ELEGOO Saturn 4 Ultra 16K Resin 3D Printer Features

16K Ultra-High Precision Printing

Equipped with a 10-inch 16K mono LCD, the Saturn 4 Ultra redefines detail in resin printing. Models are reproduced with lifelike textures, smooth finishes, and incredible accuracy, making it ideal for intricate miniatures, prototypes, and jewelry designs.

Smart Tank Heating at 30°C

One of its standout features is the smart resin tank heating system, which maintains resin at an optimal 30°C. This prevents bubbles, improves fluidity, and enhances layer adhesion—significantly reducing print failures and ensuring consistent quality.

AI Camera with Built-in Lighting

The integrated AI camera enables real-time monitoring of every print. It instantly alerts users to issues like empty build plates or warped models, while the built-in chamber lighting allows for convenient inspections, day or night. Additionally, the time-lapse function makes it easy to document and share printing progress.

Auto-Leveling, Plug-and-Play Simplicity

Gone are the days of tedious manual leveling. The Saturn 4 Ultra 16K features one-click auto-leveling, ensuring precise calibration right out of the box. This user-friendly setup makes it approachable for both beginners and professionals.

Tilt Release Innovation for Faster Prints

Smart Sensors for Safer Printing

With built-in mechanical sensors, the Saturn 4 Ultra detects resin residue, preventing potential LCD damage. It also provides timely alerts for resin shortages or leveling issues, ensuring efficiency and minimizing wasted material.
