Prusa SL1S Speed - LCD Resin Printer

The Prusa SL1S SPEED is a resin 3D printer designed to offer high-resolution prints with great production speed, ideal for design professionals, engineering, dentistry, jewelry, and rapid prototyping. Thanks to its UV light photopolymerization technology through a 5.96" monochrome LCD screen and 2560×1620p resolution, this printer guarantees superior definition in each layer.

Furthermore, the SL1S offers a build volume of 127 x 80 x 150 mm, has a motorized tilting bed to prevent layer skipping, a resin level sensor, and a rear fan with a carbon filter to minimize odors during the manufacturing process.

The SL1S SPEED from Prusa incorporates a new optical system and a powerful UV LED matrix that allow reducing the exposure time per layer to just 1.4 seconds, which translates into a printing speed up to three times faster than its predecessor, the SL1. With this improvement, it is possible to print objects up to 150 mm in height in just three hours, without losing quality or detail.

The rigid aluminum structure offers excellent stability during printing, eliminating vibrations and allowing work with complex geometries, even with thin walls, with high precision. The quick release system and the automatic Z-axis calibration further improve the user experience, reducing downtime and ensuring layer-by-layer reliability.

This professional resin 3D printer is fully compatible with standard 405 nm resins, allowing work with a wide variety of materials. In addition, its full integration with PrusaSlicer, Prusa's official slicing software, allows optimizing print profiles, generating automatic supports, and applying advanced functions such as hollowing, a technique that allows emptying a 3D model to save material and time.

The SL1S SPEED is aimed at both professional users and laboratories, hospitals, design workshops, and industries that require precise and fast 3D prints, with low operating costs and specialized technical support. By maintaining its open-source philosophy, this resin printer guarantees total flexibility in the workflow and in the choice of materials.

The new Prusa is available in two versions and can be purchased individually or together with the CW1S curing and washing station to complete a professional resin 3D printing ecosystem.

CW1S Station, much more than washing and curing

The CW1S allows performing four essential functions in a single unit: resin preheating, washing with isopropyl alcohol using a magnetic stirring system, drying of the printed model, and uniform UV curing, thus ensuring that each part reaches its maximum strength and surface quality.

Thanks to its intelligent and compact design, even smaller than the SL1S itself, this station not only saves space in the workshop but also streamlines and professionalizes the entire manufacturing process. Using the CW1S together with the SL1S SPEED allows obtaining more precise, cleaner, and more durable results, becoming an ideal solution for those seeking efficiency, quality, and ease in the post-processing of resin 3D prints.
