Architectural Production Using 3D Printing with Algae-Bioplastic Compounds

Growing awareness of the climate crisis, driven by carbon pollution and material overconsumption in construction, has sparked interest in sustainable building materials. This has led to research on materials that support carbon circulation, with a particular focus on algae, a natural and renewable resource. This study examines the architectural application of algae-based bioplastics by analyzing precedent cases where algae has been used as a biomaterial alongside additive manufacturing techniques. The research specifically explores Fused Granular Fabrication (FGF), a 3D printing method suitable for producing algae-based bioplastics at an architectural scale. By experimenting with various types of bioplastics derived from waste algae, the study assesses the feasibility of creating architectural elements such as columns, parametric curved surfaces, and mesh structures. The findings highlighted the potential of digital fabrication methods using algae-based bioplastics and proposed three specific manufacturing techniques: Planar 3D Printing, Non-planar 3D Printing, and 3D Printed Formwork.
