The Saturn 4 Ultra is a large-format resin 3D printer built around a 12K mono LCD with 11520x5120 resolution and 19x24μm XY pixels, so fine detail and smooth surfaces come out sharp across a big build area. Its headline feature is the tilting resin tank, which peels each layer away at an angle and pushes print speeds toward 150 mm/h, well above the slow lift-and-retract motion of older Saturn models. A built-in AI camera watches for an empty plate or warped models, and WiFi transfer plus one-click calibration make it easier to run than most resin printers at this size. It suits hobbyists and small shops printing miniatures, prototypes and dental or jewelry parts who want speed and detail without a workshop-sized machine.

Owners of the Saturn line praise the detail and the faster tilt-release printing, and the Ultra's camera and WiFi are seen as genuine conveniences. Complaints center on resin mess, machine weight and the learning curve for new resin users.
The Elegoo Saturn 4 Ultra is a resin 3D printer that uses stereolithography. It has a 12K mono LCD with a resolution of 11520x5120 and an XY resolution of 19x24 μm. The screen is protected by 9H hardness tempered glass.
Tilt Release tilts the resin tank to separate cured models, with print speeds up to 150 mm/h. A built-in mechanical sensor and spring allow one-click calibration, so it can print right out of the box. A built-in AI camera detects an empty build plate and model warping for real-time monitoring.
Files transfer over WiFi at 6-10 Mbps on 2.4G and 5G networks. Multiple printers on the same LAN can print at the same time. The printer has one-touch build plate locking, a replaceable resin tank lock screw, dual pour spouts and a laser-engraved build plate.
