# How do molecular 3D printers create macro scale structures? [[Molecular 3D printers need a way to arrange hierarchically]] If we think of molecular 3D printers as 2D or 3D [[Artificial ribosome]]s, it pops up to the question of [[How does biology create macroscale structures?]] This is one of the big challenge of [[Artificial ribosome]]s <!-- #questions --> [Web URL for this note](http://notes.benjaminreinhardt.com/How+do+molecular+3D+printers+create+macro+scale+structures) [Comment on this note](http://via.hypothes.is/http://notes.benjaminreinhardt.com/How+do+molecular+3D+printers+create+macro+scale+structures) <!-- {BearID:83863FE5-3EA0-4FFE-BA81-48AC5121D20D-9440-0000E006E71809C0} -->
