An entire school 3D-printed in just 18 hours printing time

Malawi, Africa

14Trees is a joint venture of Holcim and CDC Group dedicated to accelerating the provision of affordable housing in Africa. Together with their bank & contractor partners, 14Trees strives to make green and affordable housing a reality. Located in Malawi, the world’s first 3D printed school was built using COBOD’s state-of-the-art BOD2 3D construction printer. In alignment with the United Nations’ Sustainable Development Goals, intended to address the global challenges humanity faces, the school was built with the goal of accelerating the provision of affordable housing and schools across the continent of Africa. The new technology also brings about opportunities for local people to be trained as 3D construction printer operators and specialists creating new jobs and skilled workers. The school building in Malawi, measuring 56 m2 was built using COBOD’sr 4-4-2 model BOD2 construction printer, which is capable of printing concrete structures up to 10 meters in length and width, and 3 meters in height.

14Trees achieved tremendous results applying COBOD’s technology resulting in reduced cost, time, and materials compared to traditional methods. Furthermore, the building also has an environmental footprint of 50% compared to the traditional building methods in Africa . “I am very impressed by the new building – its durability and design provide the space and facilities that students did not have before. This school will attract more students, and those learners that had left will return to education,” says Juliana Kuphanga Chikandila, Primary Education Advisor, representing the Director of Education, Youth, and Sports in Malawi.

COBOD wants to accelerate the development process of critical infrastructure and thereby solve the shortage of schools and affordable houses in Africa.
