佩里建造德国的第一座“现成市场就绪” 3D印刷住宅大楼

Germany-based construction companyPERI Groupis in the process of erecting the country’s first “market-ready” additive manufactured residential building.

佩里(Peri)的两层楼房屋位于北莱茵 - 韦斯特法里亚(North Rhine-Westphalia)的贝克姆(Beckum),正在使用丹麦制造公司建造cobod’s3D打印技术。该项目是该地区更广泛的“创新鲍恩”或“创新建筑”计划的一部分,据报道,该项目代表了德国制造技术的第一次。

“我们非常有信心,在未来几年中,建筑印刷在某些市场领域将变得越来越重要,” Peri的创新与市场总监Thomas Imbacher说。“我们为佩里参与该项目的参与使我们成为这种新建筑技术的先驱和先驱。”

“ Beckum的3D印刷住宅建筑的建设是3D建筑印刷技术的里程碑。”

PERI and COBOD’s construction expertise

Peri于1969年成立于1969年,总部位于德国的Weißenhorn,是模板和脚手架系统以及土木工程解决方案的全球供应商。这家家族拥有的公司在世界各地拥有60多家子公司,通过该公司为各种建筑项目提供了支持,从办公大楼到石油钻机。

In recent years, PERI has developed an interest in 3D printing, and it acquired a minority stake in COBOD in 2018. The company’s decision to invest in the Danish construction firm is significant, because its concrete fabrication technology has previously been deployed in the fabrication of numerous large-scale buildings.

在今年Bautec建筑展览for instance, COBOD provided a live demonstration of its machines by3D printing the walls of four small houses。Belgian sustainable building companyKamp Cmeanwhile, has leveraged the company’s BOD2 system to build atwo-floor, 90 square meter house

Among a variety of other projects, COBOD’s technology is also being used as part of a program withGE可再生能源, to 3D print“record-tall” turbine structures用于生成清洁电源。现在,Peri本身正在加入该法案,并在与公司的合作伙伴关系中构建了许多建筑物中的第一个建筑物中的第一座建筑物中的第一个。

“At PERI, we see ourselves as a leading innovator in our markets,” said Dr Fabian Kracht, Finance & Organisation Director at PERI. “Investing wisely in start-ups that are offering new solutions in our markets is another aspect of that. The success story in Beckum is validation that we have taken the right approach.”

PERI’s Bavarian 3D printed building

Given that the project represents the first time COBOD’s technology has been deployed in Germany, PERI has had to spend months gaining approval for the process. The concept’s application was supported by national engineering officeSchießlGehlenSodeikat, and the plans were tested and eventually approved at the慕尼黑技术大学

Having got the go-ahead from state regulators, PERI began the construction process using a rapid BOD2 system, which moves at a speed of 1 m/s, and only takes five minutes to print 1m² of a double-skin wall. The advanced construction process has allowed the building’s architects, MENSE-KORTE, to create a complex building design, without raising its overall cost.

“The concrete printing process affords us designers a high degree of freedom when we are designing buildings,” said Waldemar Korte, architect and partner at MENSE-KORTE. “With conventional construction methods, this would only be possible at great financial cost.”

“With our printed residential building in Beckum, we are demonstrating the potential of the construction printing process.”

在仙女的设置,BOD2打印机安装to a gantry, meaning that its print head moves about three axes on a securely installed metal frame. The benefit of this approach, is that the machine can move along to any position within the site, and only needs to be calibrated once which reduces any potential downtime.

该系统还经过认证,可以在打印过程中在建筑区域内进行工作,这允许在不中断的情况下安装管道和其他零件。一旦完成,家庭房将有两层楼,一个宽敞的160m2living area, but according to PERI, the process can still be optimized further, for use within future building projects.

“As this is the first building of its kind, we are making a point of printing at a slower rate than what is actually possible,” said Leonhard Braig, Production & Supply Chain Director at PERI. “We want to take the opportunity to gain further experience in day-to-day operations, as this will help us to leverage the cost reduction potential of our technology to a greater extent in the next project.”

Additive manufacturing and affordable housing

In recent years, a number of companies have sought to leverage the cost benefits of 3D printing to produce more affordable homes for people to live in.

Established 3D printing manufacturing firm图标for instance, deployed its Vulcan system to完全捏造房屋in Austin, Texas, that reportedly cost less than $4,000 to build. The 350-square-foot home was created in just 48 hours as a proof of concept for the firm’s technology.

建造Mighty Buildingshas managed to raise $30 million in funding to develop its advanced additive construction technique. Using the investment, the firm has now launched as a fully-fledged ‘production-as-a-service’ business, offering a range of 3D printed350-square-foot housing modules

在其他地方,具体专家QUIKRETEand轮廓制作公司,已经合作3D print residential, commercial and industrial buildingsaround the United States. The two companies aim to build housing for people on lower incomes or those needing disaster relief facilities.
