Particle Bed 3D Printing by Selective Cement Activation (SCA) – Sustainability, Process Enhancement and Material Models (A01)

• Subject Area: Construction Material Sciences, Chemistry, Building Physics ; Mechanical Process Engineering
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 414265976

The goal of this project is a fundamental understanding of the material-process interactions in particle-bed 3D printing by Selective Cement Activation. Special focus is on basic research addressing the environmental sustainability, i.e. reducing the material’s CO2-footprint as well as the enhancement of the SCA process regarding an automated process-parallel reinforcement integration, novel approaches of graded and multi-material printing as well as excavation strategies. To get a fundamental understanding of the printed material properties we further aim to develop models describing particle-bed compaction, fluid intrusion as well as constitutive material models for the hardened properties. We furthermore intend to investigate the possibilities of topology optimisation and segmentation.
