Abstract
This study analyses the thermoplastic 3D printing feasibility of a performative large-scale facade prototype. The large-scale facade panel is a geometry informed by fabrication and environmental parameters integrated gradually in the computational design process. The computational design identifies initially the 3D printing freeform potential employed by architects and designers. Then, light distribution, an environmental performance, is integrated in the computational design, by testing daylight simulations. Next, the fabrication parameters are integrated in the computational design for achieving geometry accuracy and preventing deformations. These parameters are surface angle degree, robotic speed, material extrusion values, adhesion to print bed, and inner-layer adhesion. Four iterations of the facade prototype were manufactured from polyethylene terephthalate with large-scale robotic material extrusion. The final fabrication experiment, measuring 2000 mm x 100 mm x 2000 mm, brings conclusive remarks on the key findings of this study and design guidelines for 3D printing performative facades.
