| Property | ELEGOO Neptune 3 ProBEDSLINGER | LulzBot TAZ ProBEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | LulzBot |
| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 3 Pro[1] | LulzBot TAZ Pro (LulzBot's own store lists it under Legacy LulzBot printers)[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] | $4,950.00 on buy.lulzbot.com, in stock, 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] | Several TAZ Pro derivatives exist and their specs differ substantially: TAZ Pro S, TAZ Pro XT+, and TAZ Pro Long Bed (282 x 582 x 285 mm, 1.2 mm GammaMaster steel nozzle, 80 °C bed cap, 150 mm/s travel, BLTouch 32-point mesh). The base TAZ Pro is 285 mm cubed with a 0.5 mm hardened-steel nozzle, a 110 °C bed and 300 mm/s travel — do not mix the two spec sets[2][7] |
| Market position: superseded?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 | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[6] | Not documented |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 usable | 225 x 225 x 280 mm; printing platform 235 x 235 mm[1] | 285 x 285 x 285 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] | Not documented |
| Net weight (kg) | 8.1 kg net, 10.15 kg gross[1] | Not documented |
| Frame construction & material | CNC-machined aluminium extrusion frame (Neptune family)[5] | Open frame; movement on GT2 belts with Igus SST rods and polymer bushings[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 i3 bed-slinger[1] | Cartesian bedslinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws[1] | Not documented |
| Belts (type, width, e.g. Gates?) | Not documented | GT2 belt drive[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[1] | Trinamic TMC2130[2] |
| 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] | Not documented |
| Recommended/typical print speed | 60 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max travel speed | Not documented | 300 mm/s maximum travel speed (manufacturer figure)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[1] | Pro Dual Extruder tool head — two active-lifting hot ends for true dual-material printing[2] |
| Filament diameter | Not documented | 2.85 mm standard, 1.75 mm optional[2] |
| 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] | 290 °C maximum hot end temperature[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.5 mm hardened steel[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Hardened steel[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heated bed temperature at 25 C ambient[1] | 110 °C maximum bed temperature[2] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 360 W, 24 V silicone bed heater[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet[1] | Dual-sided borosilicate glass with PEI film[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][8] | Automatic 4-point mesh levelling using a 5 V contact circuit, plus automatic X-axis tramming, Z-offset and backlash compensation[2] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 4-point mesh[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor and power-loss recovery[1] | Filament sensor with both runout and stripping detection[2] |

| Total rated power draw | 300 W rated power, 24 V output[1] | Not documented |
| 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][8] | Marlin[2] |
| Connectivity, UI & Camera | ||

| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | TF (microSD) card and USB cable only - no LAN and no Wi-Fi[1] | USB serial; a 16 GB flash drive is included for standalone printing[2] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][5] | PLA, TPU, ABS, PETG, PVA, PVB, nylon, PC and other materials below 290 °C[2] |
| Safety | ||
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | FCC, CE, RCM, ETL, CSA, OSHWA and WEEE. The OSHWA listing is the open-hardware certification[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[9] | 1 year standard, with extended options. Made in the USA[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification, not an independent measurement)[2] |
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.
