The ELEGOO Saturn 4 Ultra 12K is a resin 3D printer that combines generous print volume , stunning 12K detail , and intelligent features to boost your productivity. Equipped with a 10-inch 12K monochrome LCD screen with a 19 × 24 μm XY resolution, it ensures smooth surfaces, intricate details, and models that are extremely faithful to the original design.
COB light source technology combined with a Fresnel lens ensures 92% uniformity and an ultra-low astigmatism coefficient of 0.5%, allowing for 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 the same time. The printer also features an integrated AI camera that monitors each step of the process in real time, detecting flaws and even allowing timelapse recordings.
In addition, the Saturn 4 Ultra is equipped with automatic leveling , intelligent self-checking , print resumption after power failure , and a mechanical safety sensor to prevent damage to the LCD, detect residue, and warn of low resin levels.
