Abstract: Methods of manufacturing engines are disclosed. A single-piece core is printed based on specifications in a three-dimensional print file. The single-piece core is then used in a casting process to create an engine. The three-dimensional print file includes specifications corresponding to each hollow interior feature of an engine. The three-dimensional print file may include specifications for one or more accessory features, and the single-piece core may be printed to include the one or more accessory features.
