Overview of this book

A systematic guide consisting of over 100 recipes which focus on helping you understand the process of 3D printing using RepRap machines. The book aims at providing professionals with a series of working recipes to help make their fuzzy notions into real, saleable projects/objects using 3D printing technology. This book is for novice designers and artists who own a RepRap-based 3D printer, have fundamental knowledge of its working, and who desire to gain better mastery of the printing process. For the more experienced user, it will provide a handy visual resource, with side-by-side comparisons of the two most popular slicers, Skeinforge and Slic3r. A basic understanding of designing and modeling principles and elementary knowledge of digital modeling would be a plus.

Using MeshLab for fixing normals

In this recipe, we're going to learn how to use MeshLab to visually inspect and correct the face normals of a model. MeshLab has a good collection of tools to repair and modify face normals. Using the selection tools, we'll be able to choose the faces we want to repair.

Getting ready

You'll need MeshLab and the extended capsule file model that you modified with SketchUp in the previous recipe.

How to do it...

We will proceed as follows:

  1. Load the model in MeshLab. MeshLab indicates inverted normals by displaying the faces in black. We can see this in the following image:
    How to do it...
  2. Let's take a look at the normals. We can do this in MeshLab by selecting Render in the menu and then Show Normal/Curvature from the list. Not only does MeshLab display the face normals (blue lines), but it also displays the vertex normals (violet lines).
  3. Go to the icon tray and select the Flatlines view.
  4. The inverted normals are difficult to see, so choose Wireframe for the view...
