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.

Chapter 5. Modular Robot Toy

3D printers can make a number of useful and practical things. But what's the point if you can't have fun too? This blueprint is for a 3D printed poseable robot in multiple parts that connects together with 3D printed connectors. It will be connected with two types of connectors, a pin connector that will do the majority of the joints, and a ball and socket connector for the head.

Before this project begins a lot of planning has to be done. Often projects list this start long before the modeling program opens up. This should be considered normal for any design project. Fortunately in this case the planning is already done and the modeling can begin.

The straight pin connector used here is loosely based on a connector created by Tony Buser on Thingiverse; modified to fit this project. This connector relies on the flexible nature of the plastic to get the head into a smaller hole, until it is past the opening, and can spring back to hold the part in place. When designing...
