Question 1: How will the partially assembled bearing be held in a fixed position in order to add atoms to it? Would a "velcro floor" of atoms that form less powerful bonds be used while assembly is taking place?
Question 2: Is there a reason why a "printer approach" would not be ideal? I'm thinking of a nanoscale version of the modified inkjets that are being tested for synthetic organ construction. Aren't those adding a layer to a 3 dimensional object? Isn't this (admittedly at smaller scale w/ greater accuracy) what nanotech is looking to do?
Please share your views on these AND/OR whether this seems the appropriate forum for these newbie questions.
