Abstract

Methods of fabricating three-dimensional structures comprise: contacting a printing plate face with a suspension comprising particles to arrange the particles at predefined positions on the printing plate face, the predefined positions comprising a first position laterally adjacent to a second position; positioning the printing plate with the printing plate face turned toward a substrate and the first position aligned to a protrusion on the substrate; contacting the protrusion with a first layer of particles disposed at the first position of the printing plate to transfer the first layer of particles to a protrusion surface; moving the printing plate laterally to align the second position to the protrusion; and contacting the first layer of particles disposed on the protrusion surface with a second layer of particles disposed at the second position of the printing plate to transfer the second layer of particles to on top of the first layer of particles.
