Elegoo Saturn 4 Ultra 16K

Elegoo Saturn 4 Ultra 16K Resin 3D Printer

The Elegoo Saturn 4 Ultra 16K sets a new benchmark in MSLA resin 3D printing. Featuring a massive 10-inch 16K monochrome LCD screen paired with an ultra-fine 14 × 19 μm XY resolution, this machine captures miniature details, skin textures, and crisp geometry with unmatched clarity. Combined with innovative Tilt Release technology, integrated smart resin heating, and AI camera error detection, the Saturn 4 Ultra 16K makes high-speed, ultra-high-definition resin printing faster, cleaner, and virtually foolproof.  

Key Features:

• 16K Monochrome Ultra-Resolution LCD: Boasts a display resolution of 15,120 × 6,230 pixels and a 14 × 19 μm XY accuracy. It reproduces microscopic surface textures, tiny text, and sharp miniature edges with virtually no layer lines.  
• High-Speed Tilt Release Mechanism: Instead of lifting the Z-axis up and down between every layer, the resin vat tilts dynamically to detach cured layers smoothly. This slashes layer cycle times, boosting printing speeds up to 150 mm/h.  
• Smart Tank Resin Heating (30°C): Maintains resin fluid temperatures at an optimal ~30°C. Pre-heating reduces resin viscosity, preventing print failures, layer bubbles, and layer separation caused by cold environments.  
• True Plug-and-Play Auto Leveling: Features factory-set self-leveling bed sensors - no manual paper tuning or leveling screws required.  
• AI Smart Camera & Real-Time Monitoring: Features an onboard AI camera that automatically detects empty build plates, model warping, or detachment mid-print. Automatically records time-lapses and alerts you if errors occur.  
• COB Light Source & Fresnel Lens: Delivers uniform 405 nm UV light across the entire build plate with a tight light divergence angle, ensuring consistent layer curing edge-to-edge.

 Supported Materials

Works with standard 405 nm UV-curable resins, including:

• Standard & High-Speed Resins: Rapid-curing resins for fast miniature prototyping.  16K / 8K
• High-Precision Resins: Formulated specifically to capture microscopic surface details.
• ABS-Like & Tough Resins: For impact-resistant functional prototypes, brackets, and snap-fit parts.
• Water-Washable Resins: For easier cleanup without heavy isopropyl alcohol (IPA) usage.
• Plant-Based & Low-Odor Resins: Eco-friendlier options for indoor work areas.
• Castable Dental & Jewelry Resins: High-accuracy resins designed for lost-wax casting workflows.  

Pro Tip:

Take advantage of the printer's smart resin tank heating feature on cold days. Letting the printer preheat the resin tank for 5 to 10 minutes before initiating the print significantly lowers resin viscosity, resulting in smoother flow, fewer layer separation voids, and cleaner fine details on miniature prints.

Together, Layer by Layer!
