German construction firmPERI Grouphas revealed that it’s using 3D printing to renovate an existing building for the very first time.
仙女描述s a “world’s first,” its engineers are deploying aCOBOD3D printer to add an entirely new floor to a family home in the Bavarian town of Lindau. According to Dr. Fabian Meyer-Broetz, head of the firm’s construction 3D printing division, the project will see it break new ground, while exhibiting the technology’s potential for addressing applications other than erecting buildings from scratch.
“Once again, we are entering new territory here with our construction 3D printing technology,” explained Meyer-Broetz. “Technologically, the setup of the printer in particular has been a new challenge due to the slope of the site. The project in Lindau shows once again how flexible and versatile this new technology is.”
PERI’s next-level renovation
Designed by fellow German construction firmBodensee Architektur, PERI’s home extension is being carried out alongsideBALDAUF GEBÄUDEDRUCK, on the house of its owner André Baldauf. Already, the companies’ engineers have removed the building’s old roof and laid down a concrete ceiling, providing the basis for a new 3D printed floor.
一旦完成，该扩展程序将测量约120平方米，并达到3.7米的高度，但是根据Baldauf的说法，该项目的独特施工方法本身可以代表一个突破。“我们时代最重要的主题是仔细地使用我们的地球和所有领域的数字化。到目前为止，建筑行业对此有很少的答案。”巴尔多夫说。
“[By] mixing highly CO2-binding neptune grass insulation, a folding wooden roof and a 3D printed load-bearing structure, we have been able to construct the building extension in a nearly CO2-neutral way,” he added. “The walls were planned and printed in 3D, and the wooden roof was tied down ready for assembly according to 3D plans. That’s how we plan and build today.”
In practise, PERI is constructing its extension usingHeidelbergCement’s“ I.Tech 3D”材料，是用于3D打印的定制的，以及Cobod的BOD2machine. During the build so far, the system has reportedly shown the flexibility to print on uneven surfaces in existing structures, effectively proving it’s capable of creating more than just standalone buildings.
Unleashing the BOD2
PERI’s Bavarian renovation project marks the latest in a string of collaborations with COBOD, a company in which it has been a shareholder since 2018. Over the last three years, the BOD2 has consistently proven itself to be a highly-adept house building tool, particularly given that it’s able to move into any position across three axes, without needing recalibration.
With a print speed of 1 m/s, the BOD2 is also one of the fastest construction 3D printers on the market, and it’s reportedly capable of creating 1 m2每五分钟的双皮墙墙，而其安全认证使工程师可以完成手动任务，例如周围的管道，加快房屋建筑过程。
Earlier this year, PERI finished using the BOD2 to 3D print athree-storey apartment building在德国瓦伦豪森（Wallenhausen），现在预计将在那里的国内市场出租。但是，COBOD的技术并未仅由其零件所有者部署，而是它继续在全球建设项目中广泛使用。
美国非营利组织Habitat for Humanityis currently utilizing the BOD2 to3D打印负担得起的住房它自己在亚利桑那州的坦佩（Tempe），它打算授予有需要的家庭。同时，在马拉维的一个类似慈善项目中14Treeshas opted to leverage COBOD’s technology to build a3D printed school, doing so inside 18 hours, before opening it to students.
除了住房外，BOD2还发现了过去的能源应用，Corbod，GE可再生能源andLafargeHolcimworking to3D打印“唱片 - 塔”涡轮塔去年。该项目的建立旨在提高可再生能源生产并降低其级别的成本，同时展示BOD2的功能，Lafargeholcim表示“扩大了建筑可能性的领域”。
Advances in 3D printed homes
Although COBOD has managed to establish itself as one of the leaders in the emerging construction 3D printing sector, it’s now beginning to face some stiff competition.ICON也已成为该行业的早期跑步者之一，它部署了其Vulcan 3D打印技术来构建four multi-storey housesin East Austin earlier this year.
Likewise,强大的建筑物现在有了筹集了超过1亿美元to fund the continued roll-out of its proprietary extrusion-based construction technology. In March 2021, the firm unveiled plans of its own to3D print a fifteen-strong neighborhood科切拉谷地附近的房屋,它的目标是list on the U.S. market for between $595,000 and $950,000 each.
在更实验的层面上，公司喜欢WASP还在开发基于生物材料的建筑方法，可以构成新的环保房屋建筑模型的基础。意大利3D打印机制造商完成了建筑有机“ tecla”房屋from clay in January, although it hasn’t yet been opened to members of the public.
