Basic Rules, Tips and Tricks

Wall Thickness

In 3D Printing, wall thickness refers to the distance between one surface of your model and the opposite sheer surface. Wall thickness can either provide you with a strong solid surface, or with a flexible and expandable surface. A good example of when creating thin surface walls is ideal is when designing a spiral that needs some suspension properties. This makes your design light and flexible. The opposite effect can be achieved by making your surface walls thicker. This would be ideal for a more solid spiral-inspired flower vase.

Polishing on the Inside

As already mentioned, small polishing stones are used to make the surface of your model smoother. However, because of the size of the stones, they can easily get stuck inside small holes. Therefore, we recommend that any openings that need polishing be larger than 6.5 mm in diameter. This helps avoid the problem of the stones getting stuck inside your model. Also note that the inside of your model will always be less polished than the outside - in fact, your model will not be polished at all on the inside if the holes are smaller than 6.5 mm because the stones won't be able to enter.
