Application of the Tensegrity system to create the 3D Impression of the Butterfly Body Heliconius Doris Obscurus as a Floating Compression Structure

Dina Rochman, América Sánchez, Universidad Autónoma Metropolitana, Cuajimalpa

Abstract. In this paper we present the research carried out at the Metropolitan Autonomous University of Cuajimalpa Mexico, which consists of developing a floating structure of the body of the Heliconius Doris obscurus, worldwide knows as Laparus Doris obscurus, based on the invention of Karl Ioganson “The Tensegrity”. In this project, we made three prototypes to study the way can be performed the structure of floating compression of the butterfly body. The first prototype is a solid and performed in the 3D printer. This prototype we used it to analyze the curvature of the butterfly body. In the second and third prototype, we divide the butterfly body in 24 parts. To tension and join each of the parts, in the second prototype we use a three-dimensional network of nylon monofilament, and plastic straws as separators between each part. In each part, of the third prototype two holes opened to place two cylinders with four holes; between each part one cylinder with eight holes added, in order to pass the nylon monofilament to stress the body. The objective of this project is that students studying the design career use the techniques of geometric morphometrics, descriptive geometry and tensegrity for their terminal projects.

Keywords. Tensegrity, Butterfly, Rapid Prototyping
