How much space does it need?

The Elegoo Saturn 3 Ultra measures 305.9 × 273 × 562.5 mm (12 × 10.7 × 22.1 in) for a 218.88 × 122.88 × 260 mm (8.6 × 4.8 × 10.2 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 15% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

Which projects is it for?

The Saturn 3 Ultra targets users who want 12K resolution on a 218.88 × 122.88 × 260 mm build volume per Elegoo, suited to detailed miniatures, game pieces, and regular batches of small parts.

The advertised speed of up to 150 mm/h, reached with Elegoo's Rapid Standard Resin and the included ACF release film, targets users who print often and want to cut the wait between batches.

Materials and setup

The 10-inch 12K mono screen at 11520 × 5120 pixels targets XY accuracy advertised at 19 × 24 µm per Elegoo, with a COB light source paired with a reflector to reduce light dispersion and keep printed surfaces smooth.

The built-in Linux system with 4 GB of ROM handles WiFi transfer (2.4G and 5G, 6-10 Mbps) via a detachable antenna, for a more stable workflow than a typical embedded system per Elegoo.

What the bundle includes or not

Elegoo advertises a plug-in air purifier, an all-metal body for durability, and 4-point leveling that only needs one initial setup. Exact accessories included (starter resin, spare ACF film) should be checked on the retailer's listing.

The low-release-force ACF film, with a frosted side and a smooth side, is presented by Elegoo as the key part for reaching the advertised top speed with Rapid Standard Resin.

Alternatives to compare

For a more compact 9K screen, the Mars 4 is a more affordable option within Elegoo's lineup. For professional large-format resin, the Form 4L targets heavier use.

The resin printer buying guide helps compare the Saturn 3 Ultra's 12K resolution against 9K or 16K screens based on the detail level you need.

Frequently asked questions

What is the build volume of the Elegoo Saturn 3 Ultra?

Elegoo lists a 218.88 × 122.88 × 260 mm (8.6 × 4.8 × 10.2 in) build volume (width × depth × height). That is the largest theoretical part size; supports, brim and orientation reduce the usable space.

How big is the Elegoo Saturn 3 Ultra?

According to Elegoo, the Elegoo Saturn 3 Ultra measures 305.9 × 273 × 562.5 mm (12 × 10.7 × 22.1 in) (width × depth × height) and weighs 12 kg (26.5 lb). Leave extra clearance for the spool, cables and airflow, and more if you add a multicolor unit.

What resolution does the Elegoo Saturn 3 Ultra offer?

Elegoo lists a 10-inch 12K LCD and 19 µm XY resolution. Finer pixels help with miniature detail, but supports, resin and washing still decide the final surface.

Do you need Elegoo's resin to reach 150 mm/h?

Elegoo advertises this top speed with its Rapid Standard Resin paired with the included ACF film; other third-party resins may print more slowly depending on their profile.

Does the all-metal body change anything day to day?

It improves the machine's robustness and durability per Elegoo, useful for frequent use or a shared workshop.

Is 4-point leveling enough over time?

Elegoo advertises a one-time leveling process using clockwise-tightening screws, with no need to recalibrate before every print.
