Abstract
Despite recent advances in additive manufacturing technologies, challenges remain to build 3D-printed structures at the architectural scale due to the high cost of large printing equipment. To address this challenge, modular construction has demonstrated its merit by making smaller prefabricated components and using on-site assembly. This paper presents a case study of a 3D-printed hypar shell structural art using modular construction. Guided by parametric design and structural analysis, we optimized the hypar shell to form a butterfly-like shape with a hollow-out pattern. The prefabrication of modular units was completed using commercial 3D printers to catch a limited production time. The prefabricated modular unit of the hypar shell was assembled on site for the Guangzhou International Light Festival, in which the lighting effect was added through the adjustable transparency of hollow spaces within the sandwiched panels. The 3D-printed hypar shell was also disassembled and rebuilt in the UK, showcasing the adaptability and flexibility of the modular design. The resulting 3D-printed structural art not only provides unique aesthetics for the built environment but also demonstrates the possibility of building large shell structures with a low budget by reducing complex falsework.
尽管增材制造技术取得了最新进展,但由于大型打印设备成本高昂,在建筑规模上建造 3D 打印结构仍面临挑战。为了应对这一挑战,模块化建筑通过制造较小的预制构件和使用现场组装的方式证明了其优点。本文介绍了一个采用模块化结构的 3D 打印 hypar 外壳结构艺术的案例研究。在参数化设计和结构分析的指导下,我们对 hypar 外壳进行了优化,使其形成具有镂空图案的蝴蝶状外形。在有限的生产时间内,我们使用商用三维打印机完成了模块单元的预制。hypar 外壳的预制模块单元在广州国际灯光节现场进行了组装,通过调节夹层板内中空空间的透明度来增加灯光效果。3D 打印的 hypar 外壳还在英国进行了拆卸和重建,展示了模块化设计的适应性和灵活性。由此产生的 3D 打印结构艺术不仅为建筑环境提供了独特的美感,还展示了通过减少复杂的虚假工程,以较低预算建造大型外壳结构的可能性。
