Resumo
A competitividade do mercado atual requer que as empresas inovem e se reinventem continuamente, tanto no que concerne aos seus produtos quanto aos seus processos. Neste sentido, o presente trabalho visa explorar os atos inerentes à fundição e àqueles pertinentes à manufatura aditiva, buscando propor a utilização de modelos não convencionais, como a Manufatura Aditiva por Fabricação com Filamento Fundido, processo de concepção de modelos fundidos para moldagem em areia verde a partir da análise e avaliação do desgaste do material, e estimativa da quantidade de peças produzidas através da moldagem mecanizada. Para isso, foram submetidas amostras de modelos impressos em ABS juntamente com modelos de materiais convencionais,
os quais forma testados em condições reais de moldagem mecanizada, produzindo mais de 1200 moldes com medições realizadas em intervalos de aproximadamente 200 peças. Com isso, tornou-se possível verificar se um molde impresso possui a mesma resistência ao desgaste que a madeira ou alumínio.
The competitiveness of the current market requires companies to continually innovate and reinvent themselves, both with regard to their products and their processes. In this sense, the present work aims to explore the acts inherent to the foundry and those pertinent to additive manufacturing, seeking to propose the use of unconventional models, such as Additive Manufacturing by Manufacturing with Cast Filament, a process for designing cast models for molding in green sand. from the analysis and evaluation of the wear of the material, and estimation of the quantity of parts produced through mechanized molding. For this, samples of models printed in ABS were submitted together with models of conventional materials, which were tested in real mechanized molding conditions, producing more than 1200 molds with measurements carried out at intervals of approximately 200 pieces. With that, it became possible to check if a printed mold has the same wear resistance as wood or aluminum.
