Abstract To find a low-cost and flexibly adaptive building design and construction method in the field of sustainable architecture, the authors attempted to propose a user-fabricable 3D-printed kinetic shading device that is selectively actuatable by a switch between a geared DC motor and a thermomechanical shape memory alloy (SMA) actuator. This approach leverages additive manufacturing, SMA, and origami to suggest a lightweight, motorless, and silently operable kinetic building module with compact actuation parts. User-customization is prioritized in its manufacturing, installation, and operation: the device is made by 3D-printed thermoplastic components and is self-supportively installable. User-engaged operation is considered by involving an app-based remote control, along with sensor-integrated automation. The results of responsive building performance simulation and mockup tests demonstrate that the thermo-responsive building module enables control of solar radiation and light, reducing room temperature dynamically. The study findings speak to the limitations and potential of material-based actuation for adaptive building technologies.

具有交替驱动的 3D 打印可连接动力遮阳装置：使用形状记忆合金 (SMA) 实现气候自适应响应架构

摘要 为了在可持续建筑领域找到一种低成本、灵活适应性的建筑设计和施工方法，作者试图提出一种用户可制造的 3D 打印动态遮阳装置，该装置可通过齿轮直流电机和热机械形状记忆合金 (SMA) 致动器。这种方法利用增材制造、SMA 和折纸来提出一种轻巧、无电机且可静音操作的动力学构建模块，具有紧凑的驱动部件。在其制造、安装和操作中优先考虑用户定制：该设备由 3D 打印的热塑性组件制成，可自行安装。通过涉及基于应用程序的远程控制以及传感器集成自动化来考虑用户参与的操作。响应式建筑性能模拟和模型测试的结果表明，热响应式建筑模块能够控制太阳辐射和光线，动态降低室温。研究结果说明了基于材料的驱动对自适应建筑技术的局限性和潜力。
