods[8] |
| Belts (type, width, e.g. Gates?) | Adjustable belt tensioners at the rear; a Belt Tension Monitor reports when tension drifts out of range[7] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)"; no driver part number published[8] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 500 mm/s max toolhead speed (manufacturer claim)[2] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[8] |
| Max acceleration (claimed, mm/s²) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive; Bambu sells a "Stainless Steel Extruder Unit (P1 series)" as the service part[7] | Dual-gear direct extruder with 2 fans[8] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal all-in-one hotend: the nozzle is integrated into the heatblock and joined to the heatsink by a thin metal tube, so the hotend is replaced as a unit. 0.4 mm stainless-steel nozzle included; 0.2/0.6/0.8 mm optional[1][7] | Brass nozzle, 0.4 mm, with a titanium-alloy heat break[8] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 300 C claimed max nozzle temperature[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max build-plate temperature[1] | 85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1] | PEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[8] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Nozzle-touch probing against three ceramic force (piezo) sensors under the heatbed: Z homing works by detecting the force of the nozzle contacting the heatbed. Three manual levelling knobs are also fitted[9][7] | Manual levelling combined with 121-point auto-levelling[8] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - filament run-out sensor[1] | Filament detection and power-loss resume printing[2] |
| Multi-material/multi-color capability or official upgrade path | Compatible with AMS and the AMS hub, up to 16 colours with four AMS units[7] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan fitted; the control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan that the P1S has under closed-loop control are all listed as Optional on the P1P[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | "Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[8] |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-120 V / 220-240 V, 50/60 Hz[2][8] |
| Total rated power draw | Not documented | 320 W rated power, 24 V output[8] |
| 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] | Klipper[8] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 2.7-inch 192x64 monochrome screen, not a touchscreen - control is by button, app or PC application[7] | 4.3-inch colour capacitive touch screen[8] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Button-driven on-device UI on a 192x64 monochrome panel; most interaction is expected to happen in Bambu Studio or Bambu Handy[7] | Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[8] |
| 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[7] | Wi-Fi, USB and WLAN file transfer[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Low-rate chamber monitoring camera, 1280x720 at 0.5 fps, timelapse supported - the 0.5 fps figure is Bambu's own and is far below video rate[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA, PET. Capable: PA, PC, ABS, ASA - the open frame is the limiting factor, and the same table upgrades ABS/ASA to Ideal for the enclosed P1S[1] | PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[8] |
| 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.
