EBM (electron beam melting) technology is a suitable additive manufacturing technology to produce complex aerospace components, such as the BALD (Bleed Air Leak Detect) bracket. Asdeposited and HIPed brackets have consistent mechanical properties regardless of location or orientation within the build chamber, meeting the ASTM specification for wrought Ti-6Al-4V material for yield strength, ultimate tensile strength, and elongation. Component testing also satisfied the required mechanical performance for nonflight-critical hardware. Numerous brackets can be placed into the build chamber at various locations and orientations to maximize the production rate without sacrificing component quality. A simple cost analysis shows that EBM technology provides a 50% cost reduction over the current production method. Additional certification will be required prior to full production.
