UV curable inks were formulated for our multi-material inkjet 3D printer. The  properties and inkjet behavior of liquids were characterized and optimized. They are fast curing along with good surface curing ability. With our current materials library, 3D objects with full colors and gradient mechanical or optical properties could be printed out. Besides the UV curable materials, solution based inks such as metal particles dispersion are being explored with our 3D printer also; With the development of all kinds of functional printable materials, 3D printing is quickly expanding the applications in sensors, actuators, PCB, etc.
