The SL1S Speed 3D resin printer is a newer model from Prusa that offers some distinct advantages over the CW1S. One of the most significant advantages is its speed: the SL1S can print up to three times faster than the CW1S, making it a better choice for businesses requiring high volumes of prints. In addition, the CW1S is substantially cheaper than the SL1S, making it a better entry-level option for a new business operation or experiment.
