Abstract: Described herein is a method of forming a 3D investment mold using a layer-by-layer construction (3D printing). The mold is configured for receipt of a molten alloy having a composition configured to form a bulk metallic glass (BMG) on cooling. The mold has a hollow interior between inner and outer walls. The hollow interior receives the molten alloy for molding it between the inner and outer walls of the mold. A method of casting using the 3D investment mold is also disclosed, which may include filling the mold with molten alloy, removing bubbles, quenching the molten alloy in the mold, and then removing the mold.
