Elegoo Mars 4 Ultra vs Elegoo Saturn 4 Ultra 16K
Technical comparison · Resin 3D printing
Two resin printers with nearly identical XY resolution, 18 and 19 µm, and the same 150 mm/h speed: what changes is the size of the plate. The Saturn costs €70 more and offers more than twice the surface.

| Software notes | The system utilizes an open software ecosystem, ensuring compatibility with the main slicing programs on the market, including ChituBox and Voxeldance Tango. The machine integrates built-in Wi-Fi connectivity for the remote transfer of print files via the official application or compatible software, eliminating the need to use physical USB drives for every operation. The internal firmware is based on an optimized version of Linux, which improves the responsiveness of the user interface on the built-in touch screen display and optimizes the handling of complex data originating from 9K files. Exposure parameters and resin profiles can be managed directly from the chosen software, offering precise control over curing times and axis movement speeds. | 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 differences that matter
- 153 × 78 mm plate, 165 mm high → 219 × 123 mm, 220 mm high: the Saturn takes more than twice as many pieces per print and a part up to 22 cm tall.
- €329 → €399: the €70 buys almost only surface, since XY resolution is practically the same.
- 7.1 kg and 22.7 cm on a side → 14.5 kg and about 33 cm: the Mars fits on a small desk, the Saturn wants more room.
Which one to choose
Choose Mars 4 Ultra if…
You print miniatures and small detailed parts on a 153 × 78 mm plate, up to 165 mm tall, for €329. The trade-off: a narrow plate, where larger batches have to be split over several prints, and nothing wider than 78 mm on the short side.
Choose Saturn 4 Ultra 16K if…
You print a bigger batch of miniatures, or a larger part, in a single job on a 219 × 123 mm plate up to 220 mm tall, for €399. The trade-off: 14.5 kg against 7.1 and a footprint of about 33 × 33 cm, almost 10 cm more on a side.
