Specifications

The Elegoo Saturn 3 Ultra is an MSLA (Masked Stereolithography) resin 3D printer, which means some of the technical specifications you asked about: specifically hotends, nozzles, and multi-material printing: do not apply to this machine . Instead of melting solid plastic filament through a nozzle, it uses a UV light source to cure liquid photopolymer resin layer by layer [1, 4].
