The Original Prusa SL1 3D printer can produce objects with an incredible amount of detail – tiny wrinkles on cloth of a figure, texture of skin, thin railings on buildings, etc. However, in case the printed object is missing small details (not entire parts of the model), it can be due to incorrect exposure times.
Make sure you are using the correct preset for your color/resin in PrusaSlicer!

Insufficient exposure
Too short exposure times will result in details being “melted” together. Increase the exposure times to recommended values to fix this issue.
Overexposed layers
Long exposure times will result in a “staircase” effect – the layers won’t blend into each other perfectly and some details may be lost due to this effect. Use the recommended exposure time values to fix this issue.
