Disseny i fabricació de motlles per a materials compostos mitjançant fabricació additiva

Abstract

Aquest projecte sorgeix amb l'objectiu d'apropar els materials compostos a un públic general. Aquesta família de materials és molt interessant a causa de les seves altes propietats específiques, elèctriques i tèrmiques. La gran innovació que presenten, però, té l'inconvenient d'encara un elevat cost econòmic. Partint d'aquest impediment, i amb la finalitat anterior, es proposa baixar el cost atribuït al disseny i fabricació dels motlles. Aquest cost és gran ja que tradicionalment s'han fabricat mitjançant mecanitzat. Aquesta tecnologia, tot i haver-se demostrat molt efectiva per a aquesta tasca, requereix un procés de disseny i maquinària cars. Així doncs, per a baixar el cost, es planteja una altra tecnologia de fabricació, la fabricació additiva mitjançant impressió 3D. El treball consisteix a documentar tot el procés d'implementació de la impressió 3D en la fabricació dels motlles per a tal que el lector el pugui repetir el procés i aconseguir motlles en un procés més econòmic i ràpid. Els resultats obtinguts permeten afirmar que si és possible fabricar materials compostos amb motlles d'impressió 3D.

Este proyecto nace con el objetivo de acercar los materiales compuestos a un público general. Esta familia de materiales, es muy interesante gracias a sus altas propiedades específicas, eléctricas y térmicas. La gran innovación que presentan, tiene el inconveniente de aún un elevado coste económico. Partiendo de este impedimento, en conjunto con el objetivo anterior, se propone bajar el coste asociado al diseño y fabricación de los moldes. Este coste es grande ya que tradicionalmente, se han fabricado mediante tecnologías de mecanizado. Estas, aunque muy efectivas para esta tarea, requieren de un proceso de diseño y maquinaria caros. Así pues, para bajar el coste, se plantea usar otra tecnología de fabricación, la fabricación aditiva mediante impresión 3D. El trabajo consiste a documentar todo el proceso de implementación de la impresión 3D en la fabricación de los moldes para que el lector pueda repetir el proceso y conseguir moldes más económicos y rápidamente. Los resultados obtenidos permiten afirmar que si es posible fabricar materiales compuestos con moldes de impresión 3D.

This project was born with the aim of bringing composite materials to a general public. This family of materials is very interesting thanks to its high specific properties, electrical and thermal. The great innovation they present, has the disadvantage of still a high economic cost. Based on this impediment, in conjunction with the previous objective, it is proposed to lower the cost associated with the design and manufacture of molds. This cost is great. Traditionally, they have been manufactured using machining technologies. These, although very effective for this task, require an expensive design process and machinery. So, to lower the cost, it is proposed to use another manufacturing technology, additive manufacturing using 3D printing. The project consists of documenting the entire process of implementing 3D printing in the manufacture of molds so that the reader can repeat the process and get molds more economically and quickly. The results obtained allow us to affirm that it is possible to manufacture composite materials with 3D printing molds.
