Additive manufacturing allows the fabrication of complex geometries with enhanced performances, making it interesting for application in façade components. Assessing the performance of non-standard geometries and 3D printed parts requires a combination of digital and analytical methods to retrieve validated models which can guide the design process. In this study a 3D printed mono-material façade component was designed, where the complex geometrical configuration enhance its thermal insulation properties. For this, a digital workflow was developed, encompassing performance-driven design, performance assessment and geometry generation for fabrication.
Analytical heat transfer models, heat flux measurements, and heat transfer simulations with COMSOL Multiphysics were used to assess the thermal properties of different geometrical alternatives. By observing and comparing the results, a validated model was defined to retrieve design guidelines and thermal performance indicators. The results identify porosity as the driving factor for thermal insulation and clarify the nature of the heat transfer in 3D printed cellular structures. Open surface-based geometries were preferred for the good combination of thermal properties and manufacturability. The findings are embedded in a digital workflow in Rhino-Grasshopper, enabling the design of insulating cellular structures to be used in 3D printed façade components.
