Abstract: Modern production systems produce serial parts on the basis of 3D CAD data. With the reproduction of spare parts often come different requirements: missing 3D CAD models and low quantities make it difficult to produce economically and with flexible production units. The possibility of generating 3D CAD data of an existing original part with the help of conventional measuring systems is practically possible only with simple geometries. Complex geometries such as cast parts with undercut and inner contours cannot be collected non-destructively. In order to present a reproduction process that can also handle complex cast parts, the process of Rapid Cloning was developed and successfully tested with a historical aluminium cylinder head. The inner and outer contours of the complex casting were first obtained using industrial computer tomography (CT), a non-destructive measurement. The 3D data obtained was then utilised in subsequent steps, such as the process simulation and the design of the core package. Each designed core was then produced using a Selective Laser Sintering (SLS) Rapid Prototyping (RP) system. This process allows to receive a fully functional clone of the cylinder head within a few weeks. This development in rapid reproduction is applicable to most existing castings.
