3D Structural Puzzle – Numerical Multi Scale Shape and Topology Optimisation Methods to Additively Manufacture Optimal Structures from Optimised Pieces (C02)

• Subject Area: Architecture, Building and Construction History, Construction Research, Sustainable Building Technology ; Applied Mechanics, Statics and Dynamics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 414265976

In the 1st funding period, the project dealt with structures made of large three-dimensional components produced by additive manufacturing, focusing on the structural optimisation of the individual parts. The proposed 2nd funding period consolidates and significantly extends this concept to a Holistic Design Framework (HDF) for Additive Manufacturing in Construction. The proposed HDF will leverage an entirely novel multi-fidelity, multi-scale and multi-material approach. The multi-fidelity feature will enable a bi-directional interaction between low-fidelity models (discrete networks) and high-fidelity finite-element-based models (continuous geometries). The HDF will lead to material savings by designing efficient structural forms that can be realised through Additive Manufacturing.
