Elegoo Saturn 4 Ultra 16K vs Phrozen Sonic Mini 8K S
Technical comparison · Resin 3D printing
The Saturn 4 Ultra 16K offers a build area almost twice as large (218.88×122.88 mm vs 165×72 mm) and Wi-Fi remote control; the Sonic Mini 8K S costs about €75 less and stays USB-only. The choice comes down to how many parts you need per print and how much remote control matters.

| Software notes | The system natively supports ChituBox proprietary slicing software, widely adopted in the resin printing industry, ensuring smooth management of supports and exposure parameters. The machine integrates Wi-Fi connection modules that enable remote management and workflow monitoring. Compatibility with open formats ensures operational flexibility with leading third-party programs, allowing users to optimize printing profiles based on the specific resins used, whether standard or engineering-grade. | The machine offers broad compatibility with leading third-party slicing software options, notably popular solutions like Chitubox, Lychee Slicer, and Voxeldance Tango. This software flexibility prevents users from being locked into a restrictive, closed proprietary ecosystem, allowing them to utilize advanced support generation and model orientation algorithms. File transfer is handled entirely offline via a standard USB port, a design choice that prioritizes connection stability during data transmission but lacks native Wi-Fi connectivity or cloud-based management features. Material profiles are easily accessible and customizable, significantly streamlining the fine-tuning of exposure times for a wide variety of commercial 405nm photopolymer resins available on the market. |
The differences that matter
- Build area: 218.88×122.88 mm vs 165×72 mm → the Saturn 4 Ultra 16K prints much larger or more numerous parts.
- Price: €399 vs ~€324.5 → the Sonic Mini 8K S costs about €75 less.
- Declared XY resolution: 19 µm vs 22 µm → the Saturn 4 Ultra 16K renders slightly finer detail.
- Connectivity: Wi-Fi on the Saturn 4 Ultra 16K, USB only on the Sonic Mini 8K S → only the Saturn 4 Ultra 16K allows remote control.
Which one to choose
Choose Saturn 4 Ultra 16K if…
Anyone printing more parts per batch or wider models gets a build area of 218.88×122.88 mm on the Saturn 4 Ultra 16K, nearly double the Sonic Mini 8K S, plus Wi-Fi remote control. The trade-off is a €399 price, about €75 more.
Choose Sonic Mini 8K S if…
Anyone printing single miniatures or small batches and wanting to save gets the Sonic Mini 8K S at about €324.5, €75 less than the Saturn 4 Ultra 16K. You give up more than half the build area (165×72 mm vs 218.88×122.88 mm) and Wi-Fi, staying on USB.
