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.

Fixing the armature weights

Sculpting the model added geometry. Decimate took some away. Even if the weights attached to the armature were correct to start with it's very unlikely that they would still be. In order to make the armature useful again the weights need to be repainted.

  1. Switch the BearSkin to Weight Paint mode (Ctrl + Tab).

  2. In the Outliner panel unhide the Armature.

  3. Select the Armature in the Outliner panel and insure that it is in Pose Mode.

  4. Insure that the Pose Position button is selected in the armature object data tab.

With the BearSkin in Weight Paint mode and the Armature in Pose mode/Pose Position, it is time to fix the weights.

Similar to sculpt mode, the weight paint mode has a set of brush tools, but really there is only one brush necessary. The draw brush has a blend option that duplicates all the other brushes and is considerably easier to find the tool desired.

  1. Select (right-click) the BearSkin.

  2. Verify the Weight and Strength are 1.

The procedure is as follows:

  1. Select a bone...
