A direct-write method for depositing a polarized material of a predetermined computer-aided pattern onto a target surface, the method including the following steps: (1) forming a solution of a material capable of being polarized using a polarization solvent which can be removed by evaporation to provide a polarized material; (2) operating dispensing devices to dispense and deposit the solution onto the target surface substantially point by point and at least partially removing the solvent from the deposited solution to form a thin layer of substantially solidified material of the predetermined pattern; and (3) during the solvent-removing step, operating a high DC voltage for poling the deposited solution to achieve polarization in the material. The invention also provides a freeform fabrication method for building a multi-layer device, such as a micro-electro-mechanical system (MEMS), that exhibits piezoelectric or pyroelectric properties.
