The Elegoo Saturn 4 Ultra features innovative tilt-release technology. By tilting the resin tank, the model peels away quickly from the release film, enabling high-speed printing of up to 150 mm/h. Switch seamlessly between fast and slow print modes to suit your project needs—flexible, efficient, and fast. Equipped with a 10-inch 12K mono LCD (11520 × 5120 resolution, 19 × 24μm XY resolution), the Saturn 4 Ultra delivers exceptional clarity and precision. Expect exquisite, high-fidelity prints with sharp edges and intricate textures. A 405nm COB light source combined with a Fresnel collimating lens ensures ultra-low astigmatism coefficient (0.5%), 92% field uniformity, and angle deviation control below 5°. These specs result in accurate, even printing with delicate surface finishes and high detail integrity. Enjoy a plug-and-play experience. One-Click Self-Check runs a full diagnostic to verify system readiness before printing begins. One-Click Automatic Levelling uses an intelligent mechanical sensor to level the build plate automatically, eliminating manual adjustments and saving you time. The built-in AI camera offers real-time error detection, monitoring for issues like empty build plate and model warping. Get immediate alerts, reduce print failures, and avoid wasted resin.
