Elegoo Saturn 4 Ultra 16K

The Elegoo Saturn 4 Ultra 16K is a desktop resin printer built on a 10-inch 16K monochrome LCD, aimed at display miniatures, busts and casting masters. Against the 12K Saturn 4 Ultra it adds a finer pixel, a heated vat and a camera with its own light.

Build volume is 211.68 × 118.37 × 220 mm, the panel packs 15120 × 6230 pixels at 14 × 19 μm, Z accuracy 20 μm, layer height 0.01–0.2 mm. Tilt release with PFA film pushes it to 150 mm/h: the vat peels away at an angle, peel force drops, the next layer starts right away. The tank holds resin at 30 °C, leveling is automatic, and a 1920 × 1080 camera watches the job.

Pros

• Detail reads as factory plastic: GamesRadar couldn't tell prints from cast Games Workshop parts, scoring it 5/5
• Prints pop off the laser-engraved plate without a scraper — Goonhammer's main takeaway from the machine
• Heated vat saves a cold room: 3DWithUs printed at −3 to 4 °C with no base-layer failures
• First run takes minutes: it joins Wi-Fi, pulls firmware and levels itself
• Tilt release hits 150 mm/h and treats the film more gently than a vertical lift
• Camera light makes overnight time-lapses and failure detection usable; plate tabs grip well with gloves on

Cons

• No air filtration and no USB purifier port — you need ventilation or a separate Mars Mate; reviewers call it the main gripe
• The gain over 12K is barely visible: Goonhammer figures you'd need to be 17 mm away to catch the 5 μm difference
• Build area is smaller than the 12K version (211.68 × 118.37 vs 218.88 × 122.88 mm), and sliced files don't transfer between them
• The tilting vat and self-levelling plate are a pain to clean, and the drip tray is flimsy — Goonhammer's broke on the second use

It makes sense for display figures and busts from 75 mm up, casting masters, dental parts and small technical components. Beginners can handle it too: automation covers leveling and resin temperature, leaving ventilation and a wash-and-cure station to you.

Bottom line: a predictable workhorse with strong automation — detail and speed in exchange for no air filtration and a fussy-to-clean vat.
