ABSTRACT:
A method of producing a patterned shaped article which includes the steps of placing on a base surface, a form made of at least one partition member defining the boundary of the patterned to be produced, a peripheral frame surrounding the partition member at a prescribed spacing therefrom and a cover closing the upper ends of the partition member and the peripheral frame. The method also includes the steps of supplying dry particles to a pattern space enclosed by the partition member and a pattern space between the partition member and the peripheral frame, removing the form from the base surface forming a particle course having a prescribed pattern and causing the particles to set into an integral mask.
