The Original Prusa SL1S SPEED is a professional SLA resin 3D printer. It is an upgraded version of the manufacturer’s open-source MSLA machine — . Being a device of the new generation, the SL1S provides several important improvements, including a superior monochrome display, enlarged build area, advanced LCD cooling system, and a variety of modern technologies that make 3D printing easier, safer, and more convenient than ever before.

The Original Prusa SL1S SPEED is aimed at increased performance, fast print speed, professional-level quality, and low running costs. To achieve these purposes, the machine is equipped with a motorized tilting bed that makes for faster printing and improved reliability, resin tank with automatic sensor for smart material management, enhanced network features, and capacious build volume for efficient production.

Among quality-of-life features provided by the Original Prusa SL1S SPEED 3D printer are: Trinamic drivers with auto-homing function that are responsible for the machine’s silent operation, a rear fan with a built-in carbon filter minimizing resin odors around the printer, potent cooling that improves overall performance and extends lifespan of the device, safety vat under the tilt mechanism to protect the internal parts against minor resin spills, and fully-featured network interface for advanced control. The open material system allows using a wide range of consumables with different properties to get the desired outcomes.

Due to its ability to produce top-quality, highly detailed models in a rapid, convenient, and cost-effective way, the Original Prusa SL1S SPEED 3D printer is perfect for personal and professional applications in various spheres, including prototyping, jewelry, artistic modeling, medical use, and more.

To make work with the printer even more effective, it is possible to order an optional post-processing device by Prusa — CW1S. It is a 4-in-1 machine, which makes the resin printing process much easier. The CW1S can wash, dry, and cure a printed model as well as preheat resin before using it. You can select the device in the “Add-ons and extras” menu.

Print quality

The Original Prusa SL1S SPEED model can print layers with heights ranging from 10 to 100 microns due to the printer’s completely redesigned optics and new monochrome display technology. Engineered with a powerful 5.96" monochrome LCD with a physical resolution of 2560 x 1620 p, the device provides a vastly improved print quality compared to its predecessor. Thus, one can produce accurate models with smooth exterior surfaces and a high level of detail.

To further improve quality and stability of printing, the SL1S model is built with a rigid, heavy aluminum body, which minimizes vibrations and ensures the best possible performance even when printing thin and highly detailed geometry.

Moreover, the printer is equipped with a quick-release mechanism that maintains the Z-axis calibration, meaning there is no need to recalibrate the machine when the platform with the print is removed.

Taking into account the above mentioned features, one can expect premium-level quality of the printed items inherent to all Prusa devices.



The Original Prusa SL1S SPEED 3D printer features universal material compatibility. The machine can consistently print with a wide range of 405 nm UV resins ensuring outstanding dimension accuracy, surface quality, and low deformation rate, which is particularly great for complex and highly detailed models, just like the ones in the photos below.


Build volume

The Original Prusa SL1S offers a large build area of 5 x 3.15 x 5.9 inches (127 x 80 x 150 mm), which is 25% bigger compared to the SL1 model. This lets you produce a single large model or a wide variety of small-to-medium sized prints in batches without the need of splitting them, which makes for time-saving and increased productivity.

According to the developer, the largest object that fits in the printer’s build area can be finished in under 4 hours with 0.05 mm layer height or in 2 hours with 0.1 mm layer height. This is also possible due to the faster tilt of the print bed compared to the SL1.


Printer controls and software

The Original Prusa SL1S SPEED 3D printer features USB, Wi-Fi, and LAN connectivity. It can be easily controlled through a web browser or convenient full-color touchscreen with a clear menu structure and user-friendly interface. The on-screen Assisted Wizard will guide you through the whole setup and calibration process.

The device is powered by the internally developed and regularly updated PrusaSlicer software offering a number of useful tools, such as hollowing, automatic support generation, easy object manipulation, and others. With ready-to-use factory-tested material profiles, the program ensures perfect results with different resins and significantly reduces print preparation time.

The slicer is available for Windows, Mac, and Linux. It works with the most common 3D file formats.
