The Original Prusa SL1S SPEED is here! Compared to the original SL1, the new SL1S offers vastly improved print quality, a 25% larger print area, and up to three times faster printing with only 1.4 second exposure time per layer. Short exposure times combined with the built-in tilt mechanism enable you to print up to a 150mm tall object in three hours.

The SL1S is the perfect choice for producing extremely detailed 3D prints - fast! No matter whether you want to produce highly detailed sculpts, design and prototype, or you need a reliable workhorse for your workshop or lab, the SL1S delivers outstanding results across the board.


Main Features

Great Print Quality

The SL1S features a new 5.96'' monochrome LCD with a physical resolution of 2560×1620p. Taking advantage of the completely reworked optics and the new monochrome display technology, the SL1S offers a vastly improved print quality compared to its predecessor.

Prusa's Fastest Printer Ever

With custom-made optics system and completely reworked UV LED panel, the SL1S can easily reach a 1.4 second exposure time per layer with standard 405nm resins. This is especially useful for small-scale production or prototyping projects - you can print more in less time.

High Printing Speed, Amazing Details

Featuring a high-resolution 5.96'' LCD monochrome display (2560×1620p) and reworked optical system with four times more powerful UV LED panel, the SL1S produces even more detailed 3D prints. Common 405nm resins require only 1.4 seconds of exposure time per layer. Short exposure times enable much easier use of advanced materials.

High-Quality Materials and Rigid Body

The Original Prusa SL1S 3D printer has been built around a rigid, heavy aluminum body, which minimizes vibrations and ensures the best possible printing performance even when printing thin and highly detailed geometry. The SL1S features a quick-release mechanism, which maintains the Z-axis calibration.

For Newcomers and Professionals

The SL1S is more than just a machine for producing figures and statues. With professional-level print quality, extensive documentation, low running costs and 24/7 tech support, the SL1S is perfect for newcomers and professionals alike. Its predecessor, the SL1, already found its way to hospitals and industrial companies.

Full Support in PrusaSlicer

The SL1S is fully supported in the latest releases of PrusaSlicer, their internally developed and regularly updated slicing software. Take advantage of hollowing, automatic support generation, easy object manipulation and many other tools. PrusaSlicer also contains factory-tested profiles for dozens of resins.

Touch Controls, Network Features and more

Upload your print files over network and perform over-the-air firmware updates. The SL1S comes packed with modern technologies that make 3D printing easier, safer and more convenient than ever before. On-screen wizard will guide you through the whole setup process. You will be ready to print in no time!

Open-source with Support for 3rd party Resins

Just like all the Original Prusa i3 3D printers, the SL1S is also completely Open Source! This means (among other things) full support for 3rd party resins (405nm). No proprietary vats, resins or FEP films! You can buy 3D printing supplies anywhere you want.

Warranty info

The pre-assembled Original Prusa SL1S printer is covered for 12 months for businesses and educational customers.

Wear and tear category components and consumables are excluded from this warranty. The warranty period begins with the day when the customer receives the goods.

WARNING: The exposure display and the FEP foil fall into the category of normal wear and tear components, which are not covered by our standard warranty. Instead, the warranty of the exposure display covers a maximum of 2000 hours of printing - the SLA 3D printing process on the Original Prusa SL1S is considered the standard way of using and wearing the original display. The warranty of the FEP foil covers 10 cycles (print jobs). When used properly in accordance with the instructions in the official guides (such as the SL1S 3D printing handbook), the life expectancy of the FEP foil is several times longer.

Neither the Seller's liability for defective products nor the quality warranty applies to printers or parts damaged by handling, which is in conflict with the instructions and recommendations in the official manuals and guides, or improper handling caused by unofficial modifications, such as modifications to hardware or software.
