3D printing in construction has come more into focus than ever before. According to a report from Exactitude Consulting, the market is expected to grow from $503M in 2020 to about $6.5B in 2029. And as readers may know, there are numerous projects already out there, including homes which are being lived in. As such, we decided to shine a spotlight on the many manufacturers of construction 3D printers who are driving this booming sector. Currently, there are a number of different types of construction 3D printers, from polar machines to gantry-mounted printers to mobile robots. Today, they are capable of extruding concrete that enable the construction of various structures of varying degrees of complexity, from houses to bridges and offices. In the following alphabetical listing, we take a look at the main manufacturers of 3D printed houses on the market!

Apis Cor

Apis Cor is an American company from Melbourne that developed a 3D printer capable of building a house in just 24 hours, in extreme weather. As for current technology, Apis Cor has a printer nicknamed ‘Frank’. This is an easy to handle mobile printer capable of creating buildings up to 3 floors. He does not require any additional assembly; he arrives at the site ready to work. ‘Frank’ has a younger ‘brother’ printer named Gary: he is in charge of ensuring a high quality of 3D printing material. But they also have a ‘sister’, ‘Mary’, who is in charge of 3D printing material supply. ‘Mary’ doesn’t need bags of material, getting dirty mixing by hand, rain or snow, ‘Mary’ is always ready to work – just add water, connect her to ‘Frank’ and ‘Gary’ for teamwork and build!

BatiPrint

BatiPrint is a project that came from a team of researchers from the University of Nantes, where the startup is still based. One of the most important manufacturers of 3D printed houses, it aims to accelerate 4.0 construction by building and renovating using robotics and additive manufacturing. For its solutions, it partnered with LS2N, a laboratory specialised in the development of robotics, to create a 4-meter-long robot that deposits 3 layers of materials in succession: two layers of expanding foam and one third of concrete. This industrial robot is polyarticulated and mobile, allowing it to operate directly on site. It is capable of building 7-meter walls. Additionally, the company turns to recycled or biosourced materials to help increase sustainability in construction. For their projects, we can point notably to the creation of the first social housing in Nantes.

COBOD

The Danish-based manufacturer of 3D printed houses, COBOD began its activities in 2017 with the construction of the first 3D printed building in Copenhagen. They are now present on every populated continent. The company’s first 3D printer was called BOD (Building On Demand) and with it they started working all over Europe, which allowed them to learn and optimize their machine. In this way they later developed the second generation of the 3D printer, the BOD2.  They have recently released the COBOD configurator which offers a digital version of the BOD2 printer, with adjustable printheads and size. There is even a simulation of their buildings under construction. Recent projects from the company include the first 3D printed office extension in Austria and the construction of the first two-story home in the US.

Constructions 3D

Constructions 3D is a French project by the company Machines-3D in collaboration with the Belgian architect Gaël Collaro, the leaders in 3D printing with mortar. The purpose of this project is to build customizable houses from recyclable materials directly in the locality where you want to create the construction, so they have developed their own 3D printers of houses. They currently have 3 printers. The Maxiprinter is the turnkey solution: a concrete printer which solves several problems faced by the construction industry. The transport of the container, as well as the robustness of the machine derived from its hydraulic system. They also have the Miniprinter Pro with a printing volume of 1.2 x 1.2 x 1.2 m which has an automated pumping system with 3 available pump options. And finally the Miniprinter Edu: designed to respond to the need of education and research sectors looking to develop the construction skills of their students and teams in relation to 3D digital tools.  The video shows one of their projects in Bruay-sur-Escaut, at the Citadelle des Savoir-Faire.

Contour Crafting

To build the average home in the U.S., it takes between six and nine months. Now imagine what it would be like if a personalized house could be built in just one day. Contour Crafting has addressed this issue. Thanks to advanced robotics, they able to build custom homes in just a few hours. Whether for low-income people or to rebuild after disasters – and for just one-fifth of the traditional cost of building a house! As for the material used for the 3D printer by Contour Crafting, this uses a fast-setting, concrete-like material.

Cybe Construction

CyBe Construction is a Dutch company that had previously launched 2 3D concrete printers, Cybe RC 3Dp and Cybe R 3Dp. It has now launched a third Cybe G, a 3D printer of a four column, three beam configuration capable of printing anywhere within the set 3D zone. This printer is perfect for construction companies interested in building affordable housing. The gantry prints with a print head and nozzle controlled by ABB. But not only that, they have also developed a patented material, based on a concrete mix. Both machines with 6 axes could print at a speed of 200 mm/second, enabling concrete structures to be manufactured quickly. Cybe’s technology is considered to be one of the most innovative and reliable ways to build a concrete unit.
