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.

Trimming the fat

After the file is saved, open Blender, clear the scene, and save the scene in Documents\MakerbotBlueprints\Ch 8 Scan Repair and name the file Lion Cleanup.blend:

Import the file to be cleaned up by clicking on the menu options File | Import | Wavefront (.obj):

Double-click on the CH8_LionCapture.obj file. The file is very large and may take even a high-end machine a few seconds to process. When imported, it may be difficult to find the subject of the scan in all the extra data. The subject will be near the middle. Zoom in and adjust the view until the lion in the middle is framed in the view.

When zoomed in, it becomes clear that the lion is at a strange angle to the work plane.

3D scans often capture more than the focus of the scan. All that extra, loose geometry needs to be separated and eliminated, which will make the model much easier to manage. To do this the Separate command will be used:

  1. Select (right-click) the scanned object.

  2. Press Tab to enter Edit Mode.

  3. In the menu at...
