TECHNIQUES FOR A VIENNESE SYNAGOGUE

In the framework of a preceding SiGraDi-conference the virtual reconstruction work of Viennese Synagogues was elaborated. The focus of this continued research project is laid on historic/reconstructive modeling, which has specifi c requirements towards the modeling and subsequent production of scale models. In this paper, the prerequisites of 3D-printing and lasercutting technology for model making will be presented. This includes aspects of scale and handling of individual building elements regarding the possibilities and limitations for each specifi c CAM-technique. Compared to the rendering models, the modeling procedures for scale-model fabrication had to be adjusted. For example, certain dimensions for details and the structural strength of 3D-printed parts have to be taken into account. Due to economical and constructional reasons as well the printing time involved, a scale-model should be created by means of mixed CAM-techniques; building components have to be split up and assigned accordingly. 1
