Diseño de una desfibradora de bambú usando software de código abierto y libre.

Abstract

For decades, bamboo has existed in the Amazonian and Coastal regions of Ecuador. With the fibers of this material, many products can be obtained, such as clothing, handicrafts, structural reinforcements, pharmaceutical materials, etc. However, bamboo has not been fully exploited due to the lack of adequate machines for minor producers to obtain the fiber. Therefore, this project shows the design of a bamboo shredder with open source software for representation and 3D modeling. The strategy that includes conceptual, materialization and detail design, in conjunction with the data provided by the International Network for Bamboo and Rattan (INBAR) and the beneficiaries, allowed the design of a machine that meets the needs of minor producers with a performance of 3 culms per hour. Initially, the user's needs were analyzed, and the geometry was generated using an open source software called "FreeCAD", so that, accompanied by the corresponding calculations and the availability of the elements in the market, the idea was transformed into an engineering reality, selecting standardized elements, obtaining construction drawings of the machine, costs, post build test protocol and maintenance suggestions. Finally, it was verified that the design fulfills its purpose with quality, providing satisfaction to the potential users and that, with a subsequent construction, it would impact the bamboo sector in Ecuador.
