World's first test shakes 3D-printed homes to check earthquake safety

The University of Bristol has conducted the world’s first large-scale earthquake safety test on a 3D-printed concrete home using the UK’s largest shaking table. This experiment aimed to evaluate whether 3D-printed homes can withstand seismic forces, addressing concerns about the structural integrity of this emerging construction method. By subjecting a quasi-real-scale 3D-printed concrete unit to progressively intense shaking, researchers closely monitored its response to identify potential weaknesses such as cracking or displacement. The goal is to compare 3D-printed structures with traditional buildings, validate computational seismic models, and ultimately determine if 3D-printed concrete can meet current earthquake safety standards. The project, led by Dr. De Risi, seeks to optimize design parameters like layer bonding and reinforcement integration to improve seismic performance. These findings are intended to inform engineers, architects, and policymakers, potentially leading to new building codes that incorporate additive manufacturing technologies. As 3D printing gains popularity for its affordability and sustainability, this research addresses
