For the additive manufacturing, three-dimensional model data are needed as input. The present master thesis describes the 3D scan as one of the possibilities to generate such model data. In addition, it explores the question of which scan technology is suitable for a possible future sample product for the TU Wien Pilotfabrik Industrie 4.0. For this purpose, the theoretical basis is initially formed by roughly explaining the mode of operation of the 3D scan and describing the main application areas. A classification helps to categorise the different scanning methods and show that there are fundamental differences between them. Selected technologies are described in detail and explained explicitly. In addition, application examples are given to clarify the difference between the methods. To better understand the process from the scan to the print, the process chain and transformation from the point cloud to a three-dimensional model will be described. This also includes the file formats of the individual data and explains their special features. After the theoretical basis has been described, based on defined criteria and considering given prerequisites, the specific 3D scanning technology is identified which is suitable for the virtual model of the possible example product. The comparison shows that photogrammetry is best suited. For the virtual model, the constructive considerations of the mechanical and electronic components are explained and the communication between the 3D scanner and a peripheral device is described. Finally, the prototype is described, with whose help the theoretical concept was proved. For this purpose, the construction is explained, and the focus laid on the digitization process and the required software.
