Additive manufacturing (AM) is revolutionizing product development by producing complex 3D objects directly. AM supports energy efficiency during manufacturing by speeding up the whole product development process, reduction in process and resource usage, and a vast range of different parts with different characteristics by supporting multi-material usage. Accordingly, AM is a sustainable manufacturing technology than current manufacturing technologies. Through these advantages of AM, most research has focused on how to fabricate products with complex structures like lattice and honeycomb structures without considering product lifecycle in product development. Therefore, this study proposes a modular design method to enhance a product recovery strategy using AM technologies. The objective of this paper is to identify modules that are fabricated by AM based on minimizing the disassembly complexity of products. In order to quantify the disassembly complexity at the end-of-life stage, the disassembly complexity of products (PDC) is assessed by considering the number of components and interfaces, and design complexity of the components and interfaces. The PDC is modified to single component complexity index (SCCI) with component and interface complexities simultaneously in this study. Based on the SCCI, a module is identified by consolidating components with high complexity, and can be fabricated by AM. The module contributes to improving product recovery processes by reducing the disassembly complexity. A case study is used to demonstrate the usefulness of the proposed method by comparing disassembly complexities.
