3D printing with RepRap Cookbook

By: Salinas

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.

Creating a hollow model with MeshLab

Creating a hollow model with MeshLab is not about repair issues, but it is about the modifications necessary for proper preparation of a model that is intended for a commercial 3D printing service. Most of these services charge by calculating the volume of material required to print the design. In this case, by making a model hollow, it will decrease the volume of material necessary and greatly decrease the cost of the print job.

Getting ready

You'll need MeshLab and the support test model we made in Chapter 6, Making the Impossible. It looks like the following image:

Getting ready

How to do it...

We will proceed as follows:

  1. Select the Show Layer Dialog icon.
  2. Go to Filters and select Remeshing, Simplification, and Reconstruction. Scroll down to the next cascaded window and select Uniform Mesh Resampling.
  3. From the pop up, change the Precision (abs and %) field to 1.0 in World Unit. Change Offset (abs and %) to -3.0. Check Clean Vertices and Multisample. Click on Apply...
