Abstract

A method of making a bonded polymeric assembly by transfer printing comprises contacting a stamp with a solid-phase ink comprising a photoresist to form an inked stamp, where the solid-phase ink is reversibly bound to the stamp. The inked stamp is aligned with an object comprising the photoresist and is stamped onto the object. The stamp is then removed, thereby transferring the solid-phase ink onto the object. The solid-phase ink is thermally joined with the object. Thus, a bonded polymeric assembly comprising a bonded joint between the solid-phase ink and the object is formed.
