Project Content: 3D Survey, Modelling and 3D PrintingProject Progress: The project task was to document the bust of Emperor Wilhelm II in 3D and generate a 1:1 replica. The bust, made by Walter Schott, was surveyed on site within a few hours. The result of this 3D survey and 3D analysis is a 3D model of the bust, which was the basis for the 1:1 replica. The reproduction was done using a 3D printing layer system produced in several individual parts and assembled like a 3D puzzle.To digitise the bust we used the Artec TM Eva 3D Scanner (RSI GmbH). The surface was illuminated using structured light which was recorded with high-speed cameras.
Using the known recording configuration of the surveying system and the measurement pictures, real-time 3D-coordinates of the surface were deducted.Within the post processing the different scans were aligned within a common reference system, redundant overlapping removed and all merged into a 3D-model – consisting of 12. million polygons (triangles).
