Existem bastantes trabalhos que poderão ser desenvolvidos a partir da presente dissertação. Dado que o forno de vazamentos foi uma das principais limitações no desenvolvimento do trabalho experimental, seria interessante o projeto e desenvolvimento de um forno de com maior capacidade e fiabilidade superior. Um dos pontos de melhoramento poderá residir na criação de um sistema de suporte para carapaças cerâmicas no interior do forno, pois o método atual poderá ser pouco preciso e seguro, uma vez que a carapaça é simplesmente apoiada em tijolos.
A análise dos defeitos e conformidade com as normas poderá ser outro trabalho futuro, sendo a presente dissertação um bom ponto de partida.
O estudo da variação dimensional ao longo de todo o processo de fundição por cera perdida é interessante para que se possa caracterizar o modo como cada fase influencia as variações dimensionais do produto.
Na presente dissertação, não foi explorada a possibilidade de reparação por soldadura de peças fundidas. Esta é uma área interessante para o desenvolvimento de futuros trabalhos.
