Mendel and other open source 3D printers
I'm currently tuning a Prusa Mendel, and will upload some examples, links, information, and hints soon!

The lasercamm cuts 2d parts out of many non-reflective materials. These parts can be used to build up 3d shapes. The precision of 2D rapid prototyping lends itself well to templates for routing, drilling, or circuit printing. A laser method of cutting lets one make inside cuts very easily. For example, the autonomous robot below was designed in CAD, and produced (at least the parts for it) with a LaserCAMM from a sheet or two of acrylic.
Additionally, the contest table for which this robot was designed was produced on a LaserCAMM after being designed in CAD.
otherwise nothing of note yet...but keep checking...
