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.

Our Fastest Printer Ever

With our 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.

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.

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

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.

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, our 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.

Original Prusa CW1S

CW1S is a post-processing device for resin-based 3D prints. The CW1S is a 4-in-1 device, which makes the otherwise long and messy process a breeze. What it can do?

WASHING

The finished print has to be washed to remove the uncured resin from its surface. CW1S uses a stainless steel tank for isopropyl alcohol and a magnetic propeller. The magnetic propeller movement stirs the liquid, so it gets to every part of the model. This method is less aggressive compared to ultrasonic cleaning and works very well even with very small objects.

DRYING

Drying a washed model is yet another feature of the multipurpose CW1S. Before the washed model is cured with UV-light, it has to be dried in order to avoid resin residue stains.

CURING

Curing the model with UV-light is an essential part of the resin printing process. Printed objects are usually soft, so treating them with UV light gives them optimal surface properties.

Resin Pre-heat

Resins tend to change their state while being stored, that is the reason to shake the bottle with resin well before printing. However, CW1S can also preheat the resin before printing it, thus getting it to the ideal printing temperature and state for the best performance of the SL1S and the resin itself.
