The logical steps in 3D printing is to increase the number of molecules the printer can print with. There's almost an infinite number of molecules you have to deal with, so it's a very logical step that once 3D printing becomes a commercial endeavour then there'll be quick steps made towards an atomic printer.
91 regularly occurring natural elements is a much shorter order than tens of thousands of common molecules. Considering there are over forty simple hydrocarbons and molecular printers start looking bulky, granted you might only ever use a maximum of 5 hydrocarbons, but that day you need a 6th you'll be cursing your shitty base model printer.
