3D printing can be used to build load-bearing concrete structures that require significantly less material and no steel reinforcement or mortar. Zaha Hadid Architects Computation and Design Group (ZHACODE) collaborated with the Block Research Group at ETH Zurich and other partners from industry to present Striatus, an arched 3D-concrete-printed masonry bridge, proposing a new language for concrete that is structurally informed, fabrication aware, ecologically responsible and precisely placed to build more with less. Millions of new buildings all over the world are being constructed with reinforced concrete, even though this type of construction generates large amounts of CO2 emissions.



3D列印可用於建造承重的混凝土結構,這種結構需要的材料明顯較少且無需鋼筋或砂漿。札哈.哈蒂建築師事務所計算與設計團隊(ZHACODE)(Zaha Hadid Architects Computation and Design Group(ZHACODE))與蘇黎世聯邦理工學院(ETH Zurich)的塊研究團隊(Block Research Group)和其他行業合作夥伴,展示了 Striatus,這是一座拱形3D混凝土列印砌體橋,為混凝土提出了一種新的語言,它在結構上知情、有製造意識、對生態負責,並且精確地以更少的錢建造更多的東西。 全世界數以百萬計的新建築都用鋼筋混凝土建造,儘管這種類型的建築會產生大量的二氧化碳排放。

The steel used for the reinforcement and the cement for the concrete are especially problematic in this regard. The 3D printed concrete bridge – named Striatus -  presents a way to reduce both. The 12-by-16-metre arched footbridge is built entirely without reinforcement, combining traditional techniques of master builders with advanced computational design, engineering and robotic manufacturing technologies. Using an additive process, the construction was built with concrete blocks that form an arch much like traditional masonry bridges. This compression-only structure allows the forces to travel to the footings, which are tied together on the ground. The dry-assembled construction is stable due to its geometry only. Because the construction does not need mortar, the blocks can be dismantled, and the bridge reassembled again at a different location. If the construction is no longer needed, the materials can simply be separated and recycled.
