Abstract(s)
Na Universidade da Beira Interior existe uma necessidade crescente de ferramentas disponíveis para o fabrico de protótipos que são utilizados em variados projetos e trabalhos desenvolvidos. Com ênfase na construção de corpos aerodinâmicos em materiais compósitos, através de laminação em moldes, surge a falta de ferramentas e métodos de fabrico de moldes de forma rápida e barata. Uma solução passa pela criação de uma máquina de fabrico aditivo, para produzir moldes ou modelos das peças desejadas. Esta máquina será de grande volume pois as mais comuns não têm tamanho suficiente para fabricar as peças pretendidas de uma só vez. O principal objetivo deste trabalho foi o desenvolvimento e montagem de uma impressora 3D com 900 x 900 x 1000 mm3 de volume, do tipo FDM, tendo por base a história da impressão 3D e os fundamentos teóricos desta tecnologia que são apresentados. Foi tida em conta a minimização dos custos e a minimização do movimento das peças com maior massa. Esta impressora usa o chão e o teto da sala para benefício estrutural e tem uma configuração de movimento Core XY. A máquina foi desenvolvida e montada com sucesso respeitando os parâmetros iniciais e foram feitos testes de impressão que validam o seu bom funcionamento. Contudo, ainda existe margem de melhoria e de implementação de outras configurações. É também descrito um processo de moldagem que usa gesso e juta como materiais, sendo o resultado de uma das aplicações da impressora 3D desenvolvida.
At the Universidade da Beira Interior, there is a growing demand for accessible tools to facilitate the creation of prototypes for various projects. Focusing on the construction of aerodynamic bodies using composite materials through lamination on molds, a noticeable gap in tools and methodologies for efficient and costeffective production of molds is evident. One proposed solution involves designing an additive manufacturing machine dedicated to producing molds or models of the intended bodies. Characterized by its substantial volume, this machine will be capable of fabricating an entire object in a single operation. The primary objective of this undertaking was to design and construct an FDM type 3D printer with dimensions of 900 x 900 x 1000 mm3 , grounded in the historical context of 3D printing and the theoretical principles underlying this technology. Considerations for minimizing costs and reducing the movement of heavy components were incorporated into the design. This printer utilizes the floor and ceiling of the workspace for structural support and features a Core XY motion configuration. The machine was successfully designed and constructed according to the original specifications, with printing trials conducted to ascertain its operational efficacy. Nevertheless, opportunities for enhancement and integration of additional configurations remain. Furthermore, a molding process using plaster and jute as materials has also been described.
