From Science Daily's article, here's what some people are doing:
"Biologists at Rockefeller University have been using a Fab@Home to deposit slime mold cells in various arrangements to see how the distribution influences their ability to form colony organisms.
The British magazine Auto Express suggests that fabbers could be used to make auto parts, allowing individuals to customize cars in ways that were previously available only to those with large manufacturing facilities.
While the usual expectation is to make solid objects out of epoxy or other quick-hardening plastic, the Fab@Home also can be used with plaster, Play-Doh, silicone, wax (to make forms for casting), low-melting-point metals and a variety of other materials.
