1. A method for producing a patterned shaped article, comprising the steps of:

  • disposing a layer of particles on a given surface;

    providing on the layer of particles a head having at least one supply port and at least one suction port;

    moving the head to trace a pattern to be formed while simultaneously removing a portion of the particles of the layer by suction using the at least one suction port to thereby form a cavity of a clear-cut pattern in the layer of particles on the given surface;

    supplying into the cavity of the clear-cut pattern particles different from the removed particles such that the supplied particles can cooperate with the particles of the layer to maintain the clear-cut pattern, the supplied particles being supplied from the at least one supply port, thereby forming the layer into a resultant layer of particles having the clear-cut pattern on the layer, at least some of the particles of the resultant layer being settable particles; and

    allowing the resultant layer of particles to set on the layer.
