Design for additive manufacturing (DFAM) provides design freedom creating complex geometries and guides designers to ensure the manufacturability of parts fabricated using (AM) processes. However, there is a lack formalized DFAM knowledge that information on how plan AM processes achieving target goals. Furthermore, wide variety processes, materials, machines creates challenges in determining constraints. Therefore, this study presents ontology web language (OWL) semantically model retrieve...

The end-of-life (EoL) management of solar panel waste has emerged as an important issue related to first-generation panels in South Korea, which have already entered their retirement stage. In this study, the sustainability impacts three scenarios for recycling EoL panels, namely mechanical (MR), chemical (CR), and thermal (TR), were investigated, environmental economic benefits evaluated using life cycle assessment (LCSA) method, with landfilling reference scenario. results obtained showed...

Parts with complex geometry have been divided into multiple parts due to manufacturing constraints of conventional manufacturing. However, since additive (AM) is able fabricate 3D objects in a layer-by-layer manner, design for AM has researched explore benefits and alleviate AM. To more benefits, part consolidation consolidating fewer number at the stage product lifecycle. these studies less considered recovery maintenance end-of-life stage. Consolidated would not be beneficial lead...

A product family has been applied to minimise development costs and maximise profits. Since products in the have similar functions architecture, high potential for sustainable order prolong lifespan of by sharing new remanufactured modules. Therefore, this paper proposes a method identify configuration integrating sustainability performance platform strategy. concept is introduced enhance reusability based on compatibility terms space, function, interface. The remanufacturable modules are...

Owing to the unique technological merits of additive manufacturing (AM), design for AM, particularly eco-design has been gaining attention in improving sustainable performance AM-fabricated (AMed) parts. The main challenge harvesting potential sustainability benefits is how capture impact on performance. Though several existing studies adopted quantitative evaluation AM and investigated relationships between information AMed part, still unavailable phase. This hardly guides practice. To...

Design for additive manufacturing (DFAM) provides design freedom creating complex geometries and guides designers to ensure manufacturability of parts fabricated using (AM) processes. However, there is a lack formalized DFAM knowledge that information on how plan AM processes achieving target goals, e.g., reducing build-time. Therefore, this study presents ontology the web language (OWL) formalize support queries retrieving knowledge. The has three high level classes represent rules...

Components in complex systems are intricately interconnected with each other. When design changes needed terms of sustainability, it is necessary to understand how change propagates and affects other systems. Therefore, the objective this paper describes define cause a sustainable effect propagation by utilizing Change Propagation Analysis (CPA) system dynamics. The interconnections components investigated Design Structure Matrix (DSM) subdivided into classes checklist. likelihoods measured...

Various sustainability indicators have been developed by governments, international organizations, and companies according to their different perspectives. It makes difficult choose proper for consistent assessments of sustainable products. In this paper, we propose a framework determine specific categories design strategies, requirements customers legislation. the proposed company level approach, House Quality (HOQ) is applied understand relationship among potential category indicators,...

With high consideration of sustainability, product recovery has become a major interest manufacturers by retrieving obsolete products. Disassembly processes can make an impact on the and be necessary to develop sustainable design achieving strategy. Therefore, this paper proposes method assess disassembly complexity that represents difficulty. The component interface complexities are measured various factors from for (DFD). Then, modified entropy theory with considering number components...

Although additive manufacturing (AM) enables designers to develop products with a high degree of design freedom, the constraints AM restrict freedom. One key is use support structures for overhang features, which are indispensable in processes, but increase material consumption, costs, and build time. Therefore, controlling structure generation significant issue fabricating functional directly using AM. The goal this paper propose knowledge-based algorithm reducing whilst considering...
