3D printing technology is being deployed at scale to build affordable and low-carbon housing and schools in Africa, in a bid to tackle the region’s chronic infrastructure shortage.
14Treesis a joint venture between building materials specialistLafargeholcim和CDC组，英国的公共影响力投资者，该投资者使用3D打印技术最初在马拉维创建负担得起的可持续建筑，将来将把项目扩展到肯尼亚和津巴布韦。
“我对我们的合资14trees的工作感到非常兴奋，从3D印刷技术创新，从房屋到学校，加速负担得起且可持续的建筑，”中东地区负责人Miljan Gutovic说。
“This is a great example of our commitment to build for people and the planet. Starting in Malawi, we will deploy this technology across the broader region with projects already in the pipeline in Kenya and Zimbabwe.”
The 14Trees project
使用Lafargeholcim的专有墨水部署的14TREES部署的3D打印技术首次在学校开创，并有望大大减少马拉维建筑房屋和学校的时间和成本。根据联合国儿童基金会, there is a current shortage of some 36,000 classrooms in the country which would take 70 years to build using conventional methods. 14Trees believes this could be achieved within a decade using 3D printing.
The first prototype house was built in Lilongwe, of which the walls were printed in just 12 hours. Meanwhile in Salima, the walls of 14Trees’ first school were printed in 18 hours. Using traditional methods, these buildings would have taken several days to complete.
In addition to speeding up the construction process of new buildings, 14Trees’ 3D printing technology also reduces the carbon footprint for building new homes by up to 70 percent through optimized material use. In addition, the joint venture aims to create skilled local jobs with the hiring of local 3D machine operators, material specialists, builders, carpenters, roofers, and painters.
非洲CDC非洲董事总经理Tenbite Ermias表示：“ 14trees世界一流的尖端技术的推出将对马拉维和更广泛的地区产生巨大的发展影响。”“这是我们如何投资于可以支持联合国可持续发展目标的企业的一个奇妙例子。”
3D打印建筑物
3D印刷建筑物的速度，可持续性和成本收益越来越多地在建筑业内杠杆化，以生产负担得起的住房和基础设施。
One of the firms at the forefront of printing sustainable buildings is Italian 3D printer manufacturer黄蜂, which has taken part in a number of projects in this area. In 2018, the起重机黄蜂3D打印机被用来生产一栋小建筑物Shamballa的技术村，命名盖亚, and a year later embarked upon printing ahousing model called TECLA这是基于圆形制造工艺，利用可重复使用的可回收材料从当地地形采购的材料。
Elsewhere, Dutch concrete 3D printing firmCYBE构造was chosen for the房屋的3D打印in the United Arab Emirates (UAE), 3D construction startupMighty Buildingsraised $30 million to launch as a fully-fledged“生产与服务”业务和美国混凝土专家Quikrete和轮廓制作公司合作建造住宅，商业，工业和政府大楼整个美国。
最近，德国建筑公司小组commenced work on the construction of a “world first”三层印刷商业公寓楼使用丹麦制造公司的瓦伦豪森现场柯博德3D打印技术。这一消息是在佩里宣布正在建造德国第一个“市场准备就绪”的几个月之后。3D printed residential building。
