Fabrication of Three Dimensional Structures By In-Flight Curing of Aerosols

摘要

A method for fabricating three-dimensional structures. In-flight heating or UV illumination modifies the properties of aerosol droplets as they are jetted onto a target surface. The UV light at least partially cures photopolymer droplets, or alternatively causes droplets of solvent-based nanoparticle dispersions to rapidly dry in-flight, and the resulting increased viscosity of the aerosol droplets facilitates the formation of free standing three-dimensional structures. This 3D fabrication can be performed using a wide variety of photopolymer, nanoparticle dispersion, and composite materials. The resulting 3D shapes can be free standing, fabricated without supports, and can attain arbitrary shapes by manipulating the print nozzle relative to the target substrate.

1. A method for fabricating a three-dimensional structure on a substrate, the method comprising:
propelling aerosol droplets from a deposition head toward the substrate; partially modifying a property of the aerosol droplets in-flight; and fully modifying the property of the aerosol droplets once they have been deposited as part of the three-dimensional structure.
