Tilt Release Technology, Ultra Fast Printing

The Elegoo Saturn 4 UItra adopts tilt release technology, which enables the model to be peeled off from the release film quickly by tilting the resin tank, achieving a fast printing speed up to 150mm/h. You can switch between the fast and slow print modes seamlessly as needed, enjoying a flexible and efficient printing.


Unmatched Details With 12K Mono LCD

With a 10-inch 12K mono LCD, the Saturn 4 Ultra boasts an incredible resolution of 11520x5120 and an XY resolution of 19x24μm, presenting you exquisite models with stunning clarity and precision.


COB & Fresnel Collimating Lens For Smoother Surface

When the COB light source emits light at 405nm with the combination of Fresnel collimating lens, it can achieve an ultra-low astigmatism coefficient of 0.5%, an exceptional field uniformity of 92%, and a precise angle deviation control below 5° on the forming surface, realizing accurate and even printing results with delicate finishing and intricate details.


Self-Check & Automatic Leveling Print Right Out Of The Box

The Saturn 4 Ultra brings hassle-free experience with its smart self-check and automatic leveling function. Simply unbox, power on, and print—making it ultimate printing experience.

One-Click Self-Check
With one single click, the Saturn 4 Ultra will perform a quick self-check to verify whether its components are working properly before your printing starts.

One-Click Automatic Leveling
Thanks to its intelligent mechanical sensor, the build plate will be automatically leveled every time once you click the button, saving your time and efforts.


AI Camera Intelligent Detection, Minimize Potential Loss

Experience failure detection and real-time monitoring of the printing status with the AI camera. The AI camera can effectively detect empty build plate and model warps, enabling you to promptly resolve issues, save your time and effort, and ensure high-quality prints.


Smart Mechanical Sensor, Enjoy Worry-Free Printing

Equipped with a mechanical sensor, the Saturn 4 Ultra supports residue detection to prevent damage to the LCD screen, as well as resin shortage and leveling failure alarm to further enhance the safety and reliability during printing.


Real-Time Monitoring And Time-Lapse Photography

Keep updated on your print progress, ensuring everything is running smoothly. Capture captivating time-lapse videos of your creations and share the excitement with others.


User-Friendly Design

ELEGOO is committed to providing users a convenient printing experience. From the quick-release design of the build plate to the dual pour spouts design of the resin tank, along with the drip tray design to prevent resin drips, the replaceable tank lock, and the flip-up cover design for effortless access, every detail has been carefully considered to make your operation easier and more comfortable.


Easily manage multiple printers simultaneously from one device. Whether you have one or more printers, you can efficiently manage your print projects once at a time.


Powered by self-developed system with 8G RAM, which guarantees stable file transfer and faster computing, the Saturn 4 Ultra offers a smoother and more efficient printing experience.

Experience seamless and user-friendly operation with the 4-inch capacitive touch screen, designed with a vertical layout and an intuitive interface.


PFA release film offers superior release performance, as its non-stick surface prevents the resin from adhering to the film, making it easier to peel off.


The Elegoo Mars Mate air purifier's built-in high-density activated carbon filter can effectively absorb resin odor, with the purification efficiency up to 95% for TVOC.


Designed with a solid metal body, the Saturn 4 Ultra can maintain its precision even after millions of printing layers.
