      About the Author

      Joe Larson, known online as the 3D Printing Professor, is one part artist, one part mathematician, one part teacher, and one part technologist. It all started in his youth, doing BASIC programming and low-resolution digital art on a Commodore 64. As technology progressed, so did Joe's dabbling, eventually taking him to 3D modeling while in high school and college, and he momentarily pursued a degree in computer animation. He abandoned that and instead became a math teacher, and then moved to software development for 10 years before returning to education, teaching technology in college.

      When Joe first heard about 3D printing, it took root in his mind, and he went back to dust off his 3D modeling skills. In 2012, he won a Makerbot Replicator 3D printer in the Tinkercad/Makerbot Chess Challenge, with a chess set that assembles into a robot. Since then, his designs on Thingiverse have been featured on Thingiverse, Gizmodo, Shapeways, Makezine, and other places. He currently produces weekly videos about design for 3D printing on his YouTube channel, http://www.youtube.com/user/mrjoesays.

      About the Reviewer

      Marcus Ritland is a designer and 3D printing consultant in his small business, Denali 3D Design. Since 2008, he has been providing 3D modeling and 3D printing services as well as moderating the SketchUcation 3D printing forum (http://sketchucation.com/).

      He has volunteered at a local makerspace, teaching SketchUp classes and leading 3D printing meetups. As an author of 3D Printing with SketchUp, he is currently on a quest to eliminate design-for-3D printing illiteracy.

      Preface

      3D printers have arrived! Complex and beautiful objects are available at the touch of a button in our schools, libraries, or even our homes. Whether or not you have a 3D printer, learning how they work and how to design for them is the best way to be a part of this new industrial age. And the best part is it doesn't cost a penny to learn to design for them.

      This book will teach you the things you need to know about 3D printers. Then, you will use the robust and free software, Blender, to follow step-by-step instructions through several planned projects. You will gain the tools, techniques, and skills you need to make your own projects that you can print by yourself on a 3D printer near you and share with others online to print around the world.

      What this book covers

      Chapter 1, 3D Printing Basics, will help you understand 3D printing basics, types of 3D printing, and how FFF printers work.

      Chapter 2, Beginning Blender, will introduce Blender, how to set it up, and some basic and mid-level functionality. Knowing the content of this chapter will get you over Blender's infamous learning curve and provide the basic knowledge and reference necessary for following along with future projects.

      Chapter 3, The Octopus Pencil Holder, building this simple project, an octopus pencil holder, will involve simple selection techniques and modification commands of basic shapes in Blender's Edit mode, and applying modifiers to soften and combine shapes. This technique alone can be used to make an unlimited number of cool things once mastered.

      Chapter 4, Measuring Basics, mentions how it is very important that accurate measurements must be made when planning and applied to the modeling of a 3D object. In this chapter, we deal with different techniques of taking measurements: measuring with a ruler or calipers, the grid paper trace method, and 3D scanning.

      Chapter 5, An SD Card Holder Ring, walks you through the process of making a cool 3D printed project—an SD card holder.

      Chapter 6, Sculpting the Face of the Sun, teaches you how
