“The class which has the means of material production at its disposal, has control at the same time over the means of mental production, so that thereby, generally speaking, the ideas of those who lack the means of mental production are subject to it.” – Karl Marx
Now don’t get me wrong, I’m not a Marxist, I just love the confused look that I get from my more “progressive” friends when I quote a little Marx at ’em, as they know I tend toward the libertarian perspective, but at least when it comes to the means of production, perhaps we can find some common ground. To wit, 3D Printing!
I admit, my concept of 3D printing was pretty hazy up until about a year ago, when a friend introduced me. I had imagined it to be strictly the province of movies and high tech prototyping labs and industry. I was wrong. At the consumer level, the price and quality of 3D printers has evolved to a level where even a cheapskate Luddite like me can afford a printer and, just as important, is capable of harnessing and possessing the means of production for less than $300 ready to go. This article is meant to give you the same introduction I benefited from, and the background and resources to investigate further whether this capability is something you can benefit from (of course it is!)
Production of what you may ask? Darn near anything you can imagine! During these days of pandemic and the associated disruption to supply chains, the ability to get desperately needed items from factories across the country and across the world has been demonstrated as fragile indeed. Hospitals and companies have turned to 3D printers to produce their needed components for ventilator circuit connectors, lab testing materials, PPE, and more.
On the individual level, I have for example printed sheaves for an old pulley system that would have cost $50-60 dollars to have bought from a scrap dealer online and shipped to me, when perhaps 25 cents worth of filament and an hour or so on the printer gave me a functional replacement sheave and several spares as well. In order to build an enclosure for the netting my wife puts around the strawberries to keep birds out, I printed a series of connector brackets that hold half-inch conduit piping together at the joints. To demonstrate ratios of mass to surface area my kid’s printed gliders they can launch with rubber bands and measure their flight times. Do you need a bracket of particular size and shape to hold something in an odd spot, temporarily or permanently? Print the bracket to your own spec!
Back during the face mask shortage this spring, I was able to print face masks that could be screwed in series to allow various levels of filtration. I had long ago lost the drain plug for an old Igloo brand cooler…I had been sticking cotton balls wrapped in plastic cling wrap into the drain hole to try and prevent leakage and delay melting, but it was always a poor substitute. 10 cents of plastic and an hour on the printer, and I have a drain plug that works as well as brand new. Battery boxes, socket wrench organizers, hose thread adapters, and one of my wife’s favorites, a coupler that allows us to refill small, travel-sized toothpaste tubes from larger (more economical) toothpaste tubes. These are but the barest fraction of useful objects you can produce in your home…but the real excitement is yet to come.
Perhaps global supply chains stay disrupted…or maybe they don’t…could some equal or worse disruption ever occur again? Readers of this blog already know and are preparing for the possible ramifications of such events. But perhaps it isn’t supply chains that cause a future shortage of needful things…perhaps it is legislation. You see, beyond garden brackets and toothpaste couplers, there is much more that can be produced, and that much more includes things like 33-round Glock 9mm magazines. It includes things like pistol stabilizing braces. It even includes things like lower receivers for AR-pattern rifles and Glock or Smith & Wesson-type pistols. And much, much more.Continue reading“3D-Printed Freedom – Part 1, by A.M.”
