Appreciations towards So Concrete for providing the following description:

来自捷克的创新公司So Concrete深耕于机器人建造技术领域，他们于近期设计并实现了位于布拉格Holešovice的Výstaviště车站项目。

The innovative Czech company So Concrete, which is successfully developing the field of robotic construction technologies, designed and realized the project of the unique Výstaviště tram stop in Holešovice, Prague.

该车站的建造应用了内力分布或结构中压力和张力的自然原理，最终的设计结果不仅具有独特性，更重要的是能够最大程度地提升效率。与传统技术相比，UHPC（超高性能混凝土）3D打印技术能够节省60%的材料，并尽可能地降低人力的使用。该项目也是So Concrete公司首次进行的城市家具方面的干预实践。

The construction of the stop uses the natural principles of internal force distribution or pressures and tensions in the structure, and the resulting design is not only unique, but above all maximally efficient. Compared to conventional technologies, this approach saves up to 60% of material, and in terms of economics and sustainability, robotic 3D printing of high-performance concrete can be considered the technology of the future. This Prague tram stop, with a minimal share of human labour, is So Concrete’s first intervention in the field of urban furniture.

车站内设有长椅和信息板，使整个空间变得更具完整性，其目的是展示技术的功能特性及其在审美方面的额外价值。

A bench and information panels complete the stop. It is, therefore, a comprehensive solution for the entire space. The aim was to show the functionality of the technology and the high aesthetic added value.

该项目的位置选择也并非出于偶然：一方面，布拉格本身就是一座公共交通高度发达的现代大都市，另一方面，Stromovka公园旁的Výstaviště车站位于布拉格第七区，该区被认为是一个先进、现代且富有创造性的区域，亦是众多艺术和文化机构的所在地。

The location was not chosen by chance, Prague is a modern metropolis with highly developed public transport. The location of the Výstaviště tram stop near the Stromovka park is located in the Prague 7 district, which is perceived as a progressive, modern and creative district, home to a number of artistic and cultural institutions.

制造与材料 | Production and materials

车站由几个不同的结构部分组成，它们使用了不同类型的混凝土和3D打印方法。顶篷和长椅是用机器人3D打印技术制造，并根据功能和负载选择来选择混凝土材料，例如屋顶处使用了钢纤维进行加固，而长椅座位区并没有采用。为了制造柱头部分，先利用机器人将模具铣削和打印出来，随后再用3D打印将材料填充进去。

The stop is composed of several structural segments, for which different types of concrete and 3D printing approaches were used. The roof and the bench were manufactured using robotic 3D printing. The material – concrete – was chosen according to function and load. For example, steel-fiber reinforcement was not used for the bench seating area, as opposed to the roof, which contains this reinforcement. To produce the column heads, the robot milled and printed the moulds into which the final heads were subsequently printed.
