| 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 system supports file formats generated by major third-party slicing software, including ChiTuBox and Lychee Slicer, ensuring operational flexibility for users with established workflows. Connectivity is comprehensive, featuring Ethernet cable options, Wi-Fi connection, and a USB port for offline file transfer. The internal firmware efficiently manages calibration and function control via the integrated touchscreen interface. Despite the availability of the Phrozen GO mobile application for remote progress monitoring, the machine operates entirely autonomously and does not require a constant internet connection or reliance on proprietary cloud services to execute and complete daily print operations. |
The differences that matter
- Price: the Sonic Mighty 8K costs about €250 more
- XY resolution: the Saturn 4 Ultra 16K is rated at 19 µm versus 28 µm on the Sonic Mighty 8K
- Print speed: the Saturn 4 Ultra 16K reaches 150 mm/h versus 70 mm/h
- Lift system: tilt on the Saturn 4 Ultra 16K, standard FEP on the Sonic Mighty 8K
Which one to choose
Choose Saturn 4 Ultra 16K if…
you want finer resolution (19 µm vs 28 µm) and shorter print times (150 mm/h vs 70 mm/h), while saving about €250. The tilt lift system also reduces stress on the FEP compared to the Sonic Mighty's standard peel.
Choose Sonic Mighty 8K if…
you already have resins or accessories tuned for the Phrozen ecosystem, or prefer standard FEP over tilt: on the available technical data there's no other reason to pay €250 more than the Saturn 4 Ultra 16K.
