Elegoo Saturn 3 Ultra vs Elegoo Saturn 4
Technical comparison · Resin 3D printing
The two resin printers share the same 218.88×122.88 mm plate and the same 19 µm XY resolution. What remains is price, about €549 against about €309, and what sits underneath: peel film and lift speed.

| Software notes | The device offers flexible connectivity manageable via integrated wireless network or standard USB port, facilitating the transfer of print files without physical proximity constraints. It natively supports the main formats generated by the most popular slicing software in the resin 3D printing landscape, such as CHITUBOX and Voxeldance Tango, ensuring full compatibility and flexibility in the digital workflow. The proprietary firmware ensures smooth management of settings directly from the touch screen interface integrated on the machine. Since no mandatory dependencies on closed cloud platforms are found, the user maintains total control over their files and local print preparation, guaranteeing maximum data privacy and operational continuity even without an internet connection. | 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
- Price about €549 vs about €309 → €240 difference for the same plate and resolution.
- Stated speed 150 vs 70 mm/h → on a 6 cm model, about 24 vs 51 minutes of ideal lift alone.
- Wireless network and USB vs USB only → on the Saturn 3 Ultra you send the file without carrying a stick around.
Which one to choose
Choose Saturn 3 Ultra if…
you print tall parts in batches and machine time matters. The Saturn 3 Ultra states 150 mm/h and uses an ACF film: a 6 cm model needs about 24 minutes of ideal lift, against about 51 at 70 mm/h (manufacturer-stated values; real times depend on exposure). You accept paying about €240 more for the same plate and resolution.
Choose Saturn 4 if…
you print miniatures or small parts and want the same plate and the same 19 µm for about €309. You accept the lower stated speed of 70 mm/h, standard FEP instead of the ACF film, and files that arrive over USB only.
