Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab A2L[1]ELEGOO Neptune 3 Pro[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 11 November 2022 (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]$259.99 on us.elegoo.com, Aug 2026, with the compare-at price also $259.99 - notably more than the newer and far faster Neptune 4 at $219[4][6]
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]The last Neptune 3 still listed; the 3 Plus and 3 Max are gone from the store's Neptune section. Do not read Neptune 4 figures onto it: the 3 Pro runs Marlin, not Klipper, tops out at 180 mm/s rather than 500, uses a 36-point mesh rather than 121-point, and its nozzle stops at 260 C rather than 300 C. Its machine size, 475 x 445 x 515 mm, is identical to the Neptune 4's, so body dimensions will not tell them apart[2][7][8]
Market position: superseded? successor announced?Not documentedSuperseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable330 x 320 x 325 mm (manufacturer figure)[1]225 x 225 x 280 mm; printing platform 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 - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[2][7]
Net weight (kg)12.8 kg net[1]8.1 kg net, 10.15 kg gross[2]
Frame construction & materialAluminium 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 (Neptune family)[7]
Enclosure: open / enclosed; panel material; door/lidOpen 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-backlashNot published in the spec sheet; no teardown source found that documents the Z drive[1]Two lead screws[2]
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)[1]30-180 mm/s, with 60 mm/s given by ELEGOO as the recommended speed - a pre-Klipper machine, and the slowest in this file apart from the OrangeStorm Giga[2]
Recommended/typical print speedNot documented60 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)10 m/s2 = 10000 mm/s2 max toolhead acceleration (manufacturer claim)[1]Not documented
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 nameDirect drive with a servo extruder motor and hardened-steel extruder gears; built-in filament cutter[1]Dual-gear direct extruder with 2 fans[2]
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, titanium-alloy heat break[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[2][7]
Heated Bed & Surface
Max bed temp claimed AND firmware limit80 C max heatbed temperature[1]100 C max heated bed temperature at 25 C ambient[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate included; Engineering Plate and Cool Plate SuperTack also supported[1]PEI spring steel sheet[2]
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]36-point auto-levelling (the Neptune 4 family moved to 121 points)[2][9]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, filament odometry, tangle sensor and clumping detection[1]Filament run-out sensor and power-loss recovery[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan and hotend cooling fan, both closed-loop controlled. No auxiliary part-cooling fan and no chamber fan[1]Not documented
Electronics & Power
Total rated power drawNot documented300 W rated power, 24 V output[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]Marlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[2][9]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch 240x320 touchscreen[1]4.3-inch colour capacitive touch screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus mobile app and PC app[1]Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drive2.4 GHz Wi-Fi only (802.11 b/g/n), Bambu-Bus, microSD card. Ethernet not available[1]TF (microSD) card and USB cable only - no LAN and no Wi-Fi[2]
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 listSuitable: 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][11]PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[2][7]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating sound published as 48 dB or less - a manufacturer figure with no distance or method stated[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[12]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[13]
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.
