Detailed Description

Top-tier 12K LCD Display for Maximum Detail

The Saturn 4 Ultra is equipped with a 10" monochrome 12K LCD display with a resolution of 11520 × 5120 px. This achieves an XY resolution of 19 × 24 µm, which translates into smooth surfaces, sharp edges, and perfectly rendered fine details. It is ideal for figures, hobby models, jewelry, prototypes, and technical parts.

Large Build Volume

The print area of 218.88 × 122.88 × 220 mm provides plenty of space for both larger objects and serial printing of smaller models in one batch. This gives you higher productivity and more efficient use of time and material.

Tilt Release – High Speed Without Compromises

Unique Tilt Release technology tilts the resin vat after every layer. This makes the model peel off the film more easily, reduces the load on the print, and allows the printer to reach up to 150 mm/h in fast mode. For demanding details or specific materials, a slower, more conservative mode can also be selected.

Uniform COB + Fresnel Lighting

The Saturn 4 Ultra utilizes a COB light source combined with a Fresnel collimating lens. The result is an almost parallel light beam with a wavelength of 405 nm and very low angle deviation, ensuring high exposure uniformity across the entire surface. This minimizes dimensional deviations and improves the final print quality.

AI Camera for Print Monitoring

The integrated AI camera monitors the printing process and can recognize potential problems such as model detachment, empty prints, or other anomalies. It also allows for remote print monitoring, so you have your projects under control even without being directly at the printer.

Automatic Leveling and User-Friendliness

Thanks to automatic leveling, there is no need for complex build plate adjustments. The printer comes from the factory practically ready to print – after basic setup, pouring resin, and preparing the file, you can start printing very quickly.

The 4" color capacitive touchscreen offers a clear menu, bright icons, and simple control in just a few steps, which will be appreciated by both beginners and advanced users.

Stable Construction and Quality Mechanics

The robust printer body with a high-quality Z-axis guide (accuracy 0.02 mm) ensures stable movement and eliminates vibrations even at higher speeds. The result is clean layers without significant "banding" and repeatable results even during long prints.

Smart Software and Connectivity

Saturn 4 Ultra supports the CHITUBOX slicer and other commonly used formats such as STL and OBJ. Features include a USB port for offline printing from a flash drive and Wi-Fi connectivity for convenient file transfer from a computer or managing multiple printers on a network.

Suitable Use

ELEGOO Saturn 4 Ultra is suitable for:

• Hobby modelers and figure makers – detailed miniatures, dioramas, collectible models
• Jewelers and designers – fine jewelry, design prototypes
• Technical prototyping – precise parts, housings, small mechanical components
• Dental and laboratory models (depending on the resin used)
• Small series and custom production – thanks to high printing speed and large area

Thanks to the combination of advanced features and intuitive controls, it is suitable for ambitious beginners as well as advanced users and small businesses.
