We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I first saw 3D manufacturing/printing exhibited in 2002 or so - the guy pitching it was telling how it could be used in space on the shuttle to make replacement items. That's an awfully small market, and the products (he admitted) had a short lifespan.
Looks like it has moved much further along now. Oddly enough, I had a conversation just last week about 3D printing at a trade conference I was attending.
The discussion had started because my car had broken down (yet again) and was in the shop. The fellow I was speaking with asked if my shop had a 3D printer, which could produce quality goods cheaply and rather quickly...and in color(s).
If any garage has one, I'd be surprised. I think they must be expensive.
