Traditionally cast fuel elbows used in aerospace applications, have had issues meeting minimum wall thickness requirements. Metal additive manufacturing (AM) provides an alternative fabrication method that could allow for consistent, acceptable quality parts, even in various aircraft carrier field environments. However, there are some disadvantages to metal AM, such as waste in powder bed fusion. This project explores the effects of powder reuse on the final geometry of printed parts through non destructive testing methods and explores potential design changes required and the possible need to accommodate for post processing machining.
