The manufacturing of large scale structures with Additive Manufacturing (AM) represents one of the main challenges facing the construction industry today. The first recent large-scale realizations with the Wire-And-Arc Additive Manufacturing (WAAM) technology have shown the potential of WAAM in changing the way steel structures are currently designed and manufactured. However, despite these pioneering applications, the full comprehension of synergies and possibilities of WAAM in terms of architectural shapes, structural behavior and material response are far from being completely exploited.

In this article, the overarching design process from concept to fabrication of a half-scaled diagrid column 3D printed with WAAM technology is illustrated. The research methodology is based on a computational workflow integrating various aspects such as material properties, manufacturing features and global architectural design. The final designed WAAM-produced diagrid column has been exposed at “The Big 5 - International Building and Construction” show, held in Dubai from November 25th till November 28th 2018.

用增材制造（AM）制造大型结构是当今建筑业面临的主要挑战之一。线和弧增材制造（WAAM）技术最近的首次大规模实现表明，WAAM在改变当前钢结构设计和制造方式方面的潜力。然而，尽管有这些开创性的应用，但在建筑形状，结构行为和材料响应方面，完全了解WAAM的协同作用和可能性还远远没有得到充分利用。

在本文中，说明了从概念到用WAAM技术打印的半比例斜交柱3D的总体设计过程。该研究方法基于一种集成了各个方面（例如材料属性，制造特征和整体建筑设计）的计算工作流程。最终设计的WAAM生产的斜交柱已在2018年11月25日至11月28日在迪拜举行的“国际五大建筑-国际建筑”中展出。
