Any liquid material is a candidate for MicroPenning®. Generally, applications call for flowable materials that range in viscosity from 5 to 500,000 centipoise (cP). A wide variety of Micropennable inks have been identified or developed and optimized for both low temperature flexible polymeric substrates, as well as high-temperature ceramic substrates.
