A Beginner's Guide to 3D Modeling

INTRODUCTION

3D printing technologies have revolutionized the engineering world. Just a decade or two ago, designers used to spend weeks constructing prototypes that now take only a few hours to complete. Similarly, a company might have easily poured thousands of dollars into a single prototype part, only to find that it didn’t work properly.

Today, engineering teams produce and test parts at a trivial cost. You likely purchased a 3D printer for these reasons. Whether you’re a maker, a hacker, an artist, or simply a tinkerer, you wanted the freedom to create your own physical objects.

But while operating a 3D printer is easy, the process of actually ...
