Hence why makerspaces are becoming popular, and why I am working on self-expanding production (where you make parts for more machines to expand your capabilities). A home 3D printer simply won't satisfy most needs that people have. A makerspace (community workshop) can afford to have multiple computer-controlled machines (CNC Router, laser, etc.) that can work in different materials and different sizes. For example, a 4x8 foot router table can cut up an entire sheet of plywood to make self-assembled furniture. Such a device is reasonable for a community shop, but unreasonable for most home users.
The next step will be a "MakerNet". A single community workshop may not have all the machines to make a desired product. So when you want something, software will divide up the product design files and send them out to multiple locations, who between them can do all the various parts.
