In this chapter, you were introduced to the 3D Print toolbox and Mesh Analysis panel. You have learned how to make a model watertight and manifold so that it will print properly. Distorted polygons and sharp edges shouldn't be a problem for you anymore. You found out how to control the costs of 3D printing by minimizing the volume of the material in the model.
In the next chapter, you will discover proper building techniques to make a model strong, light, and precise. You will learn how to deal with overhanging polygons, reorient your object if needed, and how to output the file in STL and X3D formats.
