FMEA-TRIZ Analysis of Reused Ti6Al4V Powder in SLM

Selective laser melting (SLM) allows powder reuse in consecutive cycles, a cost-effective and sustainable practice. However, repeated reuse can degrade powder quality, impacting the final product’s mechanical properties. This study presents a methodology combining Failure Mode and Effect Analysis (FMEA) with the Theory of Inventive Problem Solving (TRIZ) to address issues in reusing Ti6AL4V powder in SLM. The approach identifies and mitigates potential failures while leveraging an AI-based chatbot to expedite solution-finding. A case study is implemented to demonstrate the FMEA-TRIZ approach proposed in this paper, showcasing the potential benefits of this innovative methodology.
