The 3D printing phenomenon

3D printing is the hot new thing. I have not used one myself but a colleague of mine says that the cost of such things is dropping rapidly (you can now get one for less than $1000) and he has several in his lab because the cost of repairing the older, more expensive ones is now often greater than the cost of buying a newer and better one. He says that they come in extremely useful for creating customized items for his research.

This video explains how 3D printing works, what it can do, what issues are involved, and where it is going.
