ELEGOO Jupiter 2

# ELEGOO Jupiter 2

Overview

The ELEGOO Jupiter 2 is a large-format MSLA resin 3D printer for large models, prototypes, studio work, and batch production. It combines a 302 × 162 × 300 mm build volume with a 14-inch 16K monochrome LCD at 15120 × 6230 pixels, producing a 20 × 26 µm XY pixel size.

The platform adds several features that are especially useful on long resin jobs: automatic multi-point leveling, 30°C smart tank heating, automatic resin feeding and recycling, residue and resin-shortage detection, built-in camera monitoring, power-loss recovery, dual-band Wi-Fi, and 8 GB internal storage.

ELEGOO specifies 0.01–0.20 mm layer thickness and printing speeds up to 90 mm/h. Because Jupiter 2 is an MSLA printer, its published speed is a vertical build rate in millimeters per hour rather than the millimeters-per-second convention commonly used for FDM printers.

For current product information, see the official ELEGOO Jupiter 2 page and the official Jupiter 2 FAQ.

Technical Specifications

Large-Format 16K Printing

The 302 × 162 × 300 mm workspace is the main reason to choose Jupiter 2 over smaller resin printers.

It can accommodate large single-piece models, tall parts, props, architectural components, prototypes, and dense batches of smaller parts. ELEGOO describes its build volume as approximately 2.5 times larger than Saturn 4.

The 14-inch 16K display maintains fine planar detail across that larger print area instead of trading resolution for capacity.

For a smaller platform with finer XY pixel dimensions, compare the ELEGOO Saturn 4 Ultra 16K. The ELEGOO Mars 5 Ultra is a more compact alternative when desktop footprint matters more than build volume.

20 × 26 µm XY Pixel Size

Jupiter 2 uses a 15120 × 6230 exposure panel with a rectangular 20 × 26 µm pixel pitch.

The two XY axes, therefore, do not have identical pixel dimensions.

Pixel size is useful for comparing the imaging system, but it is not a guaranteed finished-part tolerance. Resin shrinkage, exposure, support placement, orientation, calibration, and post-curing can all affect dimensions.

Layer Thickness and Print Speed

ELEGOO specifies:

• Layer thickness: 0.01–0.20 mm
• Maximum print speed: 90 mm/h

Actual print time depends on resin, exposure, lift settings, layer height, part cross-section, temperature, and support strategy.

A large-format resin print can still take many hours, even when the printer has a high-rated vertical build speed.

30°C Smart Resin Heating

The resin tank integrates temperature sensing and automatic heating to maintain resin at about 30°C.

Warmer resin generally flows more easily, which can improve consistency in cooler rooms or with more viscous formulations.

Automatic Resin Feeding and Recycling

The resin-management system uses a two-way pump for automatic feeding and recycling.

It can:

• Refill the tank as resin level drops
• Alert the user when resin is low
• Recycle excess resin
• Reduce the risk of long prints stopping because the vat runs dry

ELEGOO designed the integrated bottle system around its 2 kg resin bottle format.

The printer itself supports most standard 405 nm photopolymer resins, according to ELEGOO's Jupiter 2 FAQ. Basic resin compatibility and physical compatibility with the automatic bottle system are separate considerations.

When changing resin color or chemistry, the tank and feed system should be cleaned so the next material is not contaminated.

Resin Compatibility

ELEGOO states that most standard 405 nm resins are compatible and recommends a small test print when using a new resin.

Common categories include:

• Standard resin
• ABS-like resin
• Water-washable resin
• Tough resin
• Engineering resin
• Castable resin
• Plant-based resin

Water-washable clear resin is specifically confirmed as compatible in ELEGOO's Jupiter 2 FAQ.

For indexed examples, compare ELEGOO ABS-Like Resin 3.0 Pro and Siraya Tech Fast ABS-Like Resin.

Exposure and supports should be tuned for the exact resin rather than copied from another formulation.

Automatic Leveling

Jupiter 2 uses four independent force sensors for multi-point automatic leveling.

This reduces routine build-plate calibration and helps establish a consistent first layer across the large print area.

ELEGOO also provides real-time sensor feedback for manual calibration when manual adjustment is required.

Automatic leveling reduces setup work, but first-layer success still depends on build-plate condition, release film, resin settings, and cleanliness.

Mechanical Sensing and Protection

The printer monitors several failure conditions that matter on a large resin machine.

ELEGOO lists:

• Resin-shortage detection
• Residue detection
• Leveling-failure detection
• Resin-bottle monitoring
• Resin-temperature detection
• LED-temperature monitoring
• Power-loss recovery

If LED temperature exceeds 80°C, the printer can pause and alert the user.

