Elegoo Saturn 4 Ultra 16K - Resin 3D Printer

The Pinnacle of MSLA Resolution. Built for the Finest Detail.

The Elegoo Saturn 4 Ultra 16K is the flagship of the Saturn 4 Ultra range — and the resolution proves it. Where the 12K delivers exceptional detail, the 16K pushes further, capturing the finest surface texture, the sharpest edges, and the most intricate geometry that desktop resin printing can produce. If your work demands the absolute limit of what MSLA technology can resolve, this is the machine.

The 16K monochrome LCD allows for faster layer curing than conventional screens, keeping print times efficient without compromising on the surface quality that makes resin printing worth choosing over FDM in the first place. A dual linear rail Z-axis ensures smooth, precise vertical movement throughout the full print height — minimizing layer lines and delivering consistent results from the first layer to the last, even on tall models.

Wide resin compatibility means you're not locked into a proprietary material ecosystem. Standard and specialized 405nm UV resins — ABS-like, water-washable, flexible, castable, dental, and high-temp formulas — all work with the Saturn 4 Ultra 16K, giving you the material flexibility to match the right resin to every application.

The flagship choice for resolution-critical work — perfect for:

• Tabletop miniatures and wargaming figures where every sculpted detail needs to read cleanly
• Jewelry design and casting masters — the 16K resolves filigree, prong settings, and engraving that lesser machines blur
• Dental models, clear aligner bases, surgical guides, and prosthetic components requiring the tightest dimensional accuracy
• Scale architectural models and detailed interior design mockups
• Collector figurines, busts, and character models where surface quality is the finished product
• High-end prototyping for product designers and studios requiring presentation-grade output
• Batch production of small, highly detailed parts across a full build plate

Printer Compatibility: Compatible with a wide range of standard and specialized 405nm UV 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.
