A method of producing a pattern shaped article includes the steps of forming at least two different courses (12, 13) of dry particles overlaid on a base surface (10); using an air flow controller (20) having either a suction port (21) or a blow port (28) or both a suction port and a blow port to effect an air flow to form a cavity corresponding to a pattern expression in at least a lower dry particle course (12) by removing a portion of the lower dry particle course under 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; collapsing particles of an upper dry particle course (13) of a different type of dry particles into the cavity and allowing the particles to set into an integral mass. <IMAGE> |
