Method of rapidly producing a contoured part, comprising: designing a computer graphic model of the part, sectioning the graphic model into graphic members which are at least one of blocks or slabs, carving a solid member (14-150 mm in thickness) for each of the graphic members, the solid member being proportion to and enveloping such graphic members, the carving being carried out by accessing two or more sides (opposite sides) of such solid member to at least essentially duplicate the corresponding graphic member, and securing the carved solid members together to replicate the graphic model as a usable unitary part. The method can be modified to make castings by carving wax or foam solid members which are assembled to form an investment pattern, the was pattern being used in a shell mold casting steps and the foam pattern being used in evaporative casting steps.

An engine component such as an intake or exhaust valve, or any other component near or within the combustion chamber, is coated with an amorphous hydrogenated carbon film coating to prevent the formation of carbonaceous deposits thereon. Methods for forming the film coating are also disclosed.
