Introduction

In this chapter, we're going to take the models that we scanned with 123D Catch and make them better. We'll do this by using another free program offered by Autodesk called Meshmixer. It's a 3D modeling program that offers a variety of sculpting tools that manipulate the surface mesh of a 3D model. It also offers a series of tools that are geared to optimize a model for 3D printing.

We'll also take a look inside the model. There's a lot that can happen in the interior, which can affect both the structural integrity and surface quality. We'll see how infill options in both Slic3r and Skeinforge can be adjusted for different uses.
