| Abstract Scope |
Additive manufacturing (AM) has revolutionized industries by allowing the creation of complex, customized parts. The quality of the powder used in AM is critical for the integrity and performance of the final product, as contamination can lead to defects and reduced mechanical properties. To ensure consistency and adherence to quality standards, a delta qualification process is essential when introducing new powder products. The Statistical Testing for Equivalency in Powder Suppliers (STEPS) program outlines an approach, including the evaluation of physical and chemical properties of Ti-6Al-4V powder produced by AP&C and mechanical testing of printed laser powder bed fusion (LPBF) and laser powder feed directed energy deposition (L-DED) coupons. Advanced techniques will be employed to assess powder quality and mechanical performance, following established qualification programs. Overall, delta qualification is vital for integrating new powders and enhancing the additive manufacturing supply chain. STEPS provides a structured roadmap for onboarding new powder sources. |
