3D 打印结构楼面系统 A structural 3D-Printed Floor

3D 打印技术的发展降低了复杂结构或单元装配体系的制造成本，使其更富竞争力。精心设计低应力受压形状解放了建筑形态，让数字化制造工艺得到了最大程度的利用。正如瑞士工程师Robert Maillart先锋性的三铰拱混凝土桥一般，the Armadillo Vault这个利用了3D 打印技术的复杂几何结构形态也经过了大量的数学分析，以保证压力传导在各种受力情况下的稳定度。这些创新性的预置组件将对传统封闭空间的建造方式掀起一轮新的挑战。

New developments in 3D printing enable the fabrication of complex structures and components at a competitive cost. With well-designed compression shapes that have low stresses, the formal freedom offered by such exciting digital fabrication technologies can be fully exploited. Like Swiss engineer Robert Maillart’s pioneering, three-hinged concrete bridges, the elements of this 3D-printed and geo- metrically intricate structure have been mathematically analysed to control the compressive force flow for all loading cases. Such prefabricated components are opening new possibilities in the challenge to enclose space.
