3D Printing with SketchUp - Second Edition

By: Aaron Dietzen Aka 'the Sketchup Guy'

Overview of this book

Working with the amazing 3D printing technology and getting access to the printing hardware is now easier than ever before. While there are many other resources that cover the general process of 3D printing, this book is the ultimate guide to creating models for 3D printing using SketchUp. You’ll start with a basic understanding of how SketchUp is used in the 3D printing workflow and jump into the steps to create a print-ready model using only SketchUp. This 3D printing book will guide you in using SketchUp to modify existing 3D files and cover additional tools that make SketchUp an even more powerful modeling tool. As you advance, you’ll learn how to transform 2D images into 3D printable solids, how to create multi-part prints that can be assembled without the use of fasteners or glue, and how to make sure your model, whether designed from scratch or assembled from preexisting geometry, is ready to be made real via your 3D printer. By the end of this book, you’ll have the confidence to bring your design ideas to life by generating your own 3D print-ready models with SketchUp.

Considering wall thickness and support

I do have to admit that slicing software has come a long way in the past few years. I remember when I started 3D printing, the software I was using was barely able to do much more than generate support for overhanging geometry. Nowadays, it can repair meshes, automatically orient models, and, in some cases, it can even print non-manifold geometry.

While I am all for taking advantage of this software when it makes sense, there are some things that you may want to control yourself, as you create your model, such as creating your model with proper wall thickness and creating geometry that will reduce the need for support.

Modeling wall thickness

Let me start by describing exactly what I am talking about here. I am using the word wall in reference to any geometry that creates the outside geometry of your model. To be properly manifold and printable, walls must have some thickness. They cannot exist as simple faces. Take the example in Figure...
