Having been buying quite a lot of toys for our young children recently, it did sort of strike me that a moderately affordable 3D printer that really did Just Work, where I could go to, say, lego.com, click what I wanted a model printing of, and then it all just happened, as if by magic... would be something I'd buy. I think the combination of convenience and "Wow, that's cool" would be quite compelling, even if it didn't really work out all that much cheaper. On the whole, though, I'm really struggling to see how these things will ever take off. (Like others, I have a paper printer which I use a handful of times a year, and it's never an experience I relish. At least printers are very cheap now, even if ink isn't.)
