Automated 3D Printing

MakerBot has designed, built and offered for sale a heated build platform for their MakerBot (which means it should work on other 3D platforms like Mendel, Darwin, et. al.) which removes finished product from the build area, making it possible for a 3D printer to run complete many items unattended.  This ought to spread the availability of RepRap much more quickly than expected.  In twenty years or less every home handyman will have one, or its descendant.
