Rapid Quality Inspection Specimen (Auburn Univ.)
Assessment of Material Quality and Build Health through a Rapid Quality Inspection Specimen (RQIS)
Undesired variations within the LB-PBF can adversely affect the final part quality. Detecting such variations is challenging, costly and time consuming. Hence, implementation of a rapid, efficient and effective procedure to detect potential issues after fabrication is needed.
Impact (Standardization Gaps)
Gap PC3: Machine Health Monitoring. (Low Priority)
Gap M6: Tracking Maintenance. (Medium Priority)
Gap D17: Contents of a TDP. (High Priority)
Gap D26: Design for Measurement of AM Features (Medium Priority)
Gap PC2: Machine Calibration and Preventative Maintenance. (High Priority)
Gap PC4: Machine Qualification. (Medium Priority)
Gap FMP1: Material Properties. (High Priority [Metals])
The rapid quality inspection specimen (RQIS) will contain several features designed to identify and quantify any deviations build/material quality through a series of tests that can be performed within a few hours after the build is removed from the machine. These include: dimensional accuracy, geometry compliance, surface roughness at various surfaces, and mechanical properties that can be rapidly evaluated such as torque and angle of twist.
Deliverables: (1) Part design, (2) Location dependency analysis,(3) Sensitivity to defects analysis, (4) Fully detailed and implemented procedure
