fast cheap industrial atomic 3d printer

a material is made into a surface 

that functions as a base 

a sheet of matter one atom thick, composed of various atoms 

is held above or on the base surface 

multiple lasers move some of the atoms from the sheet to the base 

then the sheet is moved slightly and the process is repeated 

until the sheet is depleted and a new sheet is required 

the result is that atoms are placed in a pattern as a layer on the base 

and a new layer of atoms are placed in a pattern as a layer 

on top of the previous layer 

and the process is repeated 

so that a product is 3d printed on an atomic scale 

to form a computer chip 

the sheet could be similar to graphene in structure 

but could be composed of carbon atoms, silicon atoms and metal atoms 

or whatever atoms that are appropriate
