An apparatus for the accurate formation of a free-form three-dimensional article comprises providing a supply of substantially uniform size metal droplets of a desired material wherein each droplet has a positive or negative charge in an enclosed environment. The supply of droplets is focused or aligned into a narrow stream by passing the droplets through or adjacent an alignment mechanism which repels each droplet toward an axis extending through the alignment mechanism. The droplets are deposited in a predetermined pattern at a predetermined rate onto a target to form the three-dimensional article without the use of a mold of the shape of the three-dimensional article. |
