The first 3D printed building in Guatemala has been inaugurated through Central and South American cement company Progreso’s corporate accelerator. Danish 3DCP Group and COBOD International, using the BOD2 construction 3D printer, achieved another milestone—the 49 m2 house, which was 3D printed in 26 hours over seven days and features three-meter high walls, has taken major steps to verify the structural integrity of additive construction (AC) in a region prone to seismic activity. 3D printing enabled the organic shape of the house, which couldn’t be achieved with concrete blocks, but the rancho-roof features traditional palm leaves, which are inexpensive and offer thermal comfort; plus, due to their light weight and flexibility, they are also ideal for seismic regions.

“With immense satisfaction, we completed this unique project using 3D printing technology, once deemed distant. Progreso’s enduring spirit of innovation led us to explore new methods, culminating in a collaboratively designed building featuring a sustainable “rancho” roof, ensuring natural cooling in seismic regions,” said Plinio Estuardo Herrera, Manager of Concrete R&D at Progreso. “This achievement, a testament to our teamwork, harmoniously blends advanced technology with local traditions, thanks to the unwavering support of 3DCP Group and COBOD.”
