Elegoo Saturn 4 Ultra
The Elegoo Saturn 4 Ultra is a 2024 MSLA resin printer: a 10-inch 12K mono LCD at 11520 × 5120, a 218.88 × 122.88 × 220 mm build volume, a tilt-release vat rated up to 150 mm/h, a monitoring camera, Wi-Fi and automatic Z zeroing through a force sensor.
Owners land here with four recurring topics: early LCD failure (the panel carries a three-month warranty), false force-sensor alarms such as “Foreign matter detected” and “Auto-leveling failed”, knocking from the tilt mechanism, and resin leaking into a chassis that cannot be sealed because the vat assembly has to move.
