Bridging Scales – From Geometric Part Details to Construction Elements

Digital models for AM involve many different geometric scales. These scales start from micrometres for metal- or concrete-based processes. AM product scales, which are in the centre of this project, characterise parts as well as entire constructions and range up to tens of meters.


This project has closely connected central goals: The first one is to develop a consistent description for the relevant geometric models. The second focusses on efficient simulation methods for AM products in construction, based on the multi-scale geometric models. Finally, special emphasis is placed on validation of the developed techniques.

Networking with other projects

Project C01 is directly connected to all three focus areas of the AMC: The process simulation project B01, projects connected to the production technology (A01, A02, A03, A06 and A08) as well as the projects related to the design (C02, C04). We obtain experimental data such as geometric part details and material properties from the A projects and relay their part properties to the design projects. This loop is closed by a continuous verification and validation within C01 as indicated by the circular connection above. We also deliver our findings to C07 where technical regulations and qualification requirements are developed.
