ELEGOO Saturn 4 Ultra 16K Resin 3D Printer, Heated Tank, 150mm/h, Wi-Fi

Who it suits

The Saturn 4 Ultra 16K is for people who already know resin is their hobby: miniature painters, tabletop gamers and model makers who want to fill a larger plate with very detailed parts in one run. Its 10-inch 16K screen resolves detail at 14 × 19 µm, and reviewers praised its miniatures highly.

Why it scores 7 for ease of use

It has most of what makes resin less hands-on. It levels itself, alerts you to low resin or cured residue in the vat, sends files over Wi-Fi, and watches prints with an AI camera. The vat heats resin to 30°C, which matters in the UK: cold resin is thick and a common cause of failed prints in garages and sheds, and one reviewer kept printing successfully in a studio close to freezing.

It misses the point for a built-in air filter, and like every resin printer it carries our 2-point deduction for washing, curing, gloves and ventilation. That leaves a Medium difficulty rating: it is about as easy as resin printing gets, but resin printing is never effortless. Read resin safety, ventilation and disposal before buying.

Printing with it

Tilt release, which peels each layer away from the film at an angle, lets it print at up to 150 mm of height per hour. The 211 × 118 × 220 mm build volume holds a lot of miniatures at once, or larger busts and display pieces.

Living with it

A 10-inch machine needs more space, a larger vat of resin and a bigger wash and cure setup than a 7-inch printer. The 4-inch touchscreen is a resistive type. See whether a wash and cure station is worth it and when to replace the release film.

Is today’s price a good deal?

Check the listing is the 16K model: the Saturn 4 Ultra is also sold in a 12K version at a different price. If you are new to resin, compare it with the smaller, cheaper ELEGOO Mars 5 Ultra in our review table.
