Elegoo Saturn 3

The Elegoo Saturn 3 is a mid-size resin printer built around a 10-inch 12K monochrome LCD. It's the step up from the Mars line: a tray of miniatures, a large bust or an enclosure part in one run. Don't mix it up with the Saturn 3 Ultra — tilting vat, ACF film and Wi-Fi.

The panel resolves 11520 × 5120 with non-square pixels — 19 μm on X, 24 μm on Y. Build volume is 218.88 × 122.88 × 250 mm, layer height 0.01–0.2 mm, Z accuracy 0.02 mm, top speed 70 mm/h on a vertical lift with PFA film. A COB source behind a Fresnel lens keeps the 405 nm beam within 5° at over 90% uniformity. It weighs 11 kg and reads files off a USB stick.

Pros

• Fine texture comes through: The Gadgeteer resolved 0.15 mm features, with fabric folds and miniature faces sharp off the plate
• A 218 × 123 × 250 mm field fits a whole tray of minis or a full-height bust in one run
• Exposure stays even across the plate: the COB and Fresnel lens keep the beam within 5° at 90%+ uniformity, so corners print like the center
• The laser-carved plate grips well, and a big knob with a square socket lets you pull and clean it in one go
• 9H tempered glass shields the LCD, and 3D Printerly calls the cooling — six copper tubes, four fans — quiet

Cons

• Leveling is manual, two screws on a ball joint: 3DWithUs lost five prints in a row before finding the bundled card too thick, then leveled against the film and raised bottom layers from 2 to 6
• No network at all, just USB, and the port sits on the side panel where it's awkward to reach
• 70 mm/h is middling today: the Saturn 3 Ultra with a tilting vat and ACF film is twice as fast for a small premium
• Small stuff adds up: the lid isn't hinged, so there's nowhere to park it with resin-covered gloves; the UI is dated and lists four files at a time; the bundled purifier is token at best

People buy the Saturn 3 for capacity: batches of miniatures, busts, master models, cosplay parts printed in sections. A beginner can manage it, but manual leveling and per-resin exposure tuning come with it.

Bottom line: an honest workhorse with 12K detail and a big plate for modest money, paid for with manual setup, USB instead of a network and average speed.
