Elegoo Saturn 4 Ultra 16K
Sharp 16K resin printer for miniatures with heated vat and AI cam
Researched by Riley Hart · updated Oct 30, 2026
Is the Elegoo Saturn 4 Ultra 16K worth it? The Saturn 4 Ultra 16K prints very fine detail with a 10 inch 16K screen, a heated vat and an AI camera that flags failed prints. It costs $650 as of Nov 4, 2026, and GamingTrend scored it 100/100.
The Saturn 4 Ultra 16K prints very fine detail with a 10 inch 16K screen, a heated vat and an AI camera that flags failed prints. It is a strong pick for miniatures, figurines and jewelry models, and the current $399 sale price is low for this class. Skip it if you cannot ventilate a room for resin fumes or you want large, tough functional parts, which suit an FDM printer better.
Best for: miniatures and fine detail models. Skip if: you cannot ventilate for resin fumes.

What independent reviewers found
- Printed a chess set at 0.05 mm layers and 2.3 s exposure, with pieces taking 2 h 26 min to 3 h 7 min each and supported figurines 1 h 23 min to 1 h 56 min. Prints stuck firmly and showed sharp detail. Downsides were the 16.1 kg weight and a touchscreen only emergency stop.
- CNX Software
- Called it the best consumer 3D printer on the market by a large margin. Ready to print in about 10 minutes, vat preheat took about 10 minutes and print time estimates were accurate. Noted slicer software is not quite ready and the 16K gain over 12K is hard to see.

Questions buyers ask
Is the 16K worth it over the 12K Saturn 4 Ultra?
GamingTrend says the detail gain is hard to see without a microscope, but it still rated the 16K very highly. Buy whichever is cheaper if you print mostly larger models.
Do I need a wash and cure station?
Resin prints must be washed and UV cured. A station like the Mercury Plus 3.0 makes this easier; CNX Software saw it at $129.99.
What resins can it use?
Elegoo lists standard, water washable, ABS like, plant based and tough 405 nm resins.
