UV LED Assembly SL1S Prusa3D

The official UV LED assembly for Prusa SL1S is a key component that enhances resin curing with precision and efficiency in every print.

Specifically designed for the SL1S, it includes the complete LED assembly along with the custom lens. This system provides higher curing power and optimal UV light distribution, resulting in faster and more detailed prints. The new system offers greater UV power and an improved optical design that enhances curing control, optimizing the final quality of printed parts.

Compared to the SL1 model, the UV LED panel features a new LED array that is four times more powerful. Achieving an optimal combination of screen type, position, UV LED size, lens, and other elements—even with standard 405 nm resins—it is possible to achieve exposure times as short as 1.6 seconds per layer, and even down to 1.4 seconds for small parts and transparent resins.

This opens new possibilities: resins that previously required 20–30 seconds now cure in 3–4 seconds, which is highly useful in industrial applications ranging from automotive to medical fields. The SL1S goes far beyond printing miniatures: it can compete with equipment costing two to three times more. The SL1S is already used in sectors such as medicine (IKEM), automotive (Škoda Auto), and medical training (NEU3D Labs).

Its assembly is simple and straightforward, following Prusa’s official instructions, facilitating replacement even in demanding work environments and continuous production.
