This article describes an ink‐jet printer for the construction of combinatorial libraries and functionally graded ceramics. It can mix and print all possible compositions for high‐throughput screening. The number of components is set by the number of mixing valves that deliver ceramic ink from pressurized reservoirs into a circulation chamber. Compositional control is by either complete or incremental change. Organic liquids and ceramic inks are used in a systematic three‐stage calibration. The calibration protocol accounts for the effects of ink viscosity, reservoir pressure, valve‐opening time, and temperature, but reveals unexpected segregation effects that occur in the ink after deposition.
