SL1S Prusa3D LCD Screen

The 5.96″ monochrome screen designed for the Prusa SL1S SPEED represents a major breakthrough in resin printing, significantly improving performance and precision. With a physical resolution of 2560×1620 pixels, this screen achieves superior UV transmission by using a monochrome liquid crystal matrix.

Unlike RGB panels, this screen allows layer exposure times as short as 1.4 seconds with standard 405 nm resins, resulting in prints up to three times faster than the original SL1. Additionally, its lifespan is approximately 2000 hours, compared to the ~500 hours of RGB LCDs.

To leverage monochrome technology, Prusa completely redesigned the optics, UV LED layout, and system lens, optimizing light collimation and uniformity—critical factors to ensure consistently high-quality and detailed prints.

This panel not only speeds up curing but also delivers visibly improved detail definition, ideal for both industrial prototyping and small-scale production. Furthermore, when combined with the fast tilt bed mechanism, it enables printing objects up to 150 mm tall in just 3 hours.

In summary, the monochrome screen for SL1S offers a faster, more precise, and more durable printing experience, providing professionals and enthusiasts with a robust solution aligned with modern production demands.
