💡About the Elegoo Saturn 4 Ultra

The Elegoo Saturn 4 Ultra 16K is a professional-grade MSLA (masked stereolithography) resin printer featuring 16K monochrome LCD resolution and an integrated heating tank that maintains resin at 30°C for consistent results. It delivers exceptional detail for miniatures, jewelry, dental models, and engineering prototypes. Important: resin printing requires IPA washing and UV curing post-processing — not recommended as a first 3D printer.

  • 16K resolution — 15µm XY accuracy

    The Saturn 4 Ultra 16K's 16K LCD delivers detail that FDM printers cannot match — ideal for miniatures, jewelry masters, and precision engineering prototypes.

  • Fast mono LCD curing

    Monochrome LCD screens cure resin in 1-3 seconds per layer, dramatically faster than older RGB screens.

  • Large build volume for resin class

    212×118×220 mm is large for a resin printer — enabling batch printing of miniatures or larger single-piece models.

🎯Who is this for?

Miniature painters, jewelers, dental technicians, and designers who need micron-level detail that FDM printing cannot achieve — and who are prepared for the post-processing workflow of resin printing.

FAQs

Is resin printing right for me?

Resin printing delivers extraordinary detail but requires significant post-processing: prints must be washed in IPA (isopropyl alcohol) and cured under UV light. Liquid resin is a skin irritant and requires gloves, ventilation, and proper disposal. Resin is not recommended as a first 3D printer — start with FDM and move to resin when you have a specific need for its detail level.

Can I compare the Saturn 4 Ultra to FDM printers?

FDM and resin are fundamentally different technologies suited for different purposes. FDM excels at large, functional parts in engineering materials. Resin excels at small, highly detailed parts. We do not compare resin and FDM printers directly on this site.

What post-processing does resin printing require?

After printing: (1) wash parts in IPA or a dedicated wash solution to remove uncured resin, (2) cure under UV light (a UV curing station is recommended), (3) remove supports and sand if needed. Allow ~20-30 minutes of post-processing per print.
