The Original Prusa SL1 uses MSLA, which means that there is an LED array as it’s light source (405 nm) in combination with an LCD photomask to shape the light image. The SL1 is completely Open Source and therefore has full support for Liqcreate as 3rd party resin. The SL1 is able to reach a minimum layer height of 0.01 mm, but the recommended layer height by Prusa is 0.025-0.100 mm. The following settings are optimized for Liqcreate resins.
