Aplicação da manufatura aditiva no setor de fundição: análise comparativa de custos e eficiência entre processos

Abstract

This study aims to analyze the application of additive manufacturing in the foundry sector by comparing its costs and efficiency with those of the conventional process of producing wooden casting patterns. Additive manufacturing, represented by 3D printing, has emerged as a promising alternative for optimizing industrial production by reducing waste and increasing the precision of manufactured components. For this analysis, a casting pattern was produced in PETG using 3D printing, and another was made using traditional wooden methods. The study evaluated production time, associated costs, and the final quality of the parts. The results showed that additive manufacturing offers significant advantages, with a manufacturing time of approximately 17.57 hours, compared to around six days for the wooden model. Additionally, the costs of the additive process were approximately 89.41% lower than those of the traditional method, demonstrating the economic viability of this technology. The PETG model also showed greater durability, allowing more usage cycles without compromising the quality of the final part. Thus, the study reinforces the potential of additive manufacturing as an efficient and innovative solution for the foundry industry and highlights the need for further research to enhance its applications.
