Abstract: A method including: obtaining a part design file of a part; deriving, from the art design file, a central mold design; determining one or more fill points for the central mold design; and attaching one or more mating connectors to the determined one or more fill points to create a modular part mold file.

Abstract: Aspects of the disclosed technology include an additive manufacturing method including: applying a mixture of metal powder and a carrier agent to a substrate; removing a portion of the carrier agent from the applied mixture; and fusing the metal powder remaining in the applied mixture to the substrate.

Abstract: A system including: an optical light source; a reservoir configured to hold a liquid photosensitive medium that is adapted to change states upon exposure to a portion of light from the optical imaging system; and a control system configured to control the optical light source to expose specified portions of a surface the photosensitive medium contained in the reservoir to light from the light source. The control system may be further configured to control the optical light source to repeatedly expose the surface of the photosensitive medium contained in the reservoir to light from the light source to build layers of a desired object.
