Abstract
A method of producing a pattern shaped article includes the steps of forming at least two different courses of dry particles overlaid 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 effect an air flow to form a cavity corresponding to a pattern expression in at least a lower dry particle course 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 of a different type of dry particles into the cavity and allowing the particles to set into an integral mass.
