| Brand | Bambu Lab | ELEGOO |
| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab A2L[1] | ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[2] |
| Release date (announcement and actual shipping) | Pre-orders opened 1 June 2026 (Tom's Hardware spec box); Tom's Hardware review published 27 June 2026[3] | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[4] |
| Launch MSRP (USD) | $469 standalone, $569 Combo at launch[3] | Not documented |
| Street price (USD; dated snapshot per entry) | From $469.00 on the Bambu Lab US store, Aug 2026[5] | $219.00 on us.elegoo.com, Aug 2026, against a compare-at price of $249.00; both the Ribbon-Cable and Type-C printhead variants are the same price[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Standalone and Combo (with AMS lite) SKUs, and an optional cutting/drawing module (blade cutter and pen plotter, 300x300 mm cutting area) that is a separate attachment, not a printer variant. Do not carry A1 or A1 mini figures across: the A2L is a different, much larger machine at 12.8 kg[1][3] | Two printhead variants of the same machine are sold under one SKU - "Ribbon-Cable Version" and "Type-C Version" - which use different printhead parts. Within the Neptune 4 family the numbers diverge sharply and get mixed up constantly: Neptune 4 is 225 x 225 x 265 mm with a 110 C bed and 20000 mm/s2; the Plus is 320 x 320 x 385 mm with a 100 C bed and 12000 mm/s2; the Max is 420 x 420 x 480 mm with an 85 C bed and only 8000 mm/s2. The Neptune 4 Pro is a separate model again[4][2][6][7] |
| Market position: superseded? successor announced? | Not documented | Still listed in ELEGOO's US store Neptune section in Aug 2026 alongside the 4 Pro, 4 Plus and 4 Max, but ELEGOO's current development is on the Centauri line[8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 320 x 325 mm (manufacturer figure)[1] | 225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 544 x 529 x 505 mm[1] | 475 x 445 x 515 mm. ELEGOO separately publishes a "maximum size for machine activity" of 475 x 550 x 735 mm including rack and tray - the depth to allow for is 550 mm, not 445 mm[2] |
| Net weight (kg) | 12.8 kg net[1] | 8.3 kg net, 10.6 kg gross[2] |
| Frame construction & material | Aluminium and steel chassis with a plastic outer frame; Tom's Hardware describes a triangular gantry frame the base drops into[1] | CNC-machined aluminium extrusion frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian bed-slinger - Tom's Hardware's assembly description has the heatbed bolting to a Y-carriage inside the gantry frame[3] | Cartesian i3 bed-slinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not published in the spec sheet; no teardown source found that documents the Z drive[1] | Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[9] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)" is all ELEGOO publishes; no driver part number is given[9] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim)[1] | 500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[2][6] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[9] |
| Max acceleration (claimed, mm/s²) | 10 m/s2 = 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20000 mm/s2 max toolhead acceleration (manufacturer claim) - notably higher than the Plus at 12000 and the Max at 8000, because the moving mass is smaller[2][6][7] |
| Max volumetric flow claimed (mm³/s) | 28 mm3/s claimed, measured by Bambu on a 150 mm round single-wall model in Bambu PLA Basic at 220 C - note this test uses PLA, unlike the ABS-based figures Bambu quotes for its enclosed machines, so it is not directly comparable[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with a servo extruder motor and hardened-steel extruder gears; built-in filament cutter[1] | Dual-gear direct extruder with 2 fans[9] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Stainless-steel nozzle; 0.2/0.4/0.6/0.8 mm supported. Bambu's A2L sheet does not state whether the hotend is all-metal[1] | Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[9] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 300 C claimed max nozzle temperature[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 80 C max heatbed temperature[1] | 110 C max heated bed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate included; Engineering Plate and Cool Plate SuperTack also supported[1] | PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[9] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling with automatic Z: Tom's Hardware confirms the nozzle is used as the probe and the machine can re-check level before each print[3] | Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[9] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, filament odometry, tangle sensor and clumping detection[1] | Filament detection fitted; power-loss resume printing supported[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan and hotend cooling fan, both closed-loop controlled. No auxiliary part-cooling fan and no chamber fan[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[9] |
| Input voltage (110/220 V, switch or auto) | Not documented | 115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[2][9] |
| Total rated power draw | Not documented | 310 W rated power, 24 V output[9] |
| 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 (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[9][11] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 240x320 touchscreen[1] | 4.3-inch colour capacitive touch screen[9] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus mobile app and PC app[1] | Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[9] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | 2.4 GHz Wi-Fi only (802.11 b/g/n), Bambu-Bus, microSD card. Ethernet not available[1] | LAN and USB file transfer; no Wi-Fi is listed for the base Neptune 4, unlike the Plus (USB/LAN/Wi-Fi) and Max (Wi-Fi/USB/WLAN)[2][6][7] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in low-frame-rate camera, up to 1080p, timelapse supported[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Suitable: PLA, PETG, TPU, PVA. PLA-CF and PETG-CF suitable only after fitting a hardened-steel nozzle. ABS, ASA, PA, PC and PET are listed as not recommended on the compare page[1][12] | PLA, TPU, PETG, ABS, ASA, Nylon[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Operating sound published as 60 dB or less - a manufacturer figure with no distance or method stated, so it is not comparable with an independently measured reading[9] |
| 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] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (27 June 2026)[3] | 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.
