Elegoo Mars 5 Ultra vs Phrozen Sonic Mighty 4K
Technical comparison · Resin 3D printing
Two mid-range resin printers for the same job, and the choice comes down to fine detail versus part size: the Mars 5 Ultra states a finer XY resolution, the Sonic Mighty 4K a much larger plate. The figures on this page are manufacturer-declared values.

| 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 ensures broad compatibility with the main third-party slicing software programs available on the market, including widely used solutions such as ChiTuBox and Lychee Slicer. File management is primarily handled via offline transfer using the USB port located on the front of the chassis, or by utilizing the wired Ethernet network connection for remote monitoring within a local network. There are no restrictions or dependencies on proprietary cloud platforms, allowing users to work in complete autonomy and protect the intellectual property of their print files without requiring an active internet connection during the manufacturing process. |
The differences that matter
- Price → €249 versus about €575: the Sonic Mighty 4K costs about €325 more, and that money buys plate size, not finer detail.
- Plate → 200×125 mm versus 153×78 mm: a 20 cm part fits on the Sonic Mighty 4K; on the Mars 5 Ultra anything over 15 cm gets split.
- XY resolution → 18 µm versus 52 µm: small lettering and curved surfaces look crisper on the Mars 5 Ultra.
- Connection → the Mars 5 Ultra has Wi-Fi, the Sonic Mighty 4K has USB and Ethernet: files sent from the PC over the network on one, a USB stick or network cable on the other.
Which one to choose
Choose Mars 5 Ultra if…
you print tabletop miniatures, busts or small objects with raised lettering and curved surfaces, and detail is the first thing you check. The trade-off is room: a long or wide part has to be split and glued, and only a few figures fit on the plate at once.
Choose Sonic Mighty 4K if…
on Monday morning you need one part that would have to be cut up on the Mars 5 Ultra, or you want to fill the plate with several models in a single run, up to 220 mm tall. You pay for it in fineness: small lettering and curves come out less crisp, and the machine costs more than twice as much.
