Elegoo Mars 5 Ultra vs Elegoo Saturn 4
Technical comparison · Resin 3D printing
Two resin printers €60 apart, with almost the same declared XY resolution (18 and 19 µm). What decides it is the plate: 153.36×77.76 mm on the Mars 5 Ultra, 218.88×122.88 mm on the Saturn 4.

| 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 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 differences that matter
- Plate: 153.36×77.76 mm vs 218.88×122.88 mm → the Saturn 4 fits more than one extra row of miniatures.
- Declared print speed: 150 mm/h vs 70 mm/h → the Mars 5 Ultra finishes the same part height sooner.
- Price: €249 vs about €309 → the Mars 5 Ultra costs €60 less.
- Peel system: tilt vs standard FEP → the Mars 5 Ultra separates the layer from the vat in a different way.
Which one to choose
Choose Mars 5 Ultra if…
you print miniatures and small parts in frequent batches: the Mars 5 Ultra costs €249 and declares 150 mm/h against the Saturn 4's 70 mm/h, so the same full plate finishes sooner. The limit is the smaller plate, which holds fewer parts per print.
Choose Saturn 4 if…
you want more parts on the same plate or parts that don't fit in 153 mm: the Saturn 4 has 218.88×122.88 mm and costs about €309. You accept the lower declared speed and carrying files over on USB, since the machine doesn't connect over the network.
