Print 3d building
Largest 3D printed building in Africa
- Power2Build finished their second and largest 3D printed building yet in Angola with the BOD2 construction printer.
- 140 m2 house printed 4,5 times faster than the first 3D printed building Power2Build made.
- D.fab concrete solution from COBOD International and CEMEX enabling cost-saving up to 90% – first shown in Angola, now spread all over the world.
- COBOD completely dominates the 3D construction printing market in Africa with the six 3D printed buildings, all done with COBOD technology.
Power2build have recently finished their largest 3D printed building with a COBOD BOD2 construction printer in Angola. The company has set out to transform the housing market and are pioneers aiming to solve affordable housing in Angola with 3D printed buildings.
The house is the second 3D printed residential building in Angola. It is a 140 m2 house that holds a suite, two bedrooms, three bathrooms, a dining room, and a living room. As the three bathrooms indicate, this is not a social housing project, but rather a house showcasing the design and architectural possibilities of 3D printed buildings.
Power2build is working with COBOD’s 3D printing technology to significantly reduce the housing shortage in Angola. The 3D printing technology is an innovative method that allows construction of affordable and high-quality housing in the region in a faster and more competitive way.
Power2Build printed Angola’s first 3D printed building – a 53 m2 house. This was an incredible milestone, marking the beginning of a revolution, as the house was the world’s first 3D printed house in real concrete (defined by particle size above 8 mm).
While the first house was printed in 48 hours, the second house with 140 m2 was printed in 30 hours. This equates to a 4,5 times improvement in productivity. In addition to this, the team was able to both do the printing, and the water and electrical installations at the same time.
Ricardo Almeida, CEO from Power2Build said: “We are very proud of our progress; people were questioning if we couldn’t print bigger. We have now printed a 2,6 times bigger house and in about 2/3 of the time compared to the first house. We improved the speed of execution remarkably, but still believe there is room for improvement. In the future we will only become better at mastering this technology. We are getting more efficient by the day and closer to achieving our vision to deliver better housing at affordable prices to Angolan families.”
Angola was the first country in the world that printed with the D.fab solution from COBOD International and CEMEX, making printing of real concrete possible. The solution has since been used in projects in a.o. Japan, Malaysia, Saudi Arabia, Ireland and Canada.The 3D printed house was done with the D.fab material solution, a ground-breaking additive mix developed by COBOD and CEMEX, that enables printing with real concrete, leading to cost-savings of up to 90% compared to printing with mortars.
D.fab enables the usage of 99% locally available materials and only 1% Magic Mix supplied by COBOD. 3D printing with real concrete is a genuine step change in the industry of 3D construction printing and serves as a prominent gateway to properly commercializing the technology.
Commenting on the successful build of the house, Henrik Lund-Nielsen, Founder & General Manager of COBOD International said: “We are proud to have made the technology for this project. Power2Build have increased their speed of execution tremendously compared to their first and now second project. This is a great example of how we and our customers are continuously improving the technology and can build faster, better, and cheaper as our customers and partners become experts at mastering the 3D printing technology.”
COBOD International’s 3D construction printing technology is dominating the market in Africa, which so far has six 3D printed buildings all done with COBOD technology. The company was the first (and only) to print in Malawi, Madagascar, Kenya, and Angola, two of which are schools and four residentials.
Later this year COBOD’s customer 14trees will begin printing a double-digit number of houses in Kilifi in Kenya.
World leader in 3D construction printing solutions with +50 printers sold world-wide.
COBOD’s mission is to build smarter through multifunctional construction robots based on 3D printing technology and COBOD’s vision is to automate minimum 50% of construction processes on building sites. All leading to better, faster, cheaper and more sustainable construction than conventional concrete. We constantly strive to reduce the co2 footprint of 3D printed concrete.
COBOD’s 3D printers made Europe’s first building in 2017. Subsequently our printers made the first 2- and 3-story buildings in Europe (Belgium & Germany), North America (US & Canada) and India.
