Blender 3D Printing Essentials

Overview of this book

Like computing, 3D printing has been around for decades but it was expensive and was only used for making complex prototypes. Now, prices have dropped and third-party printing services such as Shapeways have become available, making the technology available to everyone.Blender is an open source modeling and animation program popular in the 3D printing community. 3D printing demands more of a modeler than animation or virtual reality. The model maker must engineer their model to work in the real world. They must keep in mind the particular needs of the materials and printers that they are planning to use to print their model. This practical guide gives Blender users all the information they need to design high-quality 3D printed objects. With a solid exploration of the 3D modeling process, design considerations for 3D printing, plus step-by-step exercises, you will soon be comfortable making 3D objects for real-world enjoyment. Starting with an overview of 3D printing, this guide moves onto to precision measurement, fixing problems in a 3D model, and how to make it light and strong enough for real-world use.You will learn how to scale, build, and detail a model for a 3D printer. You will learn to color and decorate it, as well as making parts precisely in the size you want them, so that multi-part objects fit together smoothly. You will also learn tips on saving money when you have printed your model.With the help of this guide, you will be able to complete your project and learn how to export the file so it is ready for a variety of 3D printers.

Preface

You know that 3D printing is hot. You wouldn't have bought this book if you didn't. What I hope you will get from this book is an introduction to building a model in Blender so it will make a good object in a 3D printer.

This is fairly simple. Mostly, you need to know what information the 3D printer needs to make an object, what considerations you need to make when designing your object, and which techniques you can use to achieve your goals.

I have tried to avoid being printer-specific. 3D printing is in the phase where new printers are appearing every day. At some point, there will be a shakeout where the best printer makers prevail, but it's too early to guess which companies those will be. But among all kinds of printers, there are basic rules that will work with any printer, and you will learn how to tailor your objects for particular printers.

While I have worked to ensure that you could do each step demonstrated, I assume that you have a general knowledge of operating Blender, such as one would get from my book Blender 3D Basics, also available on the Packt website.

Let's get started!

What this book covers

Chapter 1, Designing Objects for 3D Printing, gives you a glimpse into the general issues affecting 3D printing and background on what is going on, so you understand why you may have to do things differently to make an object in Blender for 3D printing than you do for animation or the game engine.

Chapter 2, Measuring and Texturing Techniques for 3D Printing, explains how to prepare a file to be used in 3D printing. We will cover using the Ruler/Protractor tool to measure objects and some methods used in texturing the model.

Chapter 3, Making a Blender Model that's Ready to Print, explains how to make models that are watertight, manifold, and will print well.

Chapter 4, Making Strong, Light Objects with the Solidify Modifier, explains how to make an object strong and light using the Solidify modifier and how to clean up the model. You will also learn about doing precision modeling, dealing with overhangs, and finally you will learn how to export the completed file.

Appendix, contains links to good background material on 3D printing, 3D printing services, hobbyist-level 3D printers, industrial-level 3D printers, and Blender objects available on the web.

What you need for this book

Blender 2.67 or higher and a general understanding of standard modeling techniques, such as described in Blender 3D Basics.

Who this book is for

People who want to be able to build 3D printed objects using Blender to model the object(s).

Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Set the radius of the brush to about 25 and the strength to 1.0".

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In the UV/Image Editor header, select Image".
