Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 3 Pro[1]Snapmaker U1 3D Printer[2]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$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[3][4]$849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)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[1][5][6]An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[2]
Market position: superseded? successor announced?Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[6]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable225 x 225 x 280 mm; printing platform 235 x 235 mm[1]270 x 270 x 270 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)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[1][5]584 x 499 x 730 mm[2]
Net weight (kg)8.1 kg net, 10.15 kg gross[1]18.2 kg[2]
Frame construction & materialCNC-machined aluminium extrusion frame (Neptune family)[5]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open as sold; a top cover is an optional accessory that raises the supported material range[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)"; no driver part number published[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)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[1]500 mm/s maximum toolhead speed (manufacturer claim)[2]
Recommended/typical print speed60 mm/s recommended printing speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)Not documented20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented32 mm3/s maximum hotend flow (manufacturer claim)[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaping with an accelerometer, run as a calibration routine[2]
Extrusion Pressure Control
Pressure advance (Klipper) / linear advance (Marlin) supported?Not documentedPressure advance, with automatic flow compensation calibration[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, titanium-alloy heat break[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[1][5]300 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedStainless steel as standard; hardened steel needed for fibre-filled grades[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient[1]100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet[1]Flexible steel sheet with a PEI surface[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)36-point auto-levelling (the Neptune 4 family moved to 121 points)[1][7]Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor and power-loss recovery[1]Filament run-out detection, plus air-printing detection and RFID filament recognition[2]
Multi-material/multi-color capability or official upgrade pathNot documentedFour toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedMain plus auxiliary part-cooling fans[2]
Electronics & Power
Total rated power draw300 W rated power, 24 V output[1]Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Marlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[1][7]Klipper[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]3.5-inch, 320 x 480 touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveTF (microSD) card and USB cable only - no LAN and no Wi-Fi[1]Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documented2 MP built-in chamber camera for live view[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery supported; mechanism not published[2]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][5]Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Operating sound published as 48 dB or less - a manufacturer figure with no distance or method stated[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)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[8]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.
