FABRICACIÓN ADITIVA DE GRAN FORMATO PARA LA INDUSTRIA NAVAL. TECNOLOGÍAS EXISTENTES Y METODOLOGÍA DE DISEÑO ADAPTADA.

Abstract

This work presents an overview of latest trends and technologies of additive manufacturing or 3D printing with an operative printing volume over 1 cubic meter. From prototyping technologies using materials such as clay, metal and plastics, to fully functional printers focused in plastic parts. A product design step by step methodology is introduced starting from analysis of the state of art to a product concept. This is developed combining CAE tools and is adapted to the requirements of big size 3D printing technologies. The study case consists in the design and development of several plastic parts for the naval industry with big size additive manufacturing technologies. We show an iterative design process combining CAE, CAD modeling, FEA simulation, topology optimization and materials developments, leading to a fully optimized part ready to be printed in the aforementioned technologies. This work is framed within “3DCABINS Project. Development of material and additive manufacturing technology for the production of living quarters in the naval sector”, with INNANOMAT research group and NAVANTIA company as participants. This project is supported by the programme “I Convocatoria de Proyectos de Innovación Empresarial con Proyección Territorial” managed by CEIMAR.
