Overview of this book

Blender is an open-source modeling and animation program popular in the 3D printing community. 3D printing brings along different considerations than animation and virtual reality. This book walks you through four projects to learn using Blender for 3D Printing, giving you information that you need to know to create high-quality 3D printed objects. The book starts with two jewelry projects-- a pendant of a silhouette and a bracelet with custom text. We then explore architectural modeling as you learn to makes a figurine from photos of a home. The final project, a human hand, illustrates how Blender can be used for organic models and how colors can be added to the design. You will learn modeling for 3D printing with the help of these projects. Whether you plan to print at-home or use a service bureau, you’ll start by understanding design requirements. The book begins with simple projects to get you started with 3D modeling basics and the tools available in Blender. As the book progresses, you’ll get exposed to more robust mesh modeling techniques, modifiers, and Blender shortcuts. By the time you reach your final project, you’ll be ready for organic modeling and learning how to add colors. In the final section, you’ll learn how to check for and correct common modeling issues to ensure the 3D printer can make your idea a reality!

Using Object Origins to line up objects

Now that we have both a cube and a cylinder in our project, we want to move the cylinder so it rounds out our cube perfectly. To do that, it is helpful to understand the Object Origin and how Blender uses it to interact with your shapes.

Understanding Object Origin points

Whenever you select something in Object Mode, a yellow dot indicates what is known as the Object Origin:

Examples of Object Origins.

By default, the Object Origin is the key point when Blender is manipulating and interacting with your selection:

  • Scaling: When you scale an object, it scales outward from that Object Origin. If your origin is in the center, the object will grow equally on both sides. If your origin is...
