What will this 3D printing revolution look like? Who will be affected? Who won't be affected? Will it save resources or use more? What are it's limits? I want a replicator in my house so I can download a torrent of my favourite carbon bicycles, parts and new motorcycle. Maybe I can 3D print myself a new house. Why not? Who even needs nanotech if you have 3D printing? How do you see 3D printing affecting your life or society?
