Particle-Bed 3D Printing by Selective Cement Activation (SCA) – Sustainability, process enhancement and material models
The focus of this project is on particle-bed 3D printing (PB3DP) by Selective Cement Activation (SCA) with the aim to gain a fundamental understanding of the involved material-process interactions. In SCA a liquid is selectively applied on a dry particle-bed, consisting of fine aggregates and cement, so that the hydration reaction of the cement and thus the hardening only occurs locally. This process allows in particular the manufacturing of free formed elements with almost no restrictions in shape and topology.
Aim
The goal of this project is a fundamental understanding of the material-process interactions in particle-bed 3D printing by Selective Cement Activation. This is necessary to tailor both the material and the process to obtain the desired component properties.
Networking with other projects
TThe collaborations will specifically address the following aspects: The usage of RC material for SCA printing (A02), reinforcement integration (A05), computational modelling of the fluid intrusion into the particle-bed (B03), fracture analysis of hardened-state material (C01), shape optimisation of 3D printed elements (C02), sharing expert knowledge about SCA (C04), jointing principles (C05) and the evaluation of the ecological footprint of SCA printing (C09)
