Elegoo's Saturn 4 Ultra combines excellent 12K precision with superior usability. While the simple yet elegant design blends seamlessly into any environment, the real value of this resin printer lies in its advanced features. By integrating an AI camera for Intelligent Detection, the printer is able to identify potential problems during the printing process, meaning a smoother printing experience for you.

10-inch 12K monochrome LCD screen

The Saturn 4 Ultra features a 10-inch 12K monochrome LCD screen with 11520 x 5120 pixel resolution and 19 x 24 μm XY resolution, delivering impressive detail for high-resolution prints.

Tilt-Release Technology

The Elegoo Saturn 4 Ultra uses the so-called tilt-release technology. By "tilting" the resin tank after each individual layer, the models can be released from the release film much more easily and quickly. At the same time, higher speeds of up to max. 150 mm/h are achieved, and you can switch between two printing modes as needed for more flexibility and efficiency:

  • Fast print mode,
  • Slow print mode.

Combined light source for more detail

The Saturn 4 Ultra uses Elegoo's proprietary lighting technology that combines a COB light source with a Fresnel lens collimator. This produces a 405 nm wavelength light beam and illuminates the screen at a right angle with a light angle of less than 5°, resulting in a field of view uniformity of more than 92%. This results in highly precise prints with detailed surfaces, sharp corners and edges.

Intelligent functions

The smart resin printer is equipped with advanced features to ensure an effortless, user-friendly start and a worry-free printing experience at all times:

Automatic levelling with one click: Automatic levelling allows you to start printing immediately after unpacking. An intelligent mechanical sensor allows the build plate to be levelled every time without any worries.

One-Click Self-Check: Perform a quick self-test and checks whether individual components of the resin printer are working properly.

Intelligent mechanical sensor: To prevent possible damage to the LCD screen (e.g. caused by foreign objects) and to detect resin defects and levelling errors, the printer is equipped with a special mechanical sensor that supports the residue detection function. The reliable detection system ensures greater safety and better printing results.

AI Camera Intelligent Detection

With an integrated AI camera, you always have error detection and real-time printing status in view. The smart camera detects both empty building plates and printing errors such as model distortions. Nothing stands in the way of smooth, high-quality printing.

Additionally, you get the opportunity to make time-lapse videos of your creations and share them with the 3D printing world as you wish.

User-friendly design

The resin printer is also designed with some user-friendly details to make your printing process as pleasant and uncomplicated as possible:

  • Quick-release design of the build plate,
  • Resin tank with two outlet openings for easier pouring of the resin,
  • Drip tray that prevents the resin from leaking out,
  • Replaceable tank cap,
  • Hinged lid for effortless access,
  • Laser-engraved build plate for better adhesion and easier removal of the model.

Other useful features:

  • Robust metal housing for precise printing results,
  • Compatibility with MARS MATE Air Purifier for effective removal of resin odours and VOCs,
  • PFA release film with excellent release performance and a non-stick surface for easier removal of the printed models,
  • Simultaneous management of multiple 3D printers,
  • 8G RAM for stable and faster data transfer,
  • User-friendly, capacitive 4-inch touchscreen with intuitive operation.
