| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Mars 5 Ultra. Elegoo's product handle is mars-5-ultra-9k-7inch-monochrome-lcd-resin-3d-printer[1][2][3] | ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[4] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[5] |
| Street price (USD; dated snapshot per entry) | $269.00 in Elegoo's live US product feed, in stock, checked Aug 2026. The Mars 5 Series collection page rendered $259.00 against a $338.00 compare-at price on the same day, so the two Elegoo surfaces disagree by $10[3][2] | $219.00 on us.elegoo.com, Aug 2026, against a compare-at price of $249.00; both the Ribbon-Cable and Type-C printhead variants are the same price[5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Not a trim of the Mars 5 — a different imaging stack and a different release mechanism: 7-inch 9K LCD and 18 um pixels vs 6.6-inch 4K and 35 um, 150 vs 70 mm/h, tilt-release vs straight lift, an AI camera, and Wi-Fi added. Seven bundle SKUs pair it with Mercury Plus V2.0/V3.0 or Mercury XS at $363-$432[6][1][2][3] | Two printhead variants of the same machine are sold under one SKU - "Ribbon-Cable Version" and "Type-C Version" - which use different printhead parts. Within the Neptune 4 family the numbers diverge sharply and get mixed up constantly: Neptune 4 is 225 x 225 x 265 mm with a 110 C bed and 20000 mm/s2; the Plus is 320 x 320 x 385 mm with a 100 C bed and 12000 mm/s2; the Max is 420 x 420 x 480 mm with an 85 C bed and only 8000 mm/s2. The Neptune 4 Pro is a separate model again[5][4][7][8] |
| Market position: superseded? successor announced? | Not documented | Still listed in ELEGOO's US store Neptune section in Aug 2026 alongside the 4 Pro, 4 Plus and 4 Max, but ELEGOO's current development is on the Centauri line[9] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 153.36 x 77.76 x 165 mm[1] | 225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 260 x 268 x 451.5 mm[1] | 475 x 445 x 515 mm. ELEGOO separately publishes a "maximum size for machine activity" of 475 x 550 x 735 mm including rack and tray - the depth to allow for is 550 mm, not 445 mm[4] |
| Net weight (kg) | Approximately 8.8 kg[1] | 8.3 kg net, 10.6 kg gross[4] |
| Frame construction & material | Not documented | CNC-machined aluminium extrusion frame[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a removable UV-blocking cover[1] | Open frame, no enclosure[4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | MSLA with tilt-release: the resin tank tilts after each layer to peel the part rather than pulling straight up. Single Z axis[1] | Cartesian i3 bed-slinger[4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[10] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)" is all ELEGOO publishes; no driver part number is given[10] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[4][7] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[10] |
| Max acceleration (claimed, mm/s²) | Not documented | 20000 mm/s2 max toolhead acceleration (manufacturer claim) - notably higher than the Plus at 12000 and the Max at 8000, because the moving mass is smaller[4][7][8] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Dual-gear direct extruder with 2 fans[10] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[10] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 300 C claimed max nozzle temperature[4] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 110 C max heated bed temperature[4] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[10] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, one click, via an intelligent mechanical sensor. One-Click Self-Check routine. Alarms for resin shortage, residue detection and levelling failure[1] | Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[10] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament detection fitted; power-loss resume printing supported[4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[10] |
| Input voltage (110/220 V, switch or auto) | 100-240 V, 50/60 Hz, 24 V 3 A[1] | 115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[4][10] |
| Total rated power draw | Not documented | 310 W rated power, 24 V output[10] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by Elegoo. Supported slicer is CHITUBOX[1] | Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[10][11] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1] | 4.3-inch colour capacitive touch screen[10] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Not documented | Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[10] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | LAN and USB file transfer; no Wi-Fi is listed for the base Neptune 4, unlike the Plus (USB/LAN/Wi-Fi) and Max (Wi-Fi/USB/WLAN)[4][7][8] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera fitted; Elegoo does not publish its resolution for this model[1] | Not documented |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | AI camera detects empty build plates and print errors[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin. No compatibility list published on this listing[1] | PLA, TPU, PETG, ABS, ASA, Nylon[4] |
| Safety | ||
| Firmware safety limits (max temp cutoffs — exact values) | Overheating protection activates above 80 °C[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Operating sound published as 60 dB or less - a manufacturer figure with no distance or method stated, so it is not comparable with an independently measured reading[10] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 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[12] |
| Resin & MSLA | ||
| Masking LCD | 7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[1][3] | Not documented |
| Light source | 25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[1] | Not documented |
| Light uniformity & intensity | 92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[1] | Not documented |
| Vertical print speedmm/h | 150 mm/h maximum, which Elegoo attributes to the tilt-release mechanism (manufacturer claim). Elegoo also offers switchable slow and fast print modes but does not state the layer height the figure assumes[1] | Not documented |
| Layer exposure times | 1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[1] | Not documented |
| LCD life & replaceability | Masking LCD protected by a scratch-resistant tempered 9H glass cover that also guards against resin leakage. Elegoo publishes no rated screen life in hours and does not state whether the user can replace the LCD[1] | Not documented |
| Resin vat & feeding | Resin tank supplied with the machine; resin-shortage and residue-detection alarms fitted. Capacity not published; no auto-refill[1] | 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.
