Abstract
A method of making an object through investment casting includes additively manufacturing a mold for the object with a printing head on a carriage supported by a frame with the mold being additively manufactured from multiple layers on a build platform supported by the frame. An interior surface of the mold is machined with a machining device on the carriage after a predetermined number of layers have been added to the mold through additive manufacturing. The object is investment cast by directing a casting material into the mold while the mold is supported by the build platform.
