Fixing Model Problems

One of the issues facing 3D modellers is the ability to create models perfectly suitable for 3D printing. A correct visual appearance does not mean it will print correctly, because the design might be ambiguous, have non-printable shapes or be "leaky" (non-watertight). Shapeways writes:

I've found that it's often difficult to retrofit your existing models for 3D printing, so it's best to start from scratch and with each step keep the goal (3d printing) in mind. This is especially true for models that you find online in model libraries - these are often made for visualization, not for 3d printing. Fixing these for 3D printing will make you want to pull your hair out!
