I wish I could figure out how to invest for 3D printing. The printers will print themselves, the raw materials are just commodities. The only thing I can think of is a company that will license the designs to be printed.

I know what you mean. It's like being on the verge of another PC revolution (and all that opportunity). I don't know how to take advantage of it though, other than benefit from it by being a user when it's ready for prime time.

Another decentralizing technology could be in electric power generation. "60 Minutes" had a story a while back on the Bloom box -- it generates electricity from natural gas. They're projecting getting it practical for an individual house.

Yes I'm sure there's a Steve Jobs or Bill Gates in a garage somewhere cooking up plans to put a manufacturing plant in every home. I wonder if there's going to be a new market for raw material supplies e.g. for those used in Laser Sintering.
