Abstract

The Cast Iron Museum at Sayn (Germany) hosts a wide range of historic cast iron objects ranging from highly detailed fly-size figures to oversize eagles and church bells. Replicating the historical cast iron, i.e. free formed objects, as miniaturized 3D prints for a new exhibition requires scanning to create the digital model. High quality of the digital model is a fundamental prerequisite for the production of the miniaturized 3D print. The influence of software selection and settings during data preparation from point cloud, mesh and finally solid is highlighted. Printing process selection is the final step in achieving the required print quality. A scanning and model generation strategy is developed and described using several exemplary objects from the Sayn Museum. The final print quality resulting from the selected scanning process is evaluated.
