The world’s first 3D-printed school was opened in Kalonga Village, Malawi in June 2021. It was built by 14Trees, a joint venture between Holcim and CDC Group. The school was printed, using a specially designed 3D printer that can print walls up to 10 meters long. The school was built in just 18 hours using a 3D printer that extruded a mixture of sand, cement, and water.

The 3D-printed school in Kalonga is a significant milestone in the development of 3D printing technology for construction. It shows that 3D printing can be used to build high-quality, sustainable schools quickly and affordably. This has the potential to revolutionize the way schools are built in developing countries, where there is a shortage of classrooms.

The school in Malawi is a prototype, but 14Trees plans to build more 3D-printed schools in the country in the future. The company also plans to expand its operations to other African countries.

Overall, 3D printing has the potential to revolutionize school construction in developing countries. It is a promising new technology that can help to ensure that all children have access to a quality education.
