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.

Posing the bear

This bear is a great looking model, but it's not printable the way it is. Keeping in mind the overhang and bridging rules from Chapter 1, Design Tools and Basics, the bear needs to be put in a pose that will print. The legs are a clear problem so the bear will be made to sit on a box.

Use the combo box at the bottom of the 3D View panel to switch from BearSkin to Object Mode.

  1. Add (Shift + A) a cube to the scene.

  2. Scale (S) and position (G) it so it is under the bear's hips.

  3. Select (right-click) the hip bone in the armature.

  4. Rotate (R) the hip bone around the x axis (X) to make the bear sit.

  5. Select (right-click) the calf bone.

  6. Rotate it (R) around the x axis (X) to bend the knee.

  7. Repeat with the other leg.

  8. Select (right-click) and Rotate (R) the cube around the z axis (Z).

  9. Position (G) the cube in the xy plane (Shift + Z) to put it properly under the bear.

  10. Select (right-click) the bone through the body.

  11. Rotate (R) it slightly around the x axis (X) to get the bear to lean back a little...
