| Property | ELEGOO Neptune 3 ProBEDSLINGER | Stratasys F120INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | Stratasys |
| Class | BEDSLINGER | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 3 Pro[1] | Stratasys F120, part of the Stratasys F123 Series[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[3] | The F123 series spec sheet carried is revision 0721a (July 2021). Stratasys does not print a launch date on it[2] |
| 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] | Not documented |
| 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] | The F120 is the odd one out in the series: smaller cabinet (889 x 870 x 721 mm, 124 kg vs 1,626 x 864 x 711 mm, 227 kg), two external material coil boxes rather than internal spool bays, only two model materials, and no 0.127 mm layer option. Same build size as the F170 but not the same machine[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| Market position: superseded?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 | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[6] | Not documented |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 usable | 225 x 225 x 280 mm; printing platform 235 x 235 mm[1] | 254 x 254 x 254 mm (10 x 10 x 10 in)[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] | 889 x 870 x 721 mm (35 x 35 x 29 in)[2] |
| Net weight (kg) | 8.1 kg net, 10.15 kg gross[1] | 124 kg (F120) or 227 kg with consumables (F170, F270, F370)[2] |
| Frame construction & material | CNC-machined aluminium extrusion frame (Neptune family)[5] | Fully enclosed office/classroom-grade cabinet, factory assembled[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Enclosed build chamber[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two 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] | Not documented |
| Recommended/typical print speed | 60 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-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] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heated bed temperature at 25 C ambient[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet[1] | Not documented |
| 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] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor and power-loss recovery[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-132 V / 15 A or 200-240 V / 7 A, 50/60 Hz[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][7] | Proprietary Stratasys firmware; print preparation is GrabCAD Print. The F370 additionally carries an Insight software licence and DoD STIG compliance powered by Red Hat Enterprise Linux[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[1] | Not documented |
| 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-drive | TF (microSD) card and USB cable only - no LAN and no Wi-Fi[1] | Wired TCP/IP at 100 Mbps minimum, 100base-T Ethernet, RJ45. Wireless-ready IEEE 802.11 n/g/b with WPA2-PSK or 802.1x EAP, CCMP/TKIP encryption[2] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][5] | ABS-M30 and ASA, with SR-30 support material. Notably the F120 does NOT get PLA, FDM TPU 92A or ABS-CF10, and cannot use the 0.127 mm layer height[2] |
| Safety | ||
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | CE (low-voltage and EMC directives), FCC, EAC, cTUVus, KC, RoHS, WEEE, REACH, RCM[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] | 46 dB maximum during build, 35 dB idle — manufacturer specification, no distance or method stated, and not an independent measurement[2] |
| 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 |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Parts produced within +/-0.200 mm or +/-0.002 mm/mm, whichever is greater. Manufacturer figure derived from statistical data at 95% dimensional yield; Z accuracy carries an extra -0.000/+slice-height tolerance[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.
