Additively produced coated foundry tooling

A method of manufacturing a casting, the method comprising the steps of:

• manufacturing a foundry tooling body, the step of manufacturing the foundry tooling body comprising the steps of:
• forming a foundry tooling body in accordance with a predetermined model;
• and
• coating the foundry tooling body using PVD to add a metallic coating to at least a portion of the foundry tooling body to define at least one coated tooling body surface, wherein each coated tooling body surface is configured to contact a malleable blank to produce a sand mold suitable for manufacturing a casting,
• wherein the foundry tooling body defines a first configuration;
• loading the foundry tooling body into a molding machine;
• using the molding machine to bring the foundry tooling body into contact with a malleable blank comprised of a mixture of sand and a resin;
• and
• using the molding machine to further urge the foundry tooling body toward the malleable blank such that the foundry tooling exerts pressure upon the malleable blank until the malleable blank transforms into a sand mold, the sand mold defining a second configuration complementary to the first configuration, wherein the second configuration defines at least one sand mold cavity.
