ABSTRACT:
A method for producing an article having a body with one or more enclosed channels extending therethrough such as for the circulation of fluids. The body is formed preferably by metal deposition about one or more fibers to generate the enclosed channels with at least one end of the fibers extending beyond the body. The fibers are then extracted from the channels in the body to leave open the channels through which fluid may be circulated.
