COBOD’s 3D printers forge ahead with massive construction projects – 3DPrint.com

Following a wave of investments from PERI Group, GE Renewable Energyand Cemex Ventures, COBOD prepares projects to set the tone for the future of 3D printing. In North America, material from the Danish concrete 3D printer manufacturer is being used to build a 4,000 square foot house and a two-story apartment building. Meanwhile, Central America will see the installation of the first COBOD 3D construction printer in Guatemala to help address the region’s massive housing deficit.

In Houston, Texas, German construction company PERI Group, a local construction company CIVEand HANNAH architects are constructing a two-story building that is also the largest 3D-printed residential construction to date in the United States Relying on COBOD’s BOD2 3D construction printer for the 4,000 square foot project the team succeeded in combining 3D printing in concrete with a wooden frame. This hybrid construction approach makes strategic use of both material systems and aims to increase the applicability of 3D printing in the United States, where framing is one of the most common construction techniques.

According to the company, the design of the building is conceptualized as a series of printed cores that contain functional spaces and stairs. Spatial cores are connected by a timber frame to produce an architectural alternation of concrete and framed interiors. Additionally, the project’s scalable design and construction process serves multi-family housing and mixed-use construction.

Described by HANNAH co-founders Leslie Lok and Sasa Zivkovic as a “structurally efficient, easily repeatable and materially responsive building system”, this project is the largest printed with BOD2 3D printers to date.

Fabian Meyer-Broetz, CEO of PERI 3D Construction, said: “We are confident that it will set new standards from a print design and execution perspective and underscores our role as a forerunner of this new construction techniques.

Home to a growing number of 3D printed structures, Texas has seen its share of firsts in 3D construction in recent years. In 2021, the Dallas startup Von Perry began 3D-printing the structure of custom homes in North Texas using hardware from the Minnesota-based company Custom Total. Now that his first proof of concept is nearing completion, he’s gearing up to launch his $2 million fundraising effort on the crowdfunding platform. Start the engine. Additionally, in October 2021, a Texas 3D printing construction company ICON announced it was building the largest 3D-printed home community in Austin after listing its first 3D-printed homes on the US housing market earlier that year.

BOD2: A Star is Born

A second 3D construction project in North America is announced by a local construction company nidus3D and is among the region’s first multi-story 3D printed buildings. Built in Ontario, the 2,300 square foot building also used COBOD’s BOD2 printer and a low-cost local hardware solution called D.Fab, developed in conjunction with Cemex.

Complete with a studio on the first floor and a residential area above, the construction has a 3D printed horizontal beam printed in place and lifted by a crane. It was built in just 80 hours, compared to the 200 hours it took nidus3D to erect its first building. The short construction time and inexpensive materials used to build the structure could eventually fill the housing gap in Canada. In fact, 3D-printed homes are expected to be available by summer 2022 for individuals and couples looking for affordable housing.

The Canada Mortgage and Housing Corporation (CMHC) determined that the country will need more than 22 million homes to achieve housing affordability for all Canadians by 2030. COBOD and nidus3D believe this new construction method will be a game changer in the face of the housing crisis.

“We have a severe shortage of skilled labor and a massive and growing demand for housing across Canada,” suggested nidus3D co-founder Ian Arthur. “So if we don’t start looking for new ways to build, we’re never going to catch up. It is part of our core values ​​to seek solutions to solve the housing crisis and to help build affordable housing using 3D printing.

The housing crisis in Latin America attracts the attention of COBOD.

Latin America has suffered from a housing crisis since the 1940s. Lack of adequate housing is a significant problem in developing countries, and Central and South America have had their share of housing problems . Roughly 117 million people in Latin America live in slums, so historically. Unfortunately, housing policy in the region has not been a huge success. Perhaps 3D printing can play a central role as part of the solution. That’s what Cementos Progreso is considering. As Guatemala’s largest cement company, Cementos is now spearheading the use of COBOD’s 3D construction printers in Latin America to solve the housing deficit.

Latin America has lagged behind in using 3D building printing technology to try to address the region’s massive housing deficit. Today, Cementos Progreso confirmed its commitment to 3D construction with the official inauguration of the new Innovation and Development Center in Guatemala aimed at developing the construction printing industry in the region. Additionally, the company installed Guatemala’s first COBOD 3D construction printer, a BOD2, at the R&D site, paving the way for the application of new construction technologies in the region. For months, the R&D team of Cementos Progreso has been working on the 3D modeling of urban and residential projects that it plans to manufacture with COBOD’s construction 3D printer.

For example, industrial designer Manuel Ovalle is currently at Cementos Progreso’s R&D site and has detailed some of his work on social media: “I implement design as a vital tool for testing physical and mechanical properties on site of the 3D printable material with the printed parts, aiming to develop locally available high quality digital manufacturable concrete with full characterization. I also imagined printable elements that could transform cities into more human-friendly and sustainable systems.

With so many announcements in just one week, it’s clear that COBOD is gaining momentum in the growing 3D printing construction market, which is expected to reach over $4 billion by 2030. Although the company does not disclose its revenues in its annual accounts, it did reveal that its gross profit had fallen from 4.9 million Danish kroner (DKK) (about $660,000) to 9.3 million Danish kroner ($1.3 million) between 2019 and 2020. The accounts also show that the company’s order intake for the first months of 2021 exceeded total order intake for 2020. COBOD printers change the way housing structures are built and are paving the way for more affordable housing everywhere, primarily due to the inherent technologies for faster building ability.
