SV3DPrinter

In the heart of Guatemala, where the ground occasionally trembles with seismic forces, a remarkable feat of engineering has been accomplished. Cement company Progreso has unveiled the nation’s very first 3D-printed building, designed with a steadfast resolve to withstand the local seismic challenges. This remarkable prototype not only showcases modern 3D printing techniques but also pays homage to traditional craftsmanship in the form of a charming thatched roof.

COBOD’s BOD2 3D printer, renowned for its work on India’s post office and Europe’s first two-story 3D-printed house, played a pivotal role. The construction process was akin to its predecessors, with the 3D printer meticulously extruding layers of a cement-like mixture. According to a pre-planned blueprint. Remarkably, this entire printing process took just 26 hours, though it was spread over a span of seven days. Following the completion of the concrete shell, skilled human builders added windows, wiring, plumbing, and other essential elements. They even gave the house its traditional palm-thatched roof, known as the ‘Rancho’ type, a lightweight and flexible material ideally suited for seismic regions.

The project’s press release lauded the success of validating the structural viability of 3D construction printing in a region prone to seismic activity. The most remarkable aspect lies in the highly organic-shaped walls achieved through 3D printing. These intricate designs would have been prohibitively expensive or even unfeasible with conventional concrete block construction, the predominant building method in the region.The 3D-printed house offers a minimalist, utilitarian interior, emphasizing its prototype status. Spread over one floor, it spans 49 square meters (527 square feet). The interior features a central living area, complete with a table and chairs, alongside a compact kitchen area equipped with cabinetry and a sink. An adjoining room seems configured for office use but could easily serve as a bedroom. The house also houses a bathroom, ensuring it remains a fully functional dwelling.

While this remarkable project currently stands as a research tool, there’s no immediate plan to scale it up. Yet, it serves as a testament to human ingenuity, merging cutting-edge 3D printing with a deep respect for local tradition. The earthquake-resistant 3D-printed house is a symbol of innovation and resilience, offering a glimpse into the future of sustainable and secure housing.
