On 18-20 January at the Las Vegas Convention Center during the World of Concrete convention, COBOD International, together with materials provider QUIKRETE and Arizona 3D builder & developer We Print Homes 3D-printed building structures in front of large live crowds for 3 days in a row at the World of Concrete show. World of Concrete is the world’s largest convention for concrete and construction with approx. 37,000 attendees and 1,100 vendors in 2022.
The exhibition demonstrated the increased interest in 3D construction printing technology as a viable. and competitive alternative to conventional construction

3D concrete printing, or 3DCP, holds the key to disrupting the construction industry by automating core building processes, making construction faster, cheaper, more sustainable, while providing added design freedom. COBOD has spearheaded the development and since 2019, COBOD has on 6 continents sold 35+ 3D construction printers, which have been used for among other the first 1-, 2- and 3-story 3D printed buildings in Europe, the first 3D printed house and school in Africa, and the first wind turbine tower base made in cooperation with GE Renewable Energy. In the US, COBOD’s printers have been used to make houses in 3 different US states so far.
To demonstrate the market readiness of the technology and its widescale applicability in the US, COBOD decided to demonstrate their printing system at a large US construction event. COBOD’s printing system is capable of printing with mortars as well as being the only printer in the world to print real concrete. At the World of Concrete, the COBOD BOD2 printer used a mortar mix from QUIKRETE and demonstrated continuous 3D printing of a wall structure over 3 days in a row increasing the height daily and during printing the crowd had the opportunity to ask questions and get explanations to various aspects of the printing process.
The live printing attracted a crowd of more than 1,000+ people and was very popular. World of Concrete (woc360.com) even labelled the live printing as a “must-see” exhibition, further underlining the increased interest and attraction of the 3D printing technology.
Commenting on the success of the live 3D printing, Philip Lund-Nielsen, Co-founder & Head of Americas at COBOD, said: “Our goal with 3D printing in front of a live audience at World of Concrete was to demonstrate the advantages of our technology in US as our main market, at the same time demonstrating that our technology is reliable and ready to be used in the US. We wanted to show that 3D construction printing is not just a lab idea, but a viable and competitive alternative to traditional construction methods. The massive number of inquiries during and after show tells me that we succeeded with our goals.”
Martin Cardoine, Manager of Precise Contracting, Tennessee, voiced his excitement of the live 3D printing demos:
“It was thrilling to see COBOD’s BOD2 printer live in action and being able to have conversations face to face with the technology provider, a materials expert, and an existing customer from the US. We are looking very much forward to getting started with our own 3D construction printing projects in a few months, pioneering COBOD’s technology in our state.
As a further sign of the increasing popularity of COBOD’s technology, the educational event which COBOD also hosted during the World of Concrete had more than 150+ attendees and the lecture room had to be upgraded twice to accommodate everybody.
On the success of the educational events, Alma Bangsgaard, Architect and Project Manager, COBOD added:
“From COBOD’s side we were happy to share with the attendees all our accumulated knowledge from working with our 32+ customers across the globe. We especially enjoyed the discussions on how new developers and builders go from planning to printing, which attendees could then experience live outside shortly after. We also noticed that some of our so-called competitors were signing up for our course in large numbers, emphasizing our leading position in this industry.”
