I just got my first 3D printer (SLA type). I launched Sketchup and designed a random object to test the printer (see attachment please). The object was exported to .stl file and opened in ChituBox then sliced. Tracing the slices shows that “walls” in my object have no thickness (hollow)!
I wonder how to make solid walls for 3D printing?
