Fabrication of Conductive Patterns by Selective Laser Sintering of Silver Nanoparticles-Photopolymer Ink [PDF]
Recent developments in additive manufacturing (AM) process have led us to fabricate many mechanical and electrical components or devices into complex geometries. Within existing AM processes, laser is widely used as an energy source to selectively sinter

Surface topology modification of organic substrates using material jetting technologies
The ability to directly modify the topology of a surface with three-dimensional micron-scale features provides both a mechanism of controlling how it interacts with the surrounding environment and the potential to impart functional features. Using direct

Nonlinear optical properties of photoresists for projection lithography [PDF]
Optical beams are self-focused and self-trapped upon initiating crosslinking in photoresists. This nonlinear optical phenomenon is apparent only for low average optical intensities and produces index of refraction changes as large as 0.04.
