The sturdy construction and sleek industrial design reflect ELEGOO’s commitment to building long-lasting machines.
Massive 16K Mono LCD Screen
The highlight of this model is its 10-inch 16K Mono LCD, which enables extreme detail and resolution in every print.
Advantages:
- Ultra-high resolution (15360 x 8640 pixels) for microscopic detail.
- Sharper edges and smoother surfaces compared to 8K or 12K models.
- Increased durability thanks to mono LCD technology, which lasts longer than RGB screens.
This makes it perfect for industries and creators needing professional-quality miniatures, prototypes, dental models, or figurines.
Large Build Volume
With a build area of 8.33 x 4.66 x 8.66 inches, the Saturn 4 Ultra strikes the balance between precision and size.
Benefits of the larger volume:
- Print bigger models in one go.
