The Saturn 4 Ultra 16K by Elegoo is a high-resolution MSLA (Masked Stereolithography) 3D printer designed for fast and precise fabrication of micro- to mesoscale components using UV-curable photopolymer resins.
It uses a mono LCD masking screen and UV LED light source (405 nm) to cure photosensitive resins layer by layer, enabling detailed 3D parts with smooth surfaces and fine features.

Available Resins:
Standard photopolymer resin (general purpose)
Note: Users may bring their own resin, but its use must be approved by facility staff to ensure safety, compatibility, and cleanroom compliance.
