- Break down complex geometries into multiple simple shapes and model them in layers using Blender
- Design, manipulate, and export 3D models for 3D printing with Blender
- Master the art of creating meshes, scaling, subdivision, and adding detail with the Boolean modifier as well as sculpting a custom shape
- Cut a model into small pieces and understand how to design complex interlocking joints that form a part of a jigsaw puzzle
In Detail
3D printing has revolutionized the way that global industries conceptualize and design products for mass consumption. Considered as the next “trillion-dollar” business, every industry is in the race to equip its personnel with techniques to prototype and simplify complex manufacturing process. This book will take you through some simple to complex and effective principles of designing 3D printed objects using Blender.
There is a comprehensive coverage of projects such as a 3D print-ready octopus pencil holder, which will teach you how to add basic geometric shapes, and use techniques such as extruding and subdividing to transform these shapes into complex meshes. Furthermore, you'll learn to use various techniques to derive measurements for an object, model these objects using Blender, organize the parts into layers, and later combine them to create the desired object with the help of a 3D printable SD card holder ring design project. The final project will help you master the techniques of designing simple to complex puzzles models for 3D printing.
Through the course of the book, we'll explore various robust sculpting methods supported by Blender to create objects. You'll move, rotate, and scale the object, and manipulate the view. You'll edit objects with actions such as bends or curves, similar to drawing or building up a clay structure of different shapes and sizes. By the end of the book, you will have gained thorough practical hands-on experience to be able to create a real-world 3D printable object of your choice.
Style and approach
This is a hands-on guide to the world of 3D printing. With the help of simple to complex projects, you'll learn various techniques to design 3D printable objects using Blender.

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 to use the sculpting tools in Blender to transform a basic shape into a complicated design.
Chapter 7, Cutting a 3D Jigsaw Puzzle, further modifies the model created in the previous chapter by creating the puzzle pieces and then applying their shape that to the sculpted model model to create the individual pieces, combining two of Blender's powerful editing styles to create a finished product.

Chapter 1. 3D Printing Basics
As cool as 3D printing is, there is a lot of hype around it, which sometimes causes confusion. Before starting to design for 3D printing, it's best to know a little bit about 3D printing technologies.
3D printing is a limitless technology in the sense that there is no end to the things it can make. Still, that doesn't mean that it can make anything without limitations. 3D printing can make things that no other manufacturing method can, but it has rules that need to be followed to ensure success. There are different types of 3D printing as well, and each type comes with its benefits and drawbacks:
In this chapter, we'll discuss:
What is 3D printing?
3D printing is cool. It seems as if not a day passes without another mention of 3D printing online in the news and media. Everyone is getting excited about 3D printing. But when you look deeper, it seems as if everything is being 3D printed, and anything could be. Does 3D printing something make it better? What exactly is 3D printing?
In many ways, 3D printers are just tools, the same as any that you'd find in a wood shop or garage. These tools make cool things, but not on their own, and just because something is made with, say, an electric drill press, that doesn't automatically make it better than something that isn't. It's the things that people, like you, are doing with these tools that make them cool.
I'm not saying that 3D printing isn't cool by itself. 3D printing lets you create things, test them, change their design, and try something new quickly until you get it right. It makes things of incredible complexity and, because it's additive manufacturing, generates comparatively little waste. The availability of cheaper and faster 3D printers means that there's a chance that there's a 3D printer near you.
What defines 3D printing?
There are many different types of 3D printers, but what makes them all similar is that they build solid shapes from layers of materials, starting with an empty build area and filling it with the print. This is called additive manufacturing, and it produces less waste than other techniques, such as starting with a base material that is cut away to make the thing.
3D printers also benefit from being computer-controlled machines, also known as computerized numerical control (CNC) machines, meaning they do what they do with minimal human interaction after the design work is done. They can make many identical copies of a thing one right after the other, and the design can be shared online so that others can make their own copies.
