I have been attempting to 3D print a flower that I designed using SketchUp. This is a screen shot of what the file looks like… …however, when I actually print the object, it comes out with the octagon missing, but the two circles are printed… …Here is a picture of the file in SketchUp, and then the 3D printed version of it. …I made sure to make it all into a group before exporting as an STL file. I made sure every side was white as well. I don’t understand why this is happening. Any help would be much appreciated. Thanks!
Can you share the model for inspection?
Make sure face normals are correct, back side is mixed bag?
You can use the Solid Inspector extension to help sanity-check your objects before sending off to 3d print:
If entity info doesn’t say Solid Group or Solid Component you will have to clean up your geometry.
It is only 2 clicks with SuSolid plugin.One for deleting all internal faces and other for reversing all reversed faces.
+1 on @tt_su Solid Inspector. Love that tool! Check out my article on my recommended plugins for 3D printing http://www.mastersketchup.com/best-3d-printing-plugins-for-sketchup/
