| Class | BEDSLINGER | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 3 Pro[1] | UltiMaker S8 3D Printer[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[4] | Launched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[3] |
| 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[4][5] | Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[2][3] |
| 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][6][7] | Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[2][3] |
| Market position: superseded? successor announced? | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[7] | Not documented |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] | 330 x 240 x 300 mm[2][3] |
| 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][6] | 495 x 585 x 800.5 mm printer only; 495 x 500 x 1210.5 mm as the Pro Bundle[2][3] |
| Net weight (kg) | 8.1 kg net, 10.15 kg gross[1] | 30 kg printer only; 47.7 kg as the Pro Bundle[2][3] |
| Frame construction & material | CNC-machined aluminium extrusion frame (Neptune family)[6] | Fully assembled, made in Europe[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Enclosed, with an Air Manager UltiMaker says removes up to 95% of ultrafine particles[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Build-volume temperature under 50 °C with open-loop control (manufacturer figure)[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[2][3] |
| 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] | Up to 500 mm/s in XY (manufacturer claim)[2][3] |
| Recommended/typical print speed | 60 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | Not documented | Up to 50,000 mm/s2 (manufacturer claim)[2][3] |
| Jerk / square-corner-velocity setting (exact value) | Not documented | Jerk up to 100,000,000 mm/s3 (manufacturer claim)[2][3] |
| Max volumetric flow claimed (mm³/s) | Not documented | Up to 35 mm3/s extrusion flow (manufacturer claim)[2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[1] | Dual gripper feeder with tension adjustment, release function and filament feed-rate control[2][3] |
| Filament diameter | Not documented | 2.85 mm[2][3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle, 0.4 mm, titanium-alloy heat break[1] | Swappable print cores; AA+ 0.40 x2 included, BB 0.40 / CC+ 0.40 / DD 0.40 sold separately[2][3] |
| 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][6] | Up to 340 °C (manufacturer claim)[2][3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heated bed temperature at 25 C ambient[1] | Up to 120 °C on a flexible PEI plate (manufacturer claim)[2][3] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet[1] | Flexible PEI plate[2][3] |
| 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] | Inductive probing, integrated into the print head[2][3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor and power-loss recovery[1] | Not documented |
| Spool holder location & max spool size; drybox compatibility | Not documented | Dual spool holder with NFC recognition on the printer; the Pro Bundle substitutes a 6-spool Material Station with NFC and a dual-geared abrasion-resistant feeder[2][3] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | Air Manager, which UltiMaker says removes up to 95% of ultrafine particles[2][3] |
| Electronics & Power | ||
| 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] | Not published; print preparation is UltiMaker Cura 5.10 or newer, fleet management via UltiMaker Digital Factory[2][3] |
| 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] | Wi-Fi 2.4 and 5 GHz (802.11a/b/g/n/ac), Gigabit Ethernet, USB 2.0[2][3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Full HD HDR camera[2][3] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[1][6] | UltiMaker cites 301+ compatible materials including its own PLA, PETG, ABS, CPE, CPE+, PC, TPU and PET-CF, plus third-party grades[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] | Under 50 dBA operating sound, manufacturer figure. No independent measurement; distance and method not stated[2][3] |
| 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] | 12 months, extendable to 5 years with an UltiMakerCare plan[2][3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Dimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[2][3] |
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.
