Method for production of patterned shaped articles
First Claim
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.

Abstract
An apparatus for simultaneously supplying at least two kinds of particles onto a given surface, includes a movable supply head having at least one partition member for partitioning the at least two kinds of particles and defining at least two supply ports in conjunction with the supply head; and a device for introducing the at least two kinds of particles into the supply head. A patterned shaped article is produced by a method using the apparatus. The method includes simultaneously supplying the two supply ports of the supply head, with the one partition member abutting on the given surface, thereby forming a pattern course on the given surface, and allowing the pattern course to set into an integral mass.
