Elegoo Saturn 4 vs Phrozen Sonic Mighty 8K
Technical comparison · Resin 3D printing
Two resin printers with the same build plate (about 218×123 mm) and the same stated speed, 70 mm/h. What changes is the price, 309 € against 650 €, and how they connect: USB only on the Saturn 4, plus Wi-Fi and Ethernet on the Sonic Mighty 8K.

| Software notes | The machine is supported by major slicing software on the market, including optimized profiles for CHITUBOX and VoxelDance Tango, ensuring broad operational flexibility. The system relies entirely on USB connection for file transfer and offline printing, eliminating any dependency on cloud services. The onboard interface is managed via a practical 3.5-inch resistive touchscreen that allows users to start prints, monitor basic parameters, and utilize automated diagnostic features, such as the initial self-check of mechanics and sensors. | 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 309 € vs 650 € → the Saturn 4 costs about 340 € less for the same plate and stated speed.
- USB only vs USB, Wi-Fi and Ethernet → on the Sonic you print without carrying the stick around.
- XY resolution 19 µm vs 28 µm (manufacturer's stated values) → finer detail on the Saturn 4.
- Height 220 mm vs 235 mm → slightly taller parts fit on the Sonic.
Which one to choose
Choose Saturn 4 if…
Saturn 4: it costs about 340 € less and states 19 µm XY resolution. Files arrive on a USB stick and you start them from the 3.5-inch touchscreen, which works if the printer sits next to the computer. The trade-off: no network, so every job goes through the stick.
Choose Sonic Mighty 8K if…
Sonic Mighty 8K: it takes files over Wi-Fi or an Ethernet cable and you follow progress in the Phrozen GO app, handy if the printer is in another room. Usable height rises to 235 mm against 220 mm. The trade-off: about 340 € more and a stated 28 µm resolution against 19 µm.
