3D printing (also known as additive manufacturing) is a perfect example of what Mises Fellow & University of Oklahoma professor of economics, Per Bylund, describes as vertical counter economics. In this article he defines the vertical strategy as the creation of local production facilities which fall outside the state's purview.
In this episode of The Agora, we cover some of the various use cases for 3D printing counter-economically. From bump stocks to kidneys, 3D printing offers the agorist a myriad of regulations to nullify. I also discuss my own experience getting started with 3D printing as a hobby. If you're interested in learning more, I wrote 3D Printing For Libertarians: A Beginner's Guide back in September. It's a good primer to the more technical aspects and gives you the info you need to get started.
