为迎接2024年奥运会的举办，巴黎平原大公社已授予Freyssinet / Lavigne＆Cheron Architects / Quadric / XtreeE / LafargeHolcim财团设计的巴黎40米步行人行天桥，其桥面全部由3D打印制成结构混凝土。

In anticipation of the 2024 Olympic Games, Plaine Commune Grand Paris has awarded the Freyssinet / Lavigne & Cheron Architects / Quadric / XtreeE / LafargeHolcim consortium the design-build of a 40-meter pedestrian footbridge in Paris whose deck will be entirely made of 3D printed structural concrete.

该项目结合了互补的专业技术知识，为在控制成本和期限内实现复杂的建筑和结构3D打印混凝土元素以及开发定制解决方案铺平了道路。

This project, which combines complementary technical expertise, paves the way for the realization of complex architectural and structural 3D printed concrete elements and for the development of customized solutions, with controlled costs and deadlines.

对于如此大规模的第一个项目-至少就人行天桥而言-利用3D结构混凝土打印，建筑业进入了工业化4.0时代。结构的数字化设计，行人天桥组件的工业化生产及其现场快速组装带来了敏捷性和节俭：更少的运输，不需要模板，更少的材料消耗（目标是将混凝土消耗减少60％）常规结构）和建筑师更大的形式自由度。

For the first project of this magnitude – at least as far as footbridges are concerned – leveragin 3D structural concrete printing, construction enters into the era of industrialization 4.0. The digital design of the structure, the production in industrial conditions of footbridge components and their rapid assembly on-site bring agility and frugality: less transport, no need for formwork, less material consumed (target of a 60% reduction in concrete consumption compared to conventional structures) and greater freedom of form for architects.

该项目将成为一种新的基础设施类型的先驱，这种类型在法国和世界范围内可能会被拒绝使用，并进一步验证XtreeE开发的3D打印技术。

This project will be the forerunner of a new infrastructure typology, which can be declined in France and around the world, and further validates the 3D printing technology developed by XtreeE.

XTreeE成立于2010年代，起源于一个名为DEMOCRITE的研究项目，该项目位于巴黎-马拉夸建筑学院，巴黎艺术与美工学院，法国国立艺术与音乐学院，INRIA索菲亚·安提波利斯和法国国立高级雕塑学院之间Industrielle-Les工作室。该公司由工程师，架构师，自动化专家和程序员组成，他们对建筑的未来和连接的3D打印单元的全球网络抱有共同的愿景。

Founded in the 2010s, XTreeE sprouted from a research project, named DEMOCRITE, between the Paris-Malaquais School of Architecture, the Arts et Métiers ParisTech engineering school, the Conservatoire National des Arts et Métiers, INRIA Sophia Antipolis and the École Nationale Supérieure de Création Industrielle-Les Ateliers. The company is made of engineers, architects, automation specialists and programmers who share a common vision of the future of construction and a worldwide network of connected 3D printing units.

该公司的研发和原型制作中心位于大巴黎的集群Rungis。该系统目前与合作伙伴Concreative一起在巴黎高等巴黎理工学院（法国马恩拉瓦莱）和迪拜（阿拉伯联合酋长国）运行。 2020年底，将在日本和美国启动另外两个3D打印部门。

The firm’s R&D and prototyping centre is located at Rungis, a cluster in Grand Paris. It systems are currently operational at Ecole des Ponts ParisTech (Marne la Vallée, France) and in Dubai (United Arab Emirates), together with partner Concreative. Two other 3D printing units will be launched at the end of 2020 in Japan and the United States.
