Abstract
A method of producing a 3-dimensional (“3-D”) product from metals in the gaseous state includes the steps of providing a substrate of 3-D shape; providing a flow of a gaseous chemical compound(s) around the 3-D substrate, wherein the gaseous chemical compound(s) comprises a metal carbonyl gas; selectively heating the 3-D substrate to decompose the metal carbonyl gasses, wherein metal separated as a result of the decomposition is deposited on the 3-D substrate; selectively controlling the flow rate of one or more metal carbonyl gasses and the temporal and spatial temperature distribution throughout the 3-D substrate to achieve a desired thickness distribution of the metal or metals on the 3-D substrate; and removing the 3-D substrate to produce a resulting 3-D metal product with an complex geometry.
