In this recipe, we'll learn how to use filters in MeshLab to prepare our scan for printing. First, we'll learn how to take the layers we merged with the align tool and flatten them into one unifying shell. Then, we'll use another filter to reconstruct the surface and fill holes. The last filter we'll use will decimate the mesh and simplify it for printing.

Getting ready

You'll need your aligned mesh open in MeshLab. If you are opening the mesh from an .mlp MeshLab project file, make sure that you have the Align Tool window open, and select Glue Here all Meshes from the alignment options. One of the quirks of MeshLab is that the alignment meshes are saved unglued.
