1. An architected stamp having a proximal end and a distal end, comprising:
a porous reservoir comprising a plurality of first pores and a contact surface disposed at a distal portion of the porous reservoir, wherein the plurality of first pores is in fluidic communication with the contact surface; and
an ink transfer component comprising a plurality of printing elements, wherein each of the plurality of printing elements includes one or more compressible structures in fluidic communication with the contact surface at a proximal portion of the ink transfer component and which can be mechanically deformed to deliver ink to a substrate at a distal portion of the ink transfer component and wherein the proximal portion of the ink transfer component is separated from distal portion of the porous reservoir by the contact surface.
