I’m a newbie to 3D printing. Downloaded an Stl file, am getting nonmanifold edges. Only PC bambu studio can fix automatically. Naturally I have a mac. Can anyone explain what I need to fix? I know I can create a PC on the mac, want to understand manifold edges.
Non-manifold geometry is defined as any edge shared by more than two faces. This can occur when a face or edge is extruded but not moved, which results in two identical edges directly on top of one another.
So basically you have overlapping edges that cannot be printed.
Thank you. I would never have guessed that meaning.
After importing a car model exported from Archicad in STL file format, I encountered the same error message. I have a partial understanding of the issue, but could you kindly explain the possible reasons behind the absence of layers in the preview model?
