METHOD AND SYSTEM FOR ALL-AQUEOUS PRINTING OF VISCOELASTIC DROPLETS

Abstract: this document describes printing viscoelastic material in an aqueous medium. such printing can involve positioning a print nozzle at specified coordinates in the medium and triggering deposition of the viscoelastic material to form a viscoelastic droplet. the deposition can be established by delivering a specified flow velocity of the viscoelastic material through an aperture in the print nozzle. the print nozzle can be detached from the droplet and a receiving material by translating the nozzle relative to the droplet according to a specified acceleration. the droplet can remain captive on or within the receiving material upon detachment from the nozzle.
