For those interested in 3D printing (and drafting/sculpting), you might want to see if you have a FabLab in your area.
It's a digital fabrication facility (I think the name came from a British TV show), open to the public, that lets people learn and experiment with digital technology at its intersection with manufacturing or production technologies. We have on here in Bethlehem, for example; it's affiliated with our local community college.
Among other features, it has facilities for 3D drafting and printing. You can take classes through the college, or just sign up to use the facility on your own. I think there's a modest annual subscription that offers full use of the facility, including instruction, but you can just go in and talk free of charge.
Local businesses also provide support and sponsorship to ours. For example, Martin Guitars operates a luthiery, a workshop for making stringed instruments. They send their new employees there as apprentices to work, before integrating them into their workshop. But if you want to make yourself an acoustic guitar, you could sign up and do it there. And see how digital technology is part of the process.
They also have a metal shop and a wood shop, and a sound studio.
The 3D printing facility is sponsored and supported by a local manufacturer of artificial limbs for people who have been injured or who have a congenital deformity. I got to talk to the owner about his product and his own facility. For children who need an artificial limb, especially, the traditional method of fitting and crafting the limb isn't as efficient as using 3D drafting and printing to do it. It's faster and less expensive. And that's how he started out. His own facility fits in a large 3-bay pole barn.
Another sponsor of ours is SmoothOn. They're located here in the Lehigh Valley, and they provide demonstrations and instruction on mold-making and casting.
Here's a link to a list of such facilities in the US. If you live somewhere else, just follow the link and then filter it for your own country.

On a tangential note, our local club lost its meeting place, an AC Moore store, when they went out of business. I looked into holding our meetings at the FabLab. The director was glad to have us, we would have had access to the facility, and we could show off the kinds of things you could do. But the guys voted it down. Still, I keep it as an option for the future, because it's an incredible opportunity for a bunch of scale modelers, to have access to 3D drafting and printing facilities, and mold-making and resin casting, all free of charge.
