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.

Flattening the bottom

The bottom of the mug, while flatter than before, is not perfectly flat and is therefore not suitable for printing yet. However, there is a way to use the scale operator in Edit Mode to make a flat bottom, by carrying out the following steps:

  1. Jump to the front view (Numpad 1).

  2. Enter Edit mode (Tab).

  3. Clear the selection (A).

  4. Use the Box Select operation (B) to select the bottom few layers.

Without touching the mouse carry out the following steps:

  1. Begin the Scale (S) operation.

  2. Press Z to lock the scale operation to the z-axis.

  3. Type 0 (zero) to scale by a factor of zero.

  4. Press Enter to end the scale operation.

Rotate the view and notice that all the points that were there before are still there, they are all just on the exact same z level making a perfectly flat bottom for printing.

Remember to save (Ctrl + S).
