Project: Development of Standard Procedures and Metrics for Qualification of Laser Powder Bed Fusion (L-PBF) Machines and Processes

Partner Lead

NASA

Challenge

Lack of minimum requirements for the qualification of L-PBF machines and processes.

Objective

  • Develop consensus within the ASTM CoE community regarding minimum requirements for the qualification of L-PBF machines and processes.

  • Establish a standard set of procedures, test methods, and evaluations used to establish L-PBF qualification based on fundamental objectives.

  • Establish quantitative and/or qualitative metrics applicable to each evaluation to define successful machine and process qualification.

Approach

  • Use MSFC-STD-3716 and MSFC-SPEC-3717 as baseline

  • Perform critical assessment of qualification procedures and metrics

  • Identify strengths and weaknesses in the methodology of these standards

  • Develop consensus on key policies, procedures, and metrics

  • Standardize terminology regarding process (procedure) qualification, machine calibration, and machine qualification

  • Determine if process qualification should be scaled with part classification

Impact

NASA will work to develop standard procedures, metrics, and comprehensive requirements to help qualify machines and processes in laser powder bed fusion. This process qualification and assessment research aims to establish much-needed consensus in this area across the additive manufacturing community.
