3D Printing. No new technology in the last decade has been heralded with as much hope and hyperbole as the promise of desktop replicators fabricating whatever object you need at the push of a button. 3D printing has made huge steps forward, with more sophisticated machines at lower prices, new materials that vastly expand the printer’s capabilities, and the breathless optimism that foresees a printer in every home, as mundane and easy to operate as a conventional printer*.

And yet, for all the hype, most personal 3D printers are pressed into service fabricating plastic tschotskes — low quality, low function items of little to no utility. While the raw potential of 3D printing continues to expand, the promise of personal printers seems mired in the sandbox: an expensive toy for grownups. A toy that produces heaps of plastic detritus that will eventually find it’s way into the environment.

I posit here that, while it is true the the vast majority of people currently have no practical need for a 3D printer, under the right circumstances, a personal 3D printer can be an incredibly useful tool in the modern home.

A little over a year ago, we bought a personal 3D printer. It’s a Printrbot Simple Metal, a tough, no nonsense machine that works as well in my home office as it does at sea. Its footprint is small, and it can handle object up to 150 mm by 150 mm by 150 mm. Not huge, but big enough to be useful. And yes, this printer has primarily been used to fabricate parts for Oceanography for Everyone and other scientific endeavors. You can read more about that here: A 3D-printable, drone and ROV-mountable, water sampler and Oceanography for Everyone: Empowering researchers, educators, and citizen scientists through open-source hardware. I’m not talking about the scientific utility of the printer, but rather, how it fits into our homestead.
