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.

Just like being able to modify the settings on a 2D printer allows for things like double-sided prints or printing multiple pages on the same sheet, manipulating slicer settings has advantages as well. In this chapter, a simple model was modified, not by modeling but by changing the print settings to turn a modified cylinder into a bracelet. Alternatively, turning the top and bottom fill layers off, but turning the infill on is an interesting way to make a perfect screen with a controlled mesh.

Some slicers used for other 3D printers don't allow access to settings such as the slicers for Makerbot but most RepRap based printers do. In that case, it would become necessary to remove the top and bottom faces and modify the bracelet to just be a minimally thick wall in Blender. The problem with this is that many slicers, even professional level ones, have a bug that shows up with walls that are of the wrong thickness. A gap appears in the middle of the wall, where the slicer wants to put...
