3-D Printing
I agree with most of what you wrote. 3-D printing is in its infancy and there are limited things that can be printed as objects at this time. It will take more time to improve the process and make it both quicker and also use a wider variety of materials.
What is driving 3-D printing is the ability to make quick prototypes and the do it yourself movement. This is where the idea of a neighborhood 3-D printing comes into play; a business called The Tech Shop is a place where people can learn to use 3-D printers and other equipment that is available for members to use for their projects. This model supports a range of expertise from the hobbyist to those who are developing products. The equipment ranges from table saws and shapers to laser cutters and 3-D printers. There are other places similar to the Tech Shop that cater to the public.
