Additionally, it demonstrated compliance with the AMS7011 material requirements for the Ti-6Al-4V alloy. This accomplishment was made possible through the implementation of post-deposition hot isostatic pressing (HIP). JEOL’s JAM-5200EBM is the first Electron Beam Powder Bed Fusion (EB-PBF) machine recognized to meet AMS7011 requirements since it was “first established on another EB-PBF manufacturer’s model,” says the company. The AMS7032 OQ standard evaluates the ability of an additive manufacturing powder bed fusion machine to consistently meet material specification requirements while maintaining process control and stability over multiple builds.
“JEOL has provided metrology, analytical, and electron beam manufacturing instruments for over seventy years and understands that manufacturers must have confidence in their tools,” said Bob Pohorenec, President of JEOL USA. “Meeting the AMS7032 operational qualification standard ensures manufacturers that the JAM-5200EBM is capable of producing aerospace-grade material with stable performance and meets all material specification requirements. This achievement is a testament to our commitment to quality and reliability.”
JAM-5200EBM offers alternative 3D printing solution for aerospace
In adherence to the OQ procedures outlined in AMS7032, three identical builds were conducted using reused powder conforming to the AMS7015 specification. These builds, covering the entire JAM-5200EBM build envelope, included a substantial number of Ti-6Al-4V specimens in all three orientations. Subsequently, the specimens underwent comprehensive testing, including radiography, tensile testing, chemical composition testing, microstructure evaluation, and other assessments at an ISO17025-accredited laboratory.
The testing results not only emphasized the robust stability of the JAM-5200EBM machine but also highlighted a notable strength: the system generates material with exceptional ductility and minimal anisotropy. This attribute provides designers considerable latitude in part orientation within the build envelope, fostering increased adaptability in Design for Additive Manufacturing (DfAM) and unlocking opportunities for optimized designs. The findings were displayed at the Autumn gathering of the SAE AMS AM Additive Manufacturing Metals committee and the NRC Workshop on Advanced Manufacturing Technologies for Nuclear Applications, both conducted in October.
For aerospace businesses, this advancement offers a new 3D metal printing option for crucial manufacturing parts. It provides access to JEOL’s 70+ years of electron beam expertise, ensuring compliance with stringent standards to prevent failures.
Recently, JEOL introduced its JAM-5200EBM system to Cumberland Additive in Pittsburgh International Airport’s Neighborhood 91. The system was operational in just six days and within three weeks it completed an AMS 7032-compliant build.
