The following paper deals with different methods of digitization for complex surfaces as well as computer numerically controlled production methods.

Based on an analysis and evaluation of current technologies in the field of 3D-Scanning and Rapid-Manufacturing a unique process was developed. This process bares resemblance to the action of photocopying but featuring an additional spatial dimension for process in- and output, with the omission of color.

Initially the user arranges physical objects. Subsequently the object relief is digitally recorded. The scan result is displayed as a grayscale image within a specifically developed software solution. Within this grayscale image the individual shades of grey represent the relief height information. According to the users preference the image can be modified within the scan-software or using an external image manipulation programm. Using specifically developed „vacuum-carving-tools“ a mold is carved into a bed of foundry sand and the final object can be cast.

Possible use cases for this process include various applications in the field of Architecture and Art.
