3d Printers

Ok, so I read the Huffington Post article on 3d scanners and I must say, THIS is really cool!
In terms of what I didn't know before reading the article, I didn't know that:

• There were such things as 3d printers! I had no idea that they existed. I was TOTALLY unaware.
• They are so popular among customers and that by 2007, over 80,000 3d printers had been sold! That's unbelievable!
• These 3d printers were capable of copying such robust things, such as keychains and game board pieces. That sure is handy!

In my opinion, this article is great. I find it so intriguing that there are printers that can copy 3d objects. If I had one of those printers, I'd never run out of sketchbooks! :)
I would definitely buy one, although they are somewhat expensive..

I also enjoy the fact that so many people make good use out of these printers! In my opinion, I think that having one of these printers would be worthwhile, especially around the holidays!

I do have one question though.

If you were to copy certain 3d items, would there be copyright issues involved? I'm just curious.
