The project proposes a study on the construction potential in civil engineering and architecture by combining additive manufacturing technology and viscous materials. The research will be carried out on both the direct extrusion of viscous doughs using large-scale printing equipment and the indirect use of additive manufacturing, as Fused Deposition Modeling, to produce casting moulds for viscous doughs. Its primary aim is to demonstrate how digital fabrication, and especially additive manufacturing, can be used to create innovative building elements and systems with a dual purpose:
The research will be developed simultaneously in four different areas:
The research activities will be finalized through the implementation of two experimental pilot sites. These will be developed to address the following challenges:
Drafting of a technical review on the use of viscous materials in additive manufacturing; investigating the most current state of the art both on the “material” and “manufacturing process” sides; addressing the most critical challenges related to the structural use of digital manufactured elements. The sectors involved are civil engineering and architecture.
Definition of optimized mixtures of natural and waste materials with the implementation of chemical components and physical-mechanical actions that improve the specific required fresh-state properties and hardened-state technical performance and quality of both material and manufactured elements.
Definition of technical production systems in additive manufacturing through the integrated use of differentiated handling systems and differentiated extrusion systems
Definition of innovative architectural composition processes that integrate computational and generative design with digital fabrication techniques in viscous additive manufacturing.
Study by Life Cycle Assessment (LCA) approach (SimaPro software) the environmental impact (in terms of carbon footprint and energy demand) of both the developed mixtures and the implemented additive manufacturing process. This phase will aim to enhance the “green” aspect of the project regarding the integration of waste materials in the production of printable mixtures as well as to provide a useful tool for optimizing the additive manufacturing process in terms of energy consumption and material usage.
Proposal of a technical procedure enabling the design of structural building components by adopting the materials and technologies developed in the project.
Based on the developed mixtures/processes, proposal of an indicator for comparing materials that have differing constituents, processing requirements, environmental impacts, and technological properties with the aim of achieving an optimization in terms of performance and environmental impact.
Implementation of the pilot site for direct extrusion of viscous mixtures.
Implementation of the pilot site for the indirect use of additive manufacturing in viscous construction.
