I had just received a review copy of 3D Printing Blueprints by Packt Publishing. This is a book by Joe Larson. 3D Printing Blueprints covers ways of using Blender, a free 3D modelling program, to build 3D models for physical printing and prototyping.
I will be writing the review soon. In the meantime, you can get more information about this new Blender 3D and 3D Printing-related book via their website at http://www.packtpub.com/3d-printing-blueprints/book
