First 3D printed home in Kenya

Over three billion people are expected to need affordable housing by 2030. This issue is most acute in Africa, with countries like Kenya already facing an estimated shortage of two million houses. The start was made in October 2021 with 14Trees 3D printing a demonstration house in Nairobi, Kenya, which is also the first 3D printed house to achieve the IFC-EDGE Design Certificate.

The first 3D printed school

Located in Malawi, the world’s first 3D printed school was built using COBOD’s state-of-the-art BOD2 3D construction printer. The new technology also provides 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 3D printed by 14Trees using COBOD’s 4-4-2 model BOD2 construction printer, which can print concrete structures up to 10 meters in length and width and 3 meters in height.

The schools of the future

14Trees achieved tremendous results applying COBOD’s technology resulting in reduced cost, time, and materials compared to traditional methods. Furthermore, the building has an environmental footprint of 50% compared to the conventional building methods in Africa.
