Appendix A: 3D Printing and OpenSCAD

This book assumes that you know a little about 3D printing already. However, if you do not, this Appendix will get you started and give you resources to figure things out from here.

The 3D-Printing Process

First, we should say that you do not just “hit print.” The amount of expertise and knowledge required is probably more analogous to cooking, or perhaps to using a sewing machine. 3D printing is rapidly evolving, too, so the details of what we say here may change, although we expect the basic ideas to stay the same for a while.

Having said all that, 3D printing requires three steps. Figure A-1 shows you the overall workflow for creating something with a 3D printer. This appendix concentrates on two free progams ...
