When will we have urine powered, desktop 3D printers?
Ok, That may not have actually been one of the questions, but I did mention urine, desktop 3D printers and Shapeways in a recent interview on ABC radio in Australia. You can download the interview or listen here.
Thanks to Alan Brough for the engaging conversation and Kulja Coulston for making it happen.

A good interview, it illuminated problems and issues very well for the casual listener, r.g., myself :o)
Thanks Peter, I am glad it helped.
