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. We also offer an upgrade kit for your SL1.

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.

High-Quality Materials and Rigid Body

We have built the Original Prusa SL1S 3D printer 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.

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.

List of Features

• Quick-release platform - maintains calibration. No need to recalibrate the printer when the platform with the print is removed.
• Assisted Wizard for quick and easy setup and calibration
• Motorized tilting bed - prevents layer shifts, stirs the resin, enables faster printing, improves reliability
• Resin tank with non-proprietary FEP films - easy and cheap replacement, low running costs
• Silent operation with Trinamic drivers (auto-homing function)
• Advanced LCD cooling system improves performance and extends the life of internal components
• Rear fan with a carbon filter to minimize odors around the printer
• Safety features: resin level sensor, safety vat under the tilt mechanism to protect the internal parts against minor resin spills
• Fully-featured network interface: control your printer through your web browser
