Our group has been engaged in 3D printing of various materials to create complex architectures for obtaining unique structure-property relations. The materials systems range from polymers, metals, ceramics, cement, graphite and other unconventional structures like wood. The printing techniques range for direct ink printing to filament printing to 2-photon polymerization. The goal is to be able to move towards materials agnostic architectures by creating complex structures that can compensate for materials limitations and sustain failure mechanisms. Creating architectures that can withstand extreme conditions such as ballistic damage is of interest. Improving feature resolution of printed structures to nanometers and increasing compositional complexity are also of interest.
