The present invention relates to architected stamps having beneficial printing properties. In particular, negative Poisson ratio structures and/or porous reservoirs can be employed to control fluid dynamics and to provide metered ink transfer.
An aerosol jet printhead comprising an in-line static mixer can mix multiple aerosol streams for co-deposition from a single nozzle. A printhead was designed, fabricated, and tested, demonstrating in-plane functionally graded films. The inline mixing printhead can be used with a compact aerosol jet deposition system.

Advances in printed electronics are predicated on the integration of sophisticated printing technologies with functional materials. Although scalable manufacturing methods, such as letterpress and flexographic printing, have significant history in graphic arts printing, functional applications require sophisticated control and understanding of nanoscale transfer of fluid inks. In this paper, a versatile platform is introduced to study and engineer printing forms, exploiting a microscale additive manufacturing process to design micro-architected materials with controllable porosity and deformation. Building on this technology, controlled ink transfer for submicron functional films is demonstrated. The design freedom and high-resolution 3D control afforded by this method provide a rich framework for studying mechanics of fluid transfer for advanced manufacturing processes.
