Resumen
[es] En este TFG se han diseñado y fabricado microrreactores con forma monolítica y con una estructura interna de tipo espuma regular mediante la técnica de estereolitografía con resina cerámica. Se elige una estructura Gyroid por la complejidad que puede llegar a generar en el flujo de cualquier fluido que pase a través de sus cavidades. Se realiza una valoración de las propiedades físicas, se exploran las etapas de postproceso estudiando parámetros como la reducción de volumen por la merma que sufren las piezas También, se realiza un recubrimiento catalítico con un óxido metálico sobre los monolitos para analizar su capacidad de
soportar sólidos en su superficie. El principal aporte de este TFG, es haber creado un protocolo de diseño y fabricación, en el que se aportan detalles, de todas las etapas de diseño, fabricación y postproceso, que no se suelen reportar en literatura.
[en] In this TFG, microreactors with a monolithic shape and a regular foam-type internal structure have been designed and manufactured using the ceramic resin stereolithography technique. A Gyroid structure is chosen due to the complexity that it can generate in the flow of any fluid passing through its cavities. An evaluation of the physical properties is carried out, the post-processing stages are explored by studying parameters such as volume reduction due to the shrinkage suffered by the pieces. Also, a catalytic coating with a metal oxide is carried out on the monoliths to analyse their capacity to support solids on their surface. The main contribution of this TFG is creation of a design and manufacturing protocol, which provides details of all the design, manufacturing and post-processing stages, which are not usually reported in the literature.
