I’m sharing this mostly because it’s beautiful, but also because this is what a self-reliant future looks like. You’re — we’re — going to be able to print the items we need.

The price of home 3-D printing (also called additive manufacturing) is dropping fast. Advances in the materials that can be used range from polymers, to steel, to Kevlar, to glass, to stem cells.
This is going to be a huge thing for localism and self-reliance. Let’s get aboard the 3-D train now!
