I think the biggest challenge in 3D printing is modelling the object you want to print. I think there would still need to be a huge amount of manual input to help model the object you are trying to photocopy, as just taking a picture of it wouldn’t work. You need to be really good at CAD.
I’ve just seen that you can buy a 3D printing pen (http://the3doodler.com/) which looks very cool!
Well, since 3D printing already exists, certainly. Whether or not they’ll be the sort of thing you can buy in shop and take home is another question. But, given the basic ideas are already there, I’d say that sooner or later we’ll all have one.