Also, the first 3D printed villa in Dubai and buildings in Africa have been done by COBOD 3D construction printers, just like the first wind turbine bases.
COBOD has an open-source material strategy, partnering with customers, academic institutions, and suppliers around the world.
COBOD is privately owned by General Electric, CEMEX, Holcim and PERI as key shareholders, and our partners further include Dar Al Arkan (Saudi Arabia), L&T Construction (India), JGC (Japan), Siam Cement (Thailand) and Orascom (Egypt).

Recently, much attention has been paid to the printing of buildings, and printed houses are increasingly appearing in recent years in different countries of the world - in the USA, Saudi Arabia, Mexico, France, Russia, the United Arab Emirates and others.
I have prepared a list of existing 3D printed buildings for 2020.
What is a 3D printer for construction.
Today's 3D construction printers differ in designs and wall construction methods. The most common printers are portal construction, two- and four-support construction, on the basis of a manipulator arm or a circular design. The equipment allows you to create small architectural forms and elements of structures for their subsequent assembly on site, or allow you to print the entire building on the construction site. The height and dimensions of the printed building depend on the specifications of the printer being used.
How the printing process works.
The extruder extrudes a fast-hardening concrete mixture with various additives. Each subsequent layer is applied on top of the previous one, due to which a vertical structure is formed. The concrete layers below are thus compacted, thereby increasing their ability to withstand the next layers, and hence the entire weight of the structure.
To strengthen the structure, it is reinforced, which can be both vertical and horizontal. The laying of the horizontal armored belt is carried out between the layers, the vertical reinforcement is installed after the composition has hardened, and then it is poured with concrete.
Advantages of 3D printing over other construction methods.
3D printer fabrication opens up great opportunities for construction and related industries. Practical application has revealed the following advantages of additive manufacturing:
- It removes the limits from the imagination of designers and architects who design buildings, as it provides opportunities that are not available with the construction methods we are used to.
- High speed of construction of buildings and structures.
- Complete process automation.
- Low power equipment.
- Significant savings compared to conventional construction methods by reducing labor and energy costs and accelerating construction time.
- The formation of waste building materials is completely eliminated.
- Minimization of human intervention in the construction process not only allows building in places inaccessible to people, but also eliminates the human factor in ordinary territories and reduces the likelihood of error.
1. June 2014. China. China's Shanghai WinSun Decoration Design Engineering Co has unveiled 3D printed houses at an industrial park in China's Jiangsu province. A total of ten houses were created, each of which cost a little more than three thousand pounds sterling. Over the next ten months, the technology improved and the company produced several different types of buildings for the exhibition, the tallest of which has five floors.
2. August 2014. USA. Andrey Rudenko's company Totalkustom printed the lock. The printing took a total of 2 months. The machine's printing speed was 50 cm in 8 hours.
The main part of the castle, measuring 3m x 5m and 3.5m high, was printed as a single unit, and the towers were then printed separately.
3. July 2015. China. Chinese company Zhuoda assembled a two-story house in record time. The modular home, made up of six 3D printed modules, was assembled on site in less than 3 hours. Of course actually about 90% of the work was carried out in the company's workshops, and on the site they were only assembled into a single building.
4. September 2015. Philippines. Andrey Rudenko's Totalkustom company built apartments on the territory of a hotel in the Philippines, 10.5 mx 12.5 m in size and 3 meters high. The building was built using local materials - sand and volcanic ash.
5. May 2016. UAE. Chinese company Shanghai WinSun Decoration Design Engineering Co printed prefabricated structures for the subsequent assembly of an office building in Dubai. The area of a one-story building is about 250 square meters.
m.
6. March 2017. Russia. Apis Cor introduced the first 37 sq. m.. The printed house has an interesting shape, but as the participants themselves say: this is just to show the flexibility of printing technology, the shape of the buildings can also be the usual square. Compared to other construction 3D printers, this printer is very compact (4×1.6×1.5 m), weighs 2 tons, and can be easily transported to the construction site.
