Elegoo Saturn 4 Ultra: specs, power draw and resin print cost calculation

The Saturn 4 Ultra is Elegoo's resin (MSLA) printer with a high-resolution monochrome LCD, built for precise miniatures, jewelry masters and functional parts.

Key specs

• Build volume: 211.68 × 118.37 × 220 mm.
• Screen: 10" monochrome LCD, 11,520 × 5,120 resolution (12K), XY resolution 19 × 24 µm.
• UV light source: 405 nm wavelength — the standard for most photopolymer resins.
• Power draw: 144 W maximum per the power supply's rating — noticeably lower than large-format FDM printers, since there's no large heated bed.
• Vat heating: a built-in system keeps resin temperature around 30°C — useful in cold rooms or with seasonal temperature swings.

Who it suits

• Printing miniatures, jewelry masters, dental and functional parts requiring high detail.
• Shops where resin printing complements an FDM fleet for orders with surface-finish requirements.

What to watch for in cost calculation

Beyond the printer's own power draw, resin print cost should budget resin itself, isopropyl alcohol for washing, UV post-curing, and regular FEP film / consumable LCD screen replacement — expense lines that FDM printing doesn't have.
