The great thing about 3D printing with multiple materials is that you no longer have to design for manufacture. A 3D printed engine, if it were possible, could have no cylinder head, no sump, no bolts, just printed with all the captive parts inside one solid shell.

There would then no longer be the manufacturing defects caused by poor production line management, any failure would be entirely down to the design of the part, as each one would be identical.
