Process optimization and microstructure study of laser powder bed fusion processed Custom 465 steel
Custom 465 (C465) stainless steel is extensively used in various industries such as aerospace, oil and gas drilling, medical and firearms industry to name a few. However, 3D printing this steel from the Laser Powder Bed Fusion (LPBF) process causes cracks to form on the finished sample. In this pape...

| Summary: | Custom 465 (C465) stainless steel is extensively used in various industries such as aerospace, oil and gas drilling, medical and firearms industry to name a few. However, 3D printing this steel from the Laser Powder Bed Fusion (LPBF) process causes cracks to form on the finished sample. In this paper, the author analyzes the properties of the 3D printed samples of C465 stainless steels, analyzes why cracks occur and provides suggestions to fabricate crack-free C465 samples. This is an ongoing project, and the author hopes the information and suggestions provided here would eventually, lead this project to completion. |
