14Trees, a joint venture between building materials specialistLafargeHolcim和CDC Group, the UK’s publicly owned impact investor, is building Africa’s largest 3D printed affordable housing project in Kenya.
这个52 House社区将位于蒙巴萨以北的基利菲镇，并将成为肯尼亚再生生态系统的一部分，支持肯尼亚总统肯雅塔的“ 4巨头”议程，以增加该地区的负担得起的住房。
“We are excited to be building one of the world’s largest 3D printed affordable housing projects in Kenya,” Jan Jenisch, CEO at Holcim. “With today’s rapid urbanization, 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.
“By deploying 3D printing, we can address this infrastructure gap at scale to increase living standards for all.”
解决非洲的住房危机
14Trees first embarked upon its mission to buildaffordable and low-carbon housing and schools in Africa去年，从莉隆威（Lilongwe）的一间原型房屋开始，以及马拉维萨利玛（Salima）的一所学校。据报道，萨利玛学校于7月完成，据报道世界上第一间印刷学校和has already welcomed students through its doors.
该项目是rolled out to Zimbabwe earlier this yearto address the country’s chronic housing and infrastructure shortage and to showcase the capabilities of 3D printing for construction.
Now, 14Trees is extending its 3D printed affordable housing project to Kenya as it continues to support Africa’s construction sector and develop 3D printing technology across the continent.

14Trees’ 3D printing construction project utilizes Holcim’s proprietary ink, TectorPrint, combined with a BOD2 robotic 3D construction printer provided by Danish 3D printing construction firmCOBOD. The combination reportedly reduces the environmental footprint by more than 50 percent compared to traditional construction processes, and emits lower CO2 emissions than standard methods of cement production.
TectorPrint gives the 3D printed walls the structural function to bear the load of the building, while the BOD2 is capable of printing concrete structures up to 10 meters in length and width, and three meters in height.

The new complex in Kenya, called Mvule Gardens, will see 52 affordable homes built using 14Trees’ 3D printing technology. The complex has been purpose-designed by the US-Africa-based architectural firm MASS Design Group, which seeks to provide modern and replicable housing units adapted to the needs of underserved communities among lower-income households.
14Trees ability to provide a rapid and economical method of solving Africa’s housing deficit, which is estimated at some 50 million units, will also help to create locally-based skilled jobs within sustainability and 3D technology, as well as other areas.
The project has won the IFC-EDGE advanced sustainable design certification, which recognizes resource-efficient and zero-carbon buildings, with construction starting in the first quarter of 2022.
“14Trees is pioneering the use of leading-edge technology to address one of Africa’s most pressing development needs – affordable housing – to create life-changing infrastructure for whole communities,” said Tenbite Ermias, Head of Africa and Africa Managing Director at CDC Group.