7. October 2017. Russia. In Yaroslavl, the company Spetsavia presented the first residential building in Europe and the CIS, built using construction 3D printing technology. Construction of the house began in 2015. The box of the building was printed by a portal printer piece by piece and then assembled on the foundation in one month in December 2015. In the summer of 2017, the roof was completed and the bulk of the interior finishing work was carried out.
8. March 2018. France. Yhnova presented a five-room one-story house with an area of 95 square meters.
For its construction, the engineers used a large manipulator, at the end of which an extruder for polyurethane foam is fixed. While working, he applied the foam in accordance with the 3D model of the building loaded into it. After applying the foam, the builders periodically filled the erected part with concrete, and also inserted the frames of doors and windows.
9. March 2018. USA. American Company Icon built a prototype home in Texas to prove the technology's performance. The area of the building was 32 sq.m., printing was performed by a portal type 3D printer moving along rails installed on the site.
10. July 2018. Spain. Be More 3D printed a 24 m2 concrete building. For the construction, a two-support 3D printer was used, the width of which is 7 meters and the height is 5 meters.
11. September 2018. Denmark. 3D Printhuset printed a 50 square meter office in Nordhavn. The 3D printer used for printing is of the portal type and has a size of 8 x 8 x 6 meters.
Print speed 2.5 meters / min. Each layer is 50-70 mm. The print material is concrete made largely from recycled tiles and sand.
12. October 2018. Italy. Company Crane Wasp using a three-bearing construction 3D printer erected a building in ten days. The house uses passive solar heating technology and natural ventilation. The composition for printing was created on the basis of waste from rice cultivation (it was 25% local soil (clay and sand), 40% straw, another 25% - from rice husks and 10% - from hydraulic lime).
November 13, 2018. Italy. Arup in collaboration with the architectural bureau CLS Architetti erected a building in 1 week with an area of 100 sq.m. The building was printed in segments with subsequent assembly at the construction site.
November 14, 2018. Saudi Arabia. The Dutch company CyBe Construction has completed the construction of a building with an area of 80 sq.m. It took about a week to 3D print the necessary elements, and a little more than a day to assemble.
The walls are made up of 27 printed blocks, and the parapets needed another 21 blocks to make.
15. August 2019. USA. S-Squared 3D Printers (SQ3D) showed a prototype residential building that can be built from floor to roof in just twelve hours. The house has an area of 46 m2. During the printing process, a 3D printer of a two-support design was used.
16. October 2019. UAE. Apis Cor has announced the completion of the world's largest 3D printed building. Located in Dubai, the 650 sq. meters has a building height of 95 meters and entered the Guinness Book of Records as the largest building printed directly on the construction site.
17. December 2019. Mexico. American company Icon erected two residential buildings for the non-profit organization New Story, in southeastern Mexico. The imprinted buildings have a flat roof, curved walls and an area of 46.5 square meters
As can be seen from the impressive list of completed projects, progress in the field of construction 3D printing clearly does not stand still, new techniques are constantly being introduced, various materials are being created, including from recycled raw materials, and high-tech equipment is being developed.
In a short period of time, the technology has attracted the interest of a large number of enterprises that are engaged in the development of equipment, special building mixtures, libraries of structural solutions for designing buildings for 3D printing, as well as the preparation of a legislative, regulatory and regulatory framework.
I am sure that in the future the entire construction process will be able to become fully automated, without human intervention, not only when printing foundations and walls, but also when printing ceilings and roofs, automatically install utilities, doors and windows. Also, perhaps in the future we will not be limited to printing houses of 2-3 floors, but will be able to move on to multi-storey construction. All this is no longer something impossible and has ceased to sound like fantastic dreams of a high-tech future. It is only necessary to give time for the natural evolution of 3D construction technology.
