ABSTRACT
The increasing demand for sustainable construction solutions necessitates a shift from conventional building materials toward biodegradable, recyclable, and reusable alternatives. This research introduces Pulpbaffle, an innovative acoustic system developed using cellulose-based composite mixtures and additive manufacturing techniques. By integrating parametric digital design with material optimization, this study explores the potential of cellulose—an abundant and biodegradable resource—to enhance acoustic performance while reducing environmental impact. The study outlines the development of corrugated geometries tailored for sound absorption, diffusion, and reflection, leveraging computational tools and genetic optimization algorithms to refine acoustic behaviour. Additionally, the research details the fabrication process, material composition, and structural performance, addressing challenges related to shrinkage and deformation during the additive manufacturing process. The results demonstrate that Pulpbaffle offers a scalable and adaptable acoustic solution that aligns with circular economy principles, presenting a viable alternative for sustainable architectural applications.
