Thanks Rob!
Thank you Johann, the pump was created in Solidworks and printed by a now defunct division of Finelines Prototyping (Print A Part). I think a company called Shapeways is still doing Invision machine printing with thier "Frosted Ultra Detail" material.
I have an album with more info here:

Thanks Skip, the whole 3D scanning thing is just as amazing as the printing. It reduces or eliminates the need to create models on the computer, and the scanner sizes are getting larger all the time.
