The construction industry faces critical challenges such as sustainability, rising costs, and skilled labor shortages. 3D Concrete Printing (3DCP) offers practical, innovative solutions to these issues, reshaping how architects and designers approach building construction. This seminar highlights two impactful projects from Madagascar, demonstrating how 3DCP, coupled with computational design tools like Grasshopper, enables architects to create structures that are sustainable, efficient, and uniquely suited to local needs. By optimizing form and material use, these projects significantly reduce waste, carbon emissions, and construction time. Beyond technology alone, the session emphasizes the necessity of collaboration between architects, designers, engineers, and contractors to overcome barriers to adoption where submissions are not in traditional 2d drawings but digital twins. Attendees will gain a clear understanding of how integrating computational design with 3DCP can realistically transform architectural practice, positively impacting communities and setting a new standard for sustainable construction.
