Methodology evaluates additive and conventional manufacturing for obsolete parts in aggressive environments, highlighting efficiency implications.
The increasing demand for sustainable and cost-effective solutions in industrial maintenance calls for innovative approaches in reproducing obsolete spare parts, particularly in aggressive operational environments. This study presents a methodology based on virtual engineering to evaluate and compare additive and conventional manufacturing technologies for such applications. By utilizing digital tools like 3D scanning and CAD modeling, the process minimizes material waste and optimizes production energy usage. The analysis of a work wheel for an oil pump demonstrates how hybrid approaches can support environmentally conscious decision-making in spare part production. The methodology contributes to pollution control and resource efficiency in the context of legacy equipment refurbishment in heavy industries.
