Guide: By 2030, more than 3 billion people worldwide are expected to facehousingcrisis. This problem is most serious in Africa. Countries such as Kenya are said to have faced a shortage of 2 million housing units. In October 2021, COBOD built the first building in Nairobi, Kenya3D printingDemonstration house, this is also the first to obtain IFC-EDGE design certificate3D printinghouses.

3D printing service14Trees (a joint venture of Holcim and CDC Group) is using COBOD BOD2 3D construction printers to accelerate the construction of affordable housing in Africa. It is reported that 14Tree will begin printing 52 affordable housing units in Kilifi in the first quarter of 2022, similar to the Nairobi building. The project is claimed to be one of the largest 3D construction projects in the world.

14Trees is a joint venture between Holcim, the world’s leading building materials company, and CDC Group, a British development financial institution. Committed to bringing innovative construction methods from the laboratory to the site, testing, optimizing, implementing and scaling up.Currently, this company is focusing on making Africa green and lowincomeAnd affordable housing becomes a reality. It is understood that Mvule Gardens has obtained IFC’s Edge Advanced Design certification, which reflects the environmental protection characteristics of the house.

There are three types of 3D printed houses in Mvule Garden by 14Trees: one-bedroom house, two-bedroom house and three-bedroom house. These 3D printed houses have spacious rooms with an open layout to get more natural light. The house has a front balcony and a private backyard. In addition, the location of the building is close to the park and the road is convenient. And the price of these houses is in the range of 24-450,000 Kenyan shillings (1.38-25,400 yuan). It is indeed quite affordable!

The project is manufactured by Holcim’s proprietary ink TectorPrint, which enables the wall structure to withstand the building load.Compared with traditional craftsmanship, the new technology reduces the environmental footprint by more than 50% and reducesstandardTypical CO2 emissions from cement production methods. In addition, 14Trees also uses natural fiber ingredients to strengthen the practice of 3D printing in African buildings and create local technical jobs in areas such as sustainability and 3D technology operations.

The new 52-family residential community will become part of the Green Heart of Kenya’s regenerative ecosystem, which is a model of Kenya’s inclusive and climate-resilient city. In addition, the architectural design of MASS Design Group, an architectural practice company in the United States and Africa, provides modern and reproducible housing units to meet the needs of low-income families.

It is reported that 14Trees will begin construction of Mvule Garden in the first quarter of 2022. This innovative project is considered a valuable, fast and economical solution to the housing shortage in sub-Saharan Africa (estimated at 50 million units).

Africa’s first 3D printed house and school
On December 7, 2021, Kenya’s first 3D printed house, TreesHouse No. 0, officially opened in Athi River, Machakos County, marking3D printing technologySuccessfully entered the Kenyan construction market. 14Tree printed the entire wall within 12 hours. At the same time, the use of architectural 3D printing can save up to 20% of construction costs.

The two-bedroom house located in the Bamburi Special Products site is the product of 14 Trees, a joint venture between Bamburi Cement’s parent company Holcim and the British development financier CDC Group. Now, this house will serve as a model house for the proposed Mvule Gardens.

Earlier, in June 2021, the world’s first 3D printing school at 14Trees was completed in Malawi. It is understood that Africa has a huge deficit in schools. UNICEF estimates that in Malawi alone, there is a shortage of 36,000 classrooms. It takes 70 years to build using traditional methods and speed. And 14Trees said that the use of 3D architectural printing technology can bridge the gap in infrastructure in just 10 years, and this new technology has been well received in the country.
△Malawi School
According to 14Trees, the children have already started to attend school. In addition, these 3D printed walls were produced within 18 hours. The school in Malawi has a total area of 56 square meters and is made using COBOD’s BOD2 model 4-4-2, which can print concrete structures up to 10 meters in length and width and 3 meters in height.

In addition, 3D printed houses are being actively promoted in rural areas in China.Depend onThe 3D printing farmhouse project proposed by Professor Xu Weiguo of the School of Architecture of Tsinghua University was completed in Zhangjiakou, Hebei Province in November 2021., Has received a lot of attention. I believe there will be more similar cases in the future, and the Antarctic Bear is very much looking forward to it!
