CREATE is the group for Computational Research in Emergent Architectural Technology, founded and directed since 2018 by Associate Professor Roberto Naboni. The group is based at the TEK Faculty of the University of Southern Denmark (SDU), and it is an integral part of the section of SDU Civil and Architectural Engineering (CAE).
How can we use 3D Concrete Printing and performance-based design to reduce the weight of horizontal structures?
Combining computational design and the freedom of shape provided by 3D Concrete Printing (3DCP) technology, the ongoing research project 3DLightBeam - 3D Printed Lightweight Beam challenges conventional reinforced concrete structures by exploring new design solutions for lightweight load-bearing concrete beams.
A series of full-scale reinforced concrete beams are 3D Printed in the Robotic 3DCP fabrication cell of the CREATE Lab and tested at the Concrete Lab at SDU. Working towards the reduction of material usage, the design studies look at the material optimization and characterization for solid beams, the opportunities enabled by functionally grading applied to controlled toolpath generation for porous, stress-based 3D modelling. The produced structural elements take advantage of the high control over the printing parameters such as speed, layer width and height to optimize the final outcome.
The project is linked to parallel investigations on the anisotropic behaviour of 3DCP structures, where a series of specimens are tested for compression strength and rebar-concrete bonding with different printing directions.
