Yeah, but the printers will eventually sell for $9.99.
If I want to print out a document, I go to the library with my USB port and pay 15 cents a page.
I have been using 3D printing in my business for 3 years now.
We can create complex shapes in a CAD program out of a nylon type plastic that a customer buys from the printer and we get back a small fee for the design work. We never see or touch the part.
Fantastic results. The company we use is shapeways.
Waiting for the price of 3d scanners to come down. And they are starting to.
