ELEGOO Saturn 4 Ultra 12K resin 3D printer for detailed, high-throughput prints

The ELEGOO Saturn 4 Ultra 12K is a resin 3D printer built to deliver high-resolution parts, faster print cycles, and reliable day-to-day operation. It combines a 10-inch monochrome LCD, a large build area, and a uniform COB light source to support precise results for both professional and hobby use.

Take your 3D printing to the next level with a machine designed for precision, speed, and reliability across detailed model work, production runs, and creative projects.

Key features that affect print detail, speed, and consistency

• 12K print resolution for fine detail: The 10-inch monochrome LCD provides 11520 × 5120 resolution, helping the printer reproduce intricate features, crisp edges, and refined surfaces with strong accuracy.
• Large-format build capacity: A build volume of 218.88 mm × 123.12 mm × 250 mm gives more room for larger parts or multiple models in one session, which is useful for batch printing and bigger assemblies.
• Fast exposure times: The ELEGOO Saturn 4 Ultra 12K achieves layer exposure times as low as 1.5 seconds, reducing overall print time while maintaining the machine's stated focus on quality output.
• Uniform curing across the plate: The COB light source is designed to provide even exposure across the build plate, helping reduce print artefacts and supporting improved surface finish consistency.
• Built for regular use: A sturdy metal body and durable LCD design support long-term use and stable performance in workshops, studios, and production environments.
• Straightforward operation: The 3.5-inch touchscreen and advanced slicing software simplify setup, monitoring, and print control, making the system easier to use for both beginners and experienced users.

Who the ELEGOO Saturn 4 Ultra 12K is for

The Saturn 4 Ultra is suited to users who need detailed resin output and a practical build volume in the same machine.
