3D printer Elegoo Saturn 4 8K — large build volume, resin LCD MSLA

ELEGOO Saturn 4 Ultra 3D Printer is a resin MSLA printer designed for high-detail and high-speed printing. It features a 10-inch 12K monochrome LCD (11520 x 5120 pixels) with a 19 x 24 µm XY resolution, a COB light source with a collimating Fresnel lens, and Tilt Release Technology for rapid model separation. The printer includes an automatic leveling system, intelligent mechanical and liquid-level sensors, AI camera monitoring, and a 4" capacitive touchscreen for control. The build volume is 218.88 x 122.88 x 220 mm and supported layer thickness ranges from 0.01 to 0.2 mm.

Advantages

The Saturn 4 Ultra combines very high XY resolution and a large 10" 12K Mono LCD to reproduce fine details while maintaining a substantial build volume. Tilt Release Technology reduces peel time and enables printing speeds up to 150 mm/h. Uniform illumination from the COB + Fresnel lens system ensures smooth surfaces and consistent curing across the print area. Built-in sensors, automatic leveling and an AI monitoring camera simplify setup, detect problems during printing, and enable automatic resume after power loss.

Suitable for

• High-detail miniatures and models
• Dental and medical model prototyping
• Product prototypes and small-series production
• Hobbyist and professional resin printing

How to use

Place the printer on a stable, level surface and connect the power supply and optional WiFi antenna. Install the build plate and resin tank following the included user manual. Pour the recommended resin into the tank up to the indicated level; the built-in sensor will monitor the liquid level. Use Chitubox or Autodesk Fusion to prepare and slice models, then transfer the file via USB or WiFi. Start a print from the 4" touchscreen; the printer will perform automatic leveling and component checks. Monitor prints with the AI camera and pause or stop if errors are detected. In case of power interruption, the printer can resume the job after power is restored.

Usage recommendations

Use resins compatible with MSLA printing and follow manufacturer guidelines for exposure settings. Wear the included protective mask and gloves when handling uncured resin and use the supplied funnel and resin tray for safe pouring and disposal. Perform regular maintenance: clean the resin tank and build plate after prints, inspect the LCD protection layer for damage, and tighten spare screws as needed.
