Elegoo Mars 5 Ultra vs Elegoo Saturn 4 Ultra
Technical comparison · Resin 3D printing
Two resin printers with the same screen technology and the same declared resolution, so the choice comes down to how much build plate you need. The Mars 5 Ultra is the compact one, the Saturn 4 Ultra the larger format.

| Software notes | Machine control and management rely on a flexible and modern software ecosystem. The device natively supports leading industry slicing programs, including ChituBox and Voxeldance Tango, ensuring extensive customization of printing parameters. Integrated Wi-Fi connectivity allows for remote monitoring and file transmission via cloud functionalities or cluster management, streamlining the workflow in multi-unit laboratory environments. The proprietary firmware handles real-time error notifications, such as resin shortage or residues in the vat, interfacing directly with the touchscreen display to guide the user through operational troubleshooting independently and safely. | 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
- Build plate: 153.36 × 77.76 mm against 218.88 × 122.88 mm → the Saturn prints larger parts or more parts at once; on the Mars the 77.76 mm short side is the limit.
- Build height: 165 mm against 220 mm → tall parts have to be cut on the Mars.
- Price: €249 against €399 → the Mars costs €150 less.
Which one to choose
Choose Mars 5 Ultra if…
you print small parts and want the machine on a desk: it takes up 26 × 26.8 cm and weighs 8.8 kg. Anything longer than its plate has to be split into several pieces.
Choose Saturn 4 Ultra if…
you fill the plate with several parts per run or print objects that will not fit on the Mars. Expect more bench space (32.7 × 32.9 cm, 14.5 kg) and €150 more; in return you get a built-in camera for time-lapse and for checking the first layers.
