Elegoo Saturn 4 Ultra 12K - Resin 3D Printer

12K Resolution. Tilt Release Speed. Large-Format Resin — Redefined.

The Elegoo Saturn 4 Ultra 12K doesn't ask you to choose between resolution and speed. With 11,520 × 5,120 pixel resolution across a 10-inch monochrome LCD and Tilt Release Technology that dramatically accelerates layer separation, it delivers both staggering detail at a pace that keeps your production moving.

That 12K resolution means each pixel is exceptionally small, translating directly into surface quality and fine detail that pushes the limits of what desktop MSLA printing can achieve. Miniature facial features, jewelry filigree, dental model geometry, mechanical threads — the Saturn 4 Ultra 12K renders them with clarity that's immediately visible and measurable under a lens.

The 218.88 × 122.88 × 220mm build volume gives you the room to print large single-piece models, full plate batches of smaller parts, or multi-component assemblies in a single run. Auto-leveling removes the most common source of first-layer failure, and power-loss recovery means a power interruption doesn't have to mean a scrapped print.

Whether you're running a professional production workflow or leveling up from a smaller desktop resin machine, the Saturn 4 Ultra 12K is built to handle the output.

Purpose-built for detail and scale — perfect for:

• Tabletop miniatures, wargaming armies, and character figures with fine sculpted detail
• Jewelry prototyping and casting masters — rings, pendants, settings, and filigree patterns
• Dental models, clear aligner bases, surgical guides, and medical visualization
• Scale architectural models and interior design mockups with surface texture and fine detail
• Large figurines, busts, and collector pieces printed in a single run
• Engineering prototypes and functional parts requiring tight tolerances and a smooth finish
• Batch production of smaller, detailed parts across a full build plate
• Product designers and studios who need presentation-quality prototypes at speed

Printer Compatibility: Compatible with standard 405nm MSLA photopolymer resins.

Safety Note: Resin printing involves handling liquid photopolymer resin. Use nitrile gloves, work in a well-ventilated space, and follow proper resin disposal procedures. Uncured resin is a skin and eye irritant.
