Abstract

A system and method for computer controlled flexible manufacturing of aluminum articles having patterns thereon is disclosed. The pattern is digitized or otherwise reduced to computer-readable format and then printed onto an aluminum article under computer control. The pattern is preferably printed using an ink jet, dot matrix color printer which has been modified to feed the aluminum substrate in an essentially flat manner. The pattern can be sealed within the anodized coating of the aluminum article for permanence.

Claims

1. A computer automated flexible manufacturing system, comprising:

visualization means for creating a computerized design specification of an aluminum article of manufacture, the computerized design information including a specification of a material for the aluminum medium, size information for the aluminum article of manufacture, packaging instructions and shipping information for the aluminum article of manufacture upon completion; and

a manufacturing computer, remote from the visualization means, connected to the visualization means to receive the computerized design specification; and

a printing unit operating under control of the manufacturing computer, the printing unit receiving an aluminum medium and printing a pattern on the aluminum medium as specified by the computerized design specification to produce the aluminum article of manufacture, wherein the manufacturing computer orders the aluminum medium, controls pre-printing processing of the aluminum medium prior to presentation to the printing unit, controls post-printing processing of the aluminum article and controls shipping of the article of manufacture.

2. A system as recited in claim 1, wherein the pre-printing processing includes anodizing the aluminum medium and the post-printing includes cutting and sealing the aluminum medium.
