Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Mars 5. Elegoo's own product handle spells the configuration out: mars-5-4k-6-6inch-monochrome-lcd-resin-3d-printer[1][2][3]ELEGOO Neptune 4 Plus[4]
Release date (announcement and actual shipping)Not documentedListed on the ELEGOO US store from 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[5][6]
Street price (USD; dated snapshot per entry)$179.00 on us.elegoo.com against a $225.00 compare-at price (20% off), in stock, checked Aug 2026. The live product feed shows the same $179.00[2][3]$309.00 on us.elegoo.com, Aug 2026, against a compare-at price of $425.00. Only a Ribbon-Cable printhead variant is listed for the Plus, unlike the Neptune 4 and 4 Max which also offer a Type-C version[5][7][6]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Sold beside the Mars 5 Ultra, which is a materially different machine: 7-inch 9K masking LCD vs 6.6-inch 4K, 18 um vs 35 um pixels, 150 vs 70 mm/h, a 4.0-inch capacitive control screen vs 3.5-inch resistive, and Wi-Fi (the plain Mars 5 is USB only). Elegoo lists ten further Mars 5 / Mars 5 Ultra bundle SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[1][8][2][3]Middle model of the Neptune 4 family. Against the base Neptune 4: bigger (320 x 320 x 385 mm), but a lower bed ceiling (100 C rather than 110 C) and much lower acceleration (12000 rather than 20000 mm/s2). Against the Max: smaller and lighter (14.4 kg against 18.1 kg) but with a higher bed ceiling (100 C against 85 C) and higher acceleration (12000 against 8000). Its Z drive is 2 lead screws with 2 tie rods, where the Centauri machines use 3 lead screws[4][9][10][11]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable143.43 x 89.6 x 150 mm[1]320 x 320 x 385 mm; printing platform 330 x 330 mm[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)230 x 230 x 433.5 mm[1]533 x 517 x 638 mm; ELEGOO also publishes a maximum size for machine activity of 578 x 750 x 860 mm including rack and tray, so allow 750 mm of depth[4]
Net weight (kg)Approximately 6.6 kg[1]14.4 kg net, 16.65 kg gross[4]
Frame construction & materialMetal frame with adjustable foot pads[1]CNC-machined aluminium extrusion frame (Neptune 4 family)[9]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Open frame, no enclosure[4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)MSLA — UV LCD masked stereolithography. Single Z axis, build plate lifting straight out of the vat (no tilt-release on this model, unlike the Mars 5 Ultra)[1][8]Cartesian i3 bed-slinger[4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedTwo lead screws with two tie rods[4]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)" is all ELEGOO publishes; the driver part number is not given on the product page[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented30-500 mm/s printing speed, with 250 mm/s given by ELEGOO as the recommended figure - the 500 mm/s number is a ceiling, not a working speed[4]
Recommended/typical print speedNot documented250 mm/s recommended printing speed (manufacturer figure)[4]
Max acceleration (claimed, mm/s²)Not documented12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedDual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[4][11]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle, 0.4 mm, with a titanium-alloy heat break[4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented300 C claimed max nozzle temperature[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented100 C max heated bed temperature at 25 C ambient[4]
Bed surface (material, texture, coating), single/double-sidedLaser-engraved build plate with a quick-release design[1]PEI spring steel sheet; ELEGOO notes it is now upgraded to a dual-sided textured PEI + PLA-specific surface[4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic levelling, one click. An intelligent mechanical sensor detects resin residue to prevent LCD damage[1]Manual levelling combined with 121-point auto-levelling[4]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out sensor and power-loss recovery; no camera, no clog detection, no auto filament unloading[4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU is published[4]
Input voltage (110/220 V, switch or auto)100-240 V, 50/60 Hz, 24 V 3 A[1]Not documented
Total rated power drawNot documented320 W rated power; 24 V output; 110-120 V / 220-240 V input[4]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named by Elegoo. Supported slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[1]Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 Plus, rather than the ELEGOO OS branding used on the Centauri machines)[4][11]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[1]4.3-inch colour capacitive touch screen[4]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedColour capacitive touch UI; ElegooSlicer is recommended, with Orca and Cura also supported[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB only — no Wi-Fi on this model[1]USB, LAN and Wi-Fi[4]
Materials Support
Officially supported filament list405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1]PLA, TPU, PETG, ABS, ASA, Nylon[4]
Safety
Firmware safety limits (max temp cutoffs — exact values)Intelligent overheating protection stops printing above 80 °C[1]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating sound is published as 65 dB or less - a manufacturer figure with no measuring distance or method given, so it is not comparable with a reviewer's dB reading[4]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented12 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 LCD6.6-inch 4K monochrome masking LCD, 4098 x 2560 px, XY pixel pitch 35 x 35 um (manufacturer specification)[1][3]Not documented
Light sourceCOB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[1]Not documented
Vertical print speedmm/h70 mm/h maximum (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[1]Not documented
Release filmPFA film with a non-stick surface. No rated life published[1]Not documented
Resin vat & feedingReplaceable resin tank with two pouring openings and screw caps. An intelligent mechanical sensor detects resin residue in the vat. Capacity not published; no auto-refill[1]Not documented
Fume extractionNone fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[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.