Residue detection is particularly useful because cured debris trapped between the build plate and release film can damage a large LCD on the next print.

Camera and Network Workflow

The built-in chamber camera and LED support:

• Real-time monitoring
• Timelapse capture
• Remote control through ELEGOO Matrix

Jupiter 2 includes dual-band Wi-Fi and supports Wi-Fi cluster management, which is useful for studios operating multiple printers.

Its 8 GB internal storage supports local job handling, while USB remains available for file transfer.

Current Slicer Compatibility

A significant workflow limitation is current slicer support.

ELEGOO's Jupiter 2 FAQ states that the printer currently supports ELEGOO SatelLite. Support for additional slicers such as Lychee and Chitubox Pro is planned, but should not be treated as available until ELEGOO releases it.

The current FAQ also states that Jupiter 2 does not support the `.ctb` file format.

This is important for users migrating from older resin-printer workflows centered on Chitubox or Lychee.

Quick-Lock PFA Release Film

Jupiter 2 uses a tool-free quick-lock PFA release-film system.

ELEGOO's current replacement film is:

• 381 × 255 mm
• 0.15 mm thick
• Rated at 92% UV transmittance

The release film is a consumable and should be checked regularly for damage, dents, scratches, or clouding.

Build Plate and Large-Part Removal

The printer uses a laser-engraved, dual-grip quick-release build plate.

For full-size prints, ELEGOO notes that the resin tank must be removed before the model can be taken out.

That is a practical consequence of the large build area and enclosure geometry and is worth accounting for when planning maximum-size parts.

A resin drip tray is included to help keep the workspace cleaner during plate removal.

Ventilation and Air-Purifier Options

Jupiter 2 is compatible with the optional ELEGOO MarsMate Air Purifier.

It also has a 75 mm rear exhaust port for connecting an external ventilation system.

The purifier is not included with the base printer.

Resin printing should still use suitable ventilation, gloves, eye protection, and safe cleanup procedures. Filtration reduces exposure but does not replace correct resin handling.

Jupiter 2 vs Saturn 4 Ultra 16K

The ELEGOO Saturn 4 Ultra 16K is a smaller, faster-rated alternative.

Jupiter 2 offers:

• Larger 302 × 162 × 300 mm build volume
• Automatic resin feed and recycling
• 30°C heated resin tank
• Four-sensor automatic leveling

Saturn 4 Ultra 16K prioritizes a smaller footprint, finer XY pixel size, and higher rated vertical speed.

Jupiter 2 vs Formlabs Form 4

The Formlabs Form 4 targets a more tightly integrated professional resin workflow.

Form 4 emphasizes validated materials, controlled post-processing, fleet tools, and a managed production ecosystem.

Jupiter 2 offers a much larger build volume at a lower hardware price and supports most standard 405 nm resins.

The best choice depends on whether the priority is large-format flexibility or a tightly validated resin-production ecosystem.

Jupiter 2 vs Anycubic Photon P1

The Anycubic Photon P1 is another indexed resin platform with a heated-resin workflow.

Jupiter 2 differentiates itself through its 302 × 162 × 300 mm build volume, 14-inch 16K screen, automatic resin feeding/recycling, four-sensor auto leveling, and cluster management.

Comparison With Related Resin Printers

The Jupiter 2 stands out primarily for build volume and automated resin management, while smaller alternatives such as the Saturn 4 Ultra 16K and Mars 5 Ultra prioritize compact size, finer pixel dimensions, or higher rated print speed.

Limitations and Practical Considerations

• Full-size prints require removing the resin tank before model removal.
• The automatic bottle system is designed around ELEGOO's 2 kg bottles.
• Most standard 405 nm resins are compatible, but exposure must be tuned to each formulation.
• Current slicer support centers on ELEGOO SatelLite.
• Lychee and Chitubox Pro support is planned rather than currently confirmed.
• `.ctb` files are not currently supported.
• The 30°C system heats the resin tank, not the chamber.
• The optional MarsMate purifier is not included.
• Automatic resin management does not eliminate cleaning when switching resins.
• Resin printing still requires ventilation, PPE, washing, and post-curing.
• Maximum 90 mm/h speed depends on the selected resin and profile.
• Physical build-plate dimensions are not separately published from the printable XY area.

Callout Section

Recommended use: Choose ELEGOO Jupiter 2 when large resin capacity, automated resin handling, heated resin management, and remote monitoring matter more than a compact footprint. It is particularly useful for large display models, prototypes, batch production, and studio workflows that would otherwise require splitting jobs across smaller printers.
