Abstract: The invention relates to a process for the manufacture of a part penetrated by fluid channels or ducts for the manufacture of a mold that includes channels or ducts for the circulation and/or transfer of a fluid from the molding portion to the non-molding portion and vice versa. The part is formed and manufactured by a Stratoconception (TM) method based on the principle of decomposing the part, via a set of inter-stratum planes, into a succession of strata. After assembly, the part is formed, and channels are provided in the various inter-stratum planes for allowing a fluid to pass through the part. The invention also relates to the parts obtained by the process.
