Experimental study of digital design and digital fabrication with 3D printing of bionic cell prototype for pavilion design in the midwest region of Brazil

Abstract

The main objective of the research was to determine the possibilities and limitations of digital design and digital fabrication with 3D printing of a cell prototype. The work was structured in 3 stages: Rationale, Materials and Logistics, and Experimentation. The Rationale stage consisted of reviewing the literature on the concepts: Prototype, Bionics, Parametric Design, Digital Fabrication and 3D Printing. The Materials and Logistics stage consisted of the presentation and classification into categories of materials and the logistics that were used. The Experimentation stage consisted of 3 phases: determination of the structural characteristics of the fruit peels; determination of the shape of the cell from the structural characteristics of the fruit peels and; choice of 3D printing digital manufacturing technology. The main result of the research was that digital technologies - MEV Jeol JSM-7000F microscope, Rhinoceros 5.0 software, Grasshopper software - allow to observe and design a cell in a complex way inspired by the natural structures found in the peels of fruit species of Annona Cherimola, Mill with Annona Squamosa, L; Mauritia Flexuosa; Babassu Coconut, Soursop and Pine Cone or fruit of the Earl.
