3D printing to order is a regular subject on TreeHugger; we love the idea of making things when you need them, where you need them. And soon you will be able to order up body parts, at a sort of Ponoko for pancreas. Now people sit on waiting lists, hooked up to expensive equipment while they wait for donors and fly body parts all over the world; soon you will order them up fresh and hot. Perhaps, like Philip K. Dick did, we might even call them artif-orgs.
