| Software notes | The system natively supports files generated by the most widespread industrial and commercial slicing applications, such as ChituBox and Voxeldance Tango. Built-in networking features allow for remote monitoring and file transfers via integrated Wi-Fi or a dedicated Ethernet interface, simplifying deployment within connected digital manufacturing pipelines. Firmware updates are regularly released by the manufacturer via downloadable files for USB installation, ensuring continuous optimization of curing algorithms and broad compatibility with newly developed photosensitive polymer resins. | The device natively supports the proprietary ChituBox preparation software and is fully compatible with popular third-party slicers in the industry. File management and remote monitoring are handled via the desktop application connected to the local Wi-Fi network. Advanced functions of the integrated camera enable automatic time-lapse video generation and anomaly identification during the placement of initial layers. File transfer is not bound to mandatory proprietary remote servers, ensuring operational continuity offline via the USB port. |
The differences that matter
- Price: €899 vs €399 → the Saturn 4 Ultra costs €500 less.
- Plate: 302.4×161.98 mm vs 218.88×122.88 mm → the Jupiter 2 fits more miniatures per print or longer parts.
- Declared XY resolution: 26 µm vs 19 µm → the Saturn 4 Ultra is declared finer on detail.
- Weight: 40 kg vs 14.5 kg → the Jupiter 2 needs a fixed bench, the Saturn 4 Ultra moves more easily.
Which one to choose
Choose Jupiter 2 if…
you fill the plate with miniatures to print a whole set in one run, or make parts up to about 300 mm long. The Jupiter 2 costs €899, weighs 40 kg and needs a fixed spot; its declared XY resolution is 26 µm.
Choose Saturn 4 Ultra if…
you print miniatures and parts that fit in 218.88×122.88 mm and don't want to spend €899: the Saturn 4 Ultra costs €399, weighs 14.5 kg and declares 19 µm XY resolution. It is easier to move around, but long prints have to be split.
