Combined technology investment casting process

摘要

A method of fabricating a finished part includes generating or creating a master pattern using an additive manufacturing process, and the master pattern corresponds in shape to the finished part. A shell is created by applying one or more layers of one or more coating materials to the master pattern. The master pattern is then dissolved while the master pattern is in the shell to create a cavity in the shell that corresponds in shape to the finished part. A molten material is then poured into the cavity of the shell. The molten metal is allowed to cool and to harden and/or to reach a determined temperature such that the molten metal becomes the finished part. The shell is then removed from around the finished part.
