3D Printing Blueprints

By: Joe Larson

Overview of this book

A new industrial age is here. Machines designed to build useful and interesting objects have moved from the factory to the home. Whether you have a 3D printer or not, learning how to design your first 3D models is the best way to become part of the 3D printing movement. 3D Printing Blueprints will teach you, step by step, the tools and techniques of using Blender, a free 3D modelling program, to build 3D models for printing with simple and fun hands-on projects.3D Printing Blueprints uses engaging and fun projects that teach Blender modeling for 3D printing through hands-on lessons. First you'll learn basic modeling and make a small simple object. Then each new project brings with it new tools and techniques as well as teaching the rules of 3D printing design. Eventually you'll be building objects designed to repair or replace everyday objects. Finally you'll be able to even tackle other people's models and fix them to be 3D printable. Through the course of doing the blueprints you will custom build one-of-a-kind objects that you can call your own. Starting from a custom vase formed from a picture, lessons will progress to a multi-part modular robot toy. Then simple machines will be designed with custom gears and functions. Eventually you'll learn how to download models from the Internet and make custom objects. Finally you'll be able to build models with near real life specifications and make a print that can be used for small object repair. 3D Printing Blueprints will teach you everything you need to know about building custom 3D models to print successfully on modern home 3D printers.

Modeling the bracelet

It should only take a few minutes to model the bracelet, but don't worry about making it hollow. That will be accomplished with the post-processing. Instead, just make sure the top and bottom are flat for this to work. Perform the following steps for modeling the bracelet:

  1. As usual begin the new project by clearing the scene and saving it in a new directory under MakerbotBlueprints.

  2. Name the new directory Ch 9 Stretchy Bracelet.

  3. Save the project as StretchyBracelet.blend:

  4. Add (Shift + A) a Cylinder to the scene.

  5. Change the options of the cylinder to have 24 Vertices, Depth of 6 to 12, and Radius about as big as the widest point of the hand of the person who will be wearing this, usually around the thumb knuckle. This will be about 25 for a child, 35 for an adult female, and 45 to 60 for an adult male.

  6. Name the cylinder BraceletShape.

  7. Enter the Edit Mode (Tab).

  8. Switch to Face select (Ctrl + Tab).

  9. (De)select (A) all faces.

  10. Select (right-click) on just one of the faces around the...
