PrusaSlicer has a fairly simple user interface. The majority of the screen is dedicated to the 3D view, which is used to manipulate 3D models. The top toolbar (1,2) is used to add and remove objects. The left toolbar (4) has tools for manipulation with 3D models, such as the scale or rotate tool. The right panel is used mainly to select a print, filament and printer profile (6,7,8) and to choose whether or not to generate supports or brim.
The “Slice now” button (5) is used to generate G-code, which can then be exported to an SD card or sent directly to a printer. Some of the advanced functions are hidden by default, you can enable them later by switching to the Advanced or Expert mode (12).
