- 54 - ABSTRACT OF THE DISCLOSURE A method of producing a patterned shaped article includes the steps of forming a course of dry particles on a base surface; using an air flow controller having either a suction port or a blow port or both a suction port and a blow port to cause an air flow to form a cavity in the dry particle course by removing a part of the particles thereof under the control of at least one parameter among air pressure, air flow rate, air flow speed, air flow direction, air flow pulsation, air flow intermittence, suction port size, blow port size, suction port position and blow port position; charging the cavity with a different type of dry particles; and allowing the particles to set into an integral mass.
