Summary form only given. We use optical forces to guide aerosol particles through hollow-core optical fibers. A wide variety of materials can be manipulated including solid metal, dielectric, and semiconductor particles as well as liquid droplets. The guided particles emerge from the fiber in a narrow beam and can be deposited on a substrate placed near the fiber output tip. By translating the substrate during particle deposition arbitrary structures of lines and dots can be constructed. The deposition conforms to the substrate curvature and the structures can be defined with micron resolution. The laser beam is intense enough to melt many types of particles during delivery to the substrate. The resulting structures are fully dense and well adhered.
