rough calculations, but an iPhone 5 screen's area is 4656mm. this process makes 1mm/hour. So, does that mean it'd take ~191 days to make 1 screen? have i missed something major?
I think the 1mm/hour refers to accretion depth-wise across the entire existing diamond surface area. So conceivably (but probably subject to other factors that would complicate matters) if you started with a .001 mm thick diamond slice with 4656 mm^2 surface area and applied this process on one side then it would take 3 hours to get a 3mm-thick diamond slice.
okay, that makes more sense. thanks for the explanation!
