Elegoo Saturn 4 Ultra 16K Resin 3D Printer

Elegoo Saturn 4 Ultra 16K — Professional Resin 3D Printer

The Saturn 4 Ultra 16K is Elegoo's flagship resin printer, delivering the finest detail available in a desktop MSLA machine. Its 16K mono LCD achieves 14×19μm XY resolution — sharp enough for the most demanding miniature, jewellery, dental, and industrial prototype work. Tilt-release technology pushes speeds up to 150mm/h, while a smart heated resin vat and AI monitoring camera keep production reliable.

Key Features

• 16K Mono LCD (10"): 15,120×6,230 resolution at 14×19μm pixel size — the highest resolution available in a production desktop resin printer
• 150mm/h Print Speed: Tilt-release technology for fast model peeling without sacrificing detail; switchable fast/slow modes
• Smart Tank Heating at 30°C: Maintains optimal resin viscosity for consistent layer adhesion and reduced defects — particularly valuable in cooler environments
• AI Camera with Chamber Light: Real-time monitoring, failure detection, time-lapse recording, and print farm management via Wi-Fi cluster printing
• One-Click Auto Levelling: Fully automatic — no manual adjustment required
• Smart Mechanical Sensor: Residue detection protects the LCD; alerts for resin shortage and levelling failures
• Power-Loss Resume: Picks up exactly where it stopped after power interruption
• One-Click Self-Test: Pre-print component check for consistent results
• COB Light Source + Fresnel Collimating Lens: Uniform, accurate UV curing across the full build area
• Section Exposure Tuning: Fine-tune exposure time per section for optimal results on complex models
• Wi-Fi + Ethernet: Remote management and print farm control
