| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 Max[1] | Snapmaker J1S High Speed IDEX 3D Printer[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[4] | Not documented |
| Street price (USD; dated snapshot per entry) | $389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[4] | $1,399.00 at MatterHackers, listed as currently unavailable with a pre-order option quoting roughly 5 weeks, checked Aug 2026[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[1][5][6][4] | The J1s differs from the original J1 by an additional part-cooling fan. Usable volume depends on the print mode: 300 x 200 x 200 mm in default and backup modes, 160 x 200 x 200 in copy mode, 150 x 200 x 200 in mirror mode[2][3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 420 x 420 x 480 mm; printing platform 430 x 430 mm[1] | 300 x 200 x 200 mm in default and backup modes[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[1] | 539 x 401 x 464 mm[2] |
| Net weight (kg) | 18.1 kg net, 21.8 kg gross[1] | 25 kg net[2] |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Aluminium-alloy frame with one-piece die casting and linear rails; Snapmaker quotes rail repeatability of +/-0.03 mm in X/Y and +/-0.02 mm in Z[3] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | IDEX — two independently driven extruders[2][3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails[3] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws with two tie rods[7] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[7] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim)[1] | 350 mm/s maximum (manufacturer claim)[3] |
| Recommended/typical print speed | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[7] | Not documented |
| Max acceleration (claimed, mm/s²) | 8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1] | 10,000 mm/s2 maximum (manufacturer claim)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[7] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle, 0.4 mm, with a titanium-alloy heat break[7] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 300 °C maximum (manufacturer claim)[2][3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[1] | 100 °C maximum (manufacturer claim)[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[7] | Custom dual-sided PEI glass plate: glossy glass on one face, PEI coating on the other[2][3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Manual levelling combined with 121-point auto-levelling[7] | 3-point bed levelling, which Snapmaker contrasts with 9-16 point systems; assisted calibration quoted at about 10 minutes[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection and power-loss resume printing[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[7] | Not documented |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | 1 GB RAM, 8 GB eMMC; the 5-inch display runs Android[2] |
| Input voltage (110/220 V, switch or auto) | 100-120 V / 220-240 V, 50/60 Hz[1][7] | AC 100-240 V, 50/60 Hz, 4.4 A max input; DC 24 V, 400 W max output[2] |
| Total rated power draw | 320 W rated power, 24 V output[7] | 400 W maximum output[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[7] | Not named by Snapmaker; the supplied slicer is Luban, with third-party software supported[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[7] | 5-inch Android display, 1280 x 720[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[7] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB and WLAN file transfer[1] | Wi-Fi, USB cable, USB flash drive[2] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[1] | PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[7] | Less than 50 dBA claimed by the manufacturer. No independent measurement; distance and method not stated[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 |
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.
