## What reviewers found

### Elegoo Saturn 4 Ultra 16K

- CNX Software: 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.

- GamingTrend (100/100): 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.

### Formlabs Form 4

- Tom's Hardware: Editor's Choice. A test town printed in 44 min at 50 microns with very clean detail. A Rocket Bust took 4 h 59 min versus 3 h 13 min on an Elegoo Saturn 4 Ultra, but with slightly more refined detail. [Source](https://www.tomshardware.com/3d-printing/formlabs-form-4-review)
- TechRadar (5/5): Editor's Choice. Nine Benchys printed in about 1 h 12 min with supports versus about 7 h 10 min on a Creality K1C. About 8 liters of resin ran without an issue, and PreForm generated supports gave a 100% success rate. [Source](https://www.techradar.com/pro/formlabs-form-4-review)
