ABSTRACT In process industries, the failure of a single component can lead to unexpected system shutdowns. This risk becomes even greater in aging plants, where original spare parts may no longer be available. As a result, spare parts management plays a crucial role in maintaining reliability and continuous operation. Reverse engineering (RE) combined with additive manufacturing (AM) offers a solution to this challenge. This approach shortens delivery times, reduces dependency on conventional supply chains, and supports the functional restoration of critical equipment. The aim of this study is to present a process chain for spare parts reproduction in the process industry that integrates RE and AM. Emphasis is placed on meeting established quality assurance and quality control requirements. A water pump impeller is used as a representative case study to demonstrate the proposed approach and its practical applicability.
