You learned how to use the Ruler/Protractor tool so that you can do precision modeling, and reviewed how to create colored and textured objects. Now it's time to get to the core of this book and make a printer-ready 3D model in Blender. This chapter teaches you how to make models that are watertight, manifold, and will print well.
The following are the topics we'll be covering in this chapter:
- Using the 3D Print Toolbox panel and the Mesh Analysis panel
- Selecting the units to use
- Making a model watertight
- Making a model manifold
- Dealing with distorted faces and sharp edges
- Economizing-getting the most object for the least cost
Blender has always been able to make models suitable for 3D printing. But starting with Blender 2.67, they included two new tools that make it much easier, the Mesh Analysis panel and the 3D Print Toolbox panel. We'll look at both of them and then use them to make sure our model is fit for 3D printing.
