Power2build has completed its largest 3D printed building with a COBOD BOD2 site printer, using the D.fab concrete solution from COBOD International and CEMEX, in Angola. The company intends to transform the housing market and is a pioneer aiming to solve the affordable housing challenge in Angola, with 3D printed buildings.

The house is the second 3D printed residential building in Angola. It is a 140m2 house – consisting of a suite, two bedrooms, three bathrooms, a dining room and a living room. As the three bathrooms indicate, the house is not a social housing project, but rather a showcase of the design and architectural possibilities of 3D printed buildings.

Power2build is working with COBOD’s 3D printing technology to try to drastically reduce the housing shortage in Angola. 3D printing technology enables the construction of affordable, high-quality housing in the region – faster and more competitively.

Power2Build also printed Angola’s first 3D printed building – which was a 53m2 house. This house marked the start of a revolution, as it was the first 3D printed house in the world using real concrete (defined by a particle size greater than 8mm).

Angola was the first country in the world to print with the D.fab solution from COBOD International and CEMEX, making it possible to print real concrete. The solution has since been used in projects in Japan, Malaysia, Saudi Arabia, Ireland and Canada.

While Power2Build’s first house was printed in 48 hours, the second 140m2 house was printed in just 30 hours, a 4.5x improvement in productivity. On top of that, the team was able to do both the printing, and the water and electricity installations at the same time.

“We are very proud of our progress; people were wondering if we couldn’t print bigger. We have now printed a house 2.6 times bigger and in about 2/3 the time compared to the first house. We have remarkably improved the execution speed, but we still think there is room for improvement. In the future, we will only master this technology better. We are becoming more efficient every day and we are getting closer to achieving our vision of providing better housing at affordable prices to Angolan families,” said Ricardo Almeida, CEO of Power2Build.

The 3D printed house was made using the D.fab material solution – a revolutionary additive blend developed by COBOD and CEMEX, which allows printing with real concrete and saving up to 90% compared to printing with mortars. D.fab allows the use of 99% locally available materials and only 1% Magic Mix, supplied by COBOD. 3D printing with real concrete is a new direction for the construction 3D printing industry and serves as a gateway to properly commercializing the technology.

“We are proud to have developed the technology for this project. Power2Build has significantly increased its execution speed compared to their first and, now, second project. This is a great example of how we and our customers are continually improving technology and can build faster, better and cheaper as our customers and partners become experts in mastering 3D printing technology,” said Henrik Lund-Nielsen, Founder and Managing Director. of COBOD International.

COBOD International currently has six 3D printed buildings in Africa, all printed with COBOD technology. The company was the first (and only) company to print in Malawi, Madagascar, Kenya and Angola – two of which are schools and four are residences. Later this year, COBOD client 14trees will begin printing several new homes in Kilifi, Kenya.
