Abstract: A manufacturing method uses layered slabs to create a final pattern for a mold or for creating the mold itself. The method includes: preparing a desired number of slabs including a first slab and a second slab; machining the first slab; machining the second slab; and after the second slab is coupled to the first slab, repeating the machining step for each additional slab included in the desired number of slabs to form the final pattern or mold.

Abstract: A dispensing nozzle is disclosed herein. The dispensing nozzle includes a hollow enclosure defining an inner chamber. A fluid dispersion element is arranged within the inner chamber and includes a fluid inlet having at least two orifices that respectively open into and communicate with an associated fluid dispersion channel. Each fluid dispersion channel has a reduced cross section from that of the fluid inlet and are arranged to disperse flow of materials received at the fluid inlet into parallel streams of flow prior to recombination of the materials at the nozzle outlet.
