Saturn 4 Ultra 3D Printer (30-150 mm/h & 12K)

The ELEGOO Saturn 4 Ultra 12K is a resin 3D printer that combines a generous print volume , stunning 12K detail , and intelligent features to elevate your productivity. Equipped with a 10-inch 12K mono LCD screen and 19×24μm XY resolution, it ensures smooth surfaces, intricate details, and models that are extremely faithful to the original design.

The COB light source technology combined with a Fresnel lens ensures 92% uniformity and an ultra-low astigmatism coefficient of 0.5%, enabling consistent, high-quality prints. Its tilt release system enables speeds of up to 150 mm/h , reducing production time without compromising accuracy.

With a print volume of 218.88 × 122.88 × 220 mm , you can create larger models or multiple parts at once. The printer also features an integrated AI camera that monitors each step of the process in real time, detecting flaws and even allowing time-lapse recording.

Additionally, the Saturn 4 Ultra is equipped with auto-leveling , smart self-check , power outage resumption , and a mechanical safety sensor to prevent LCD damage, detect residue, and warn of resin shortage.
