Project framework for enabling rapid qualification and industry adoption.
Problem
Additive manufacturing (AM) machines and materials qualification are major barriers to broad AM adoption. Generating the requisite data and models requires significant resources to produce statistically significant data. This qualification process requires generating test coupons under a controlled process and testing and analysis of the resulting data. These processes are then “frozen” with no changes to key process variables allowed. Standard-based guidance does not exist for requirements when a process change is needed. This greatly inhibits the agility of AM processes to respond to changes in the technology or supply base, allowing only one path to implement change to a qualified process — a total requalification, which may cost more than $3M per machine/material combination and take several years.
Objective
Develop a rapid qualification framework for metal AM laser powder bed fusion (PBF-L) processes that can be achieved with a data-driven solution to minimize the reliance on costly and time-consuming post-build testing.
Technical Approach
This project will be executed using a data-driven framework, integration of key stakeholders, and the utilization of advanced technologies. The project will be organized into seven tasks that cover various aspects of the qualification process for metal additive structures: data collection, advanced sensing and data fusion, qualification framework, manufacturing and testing, demonstration component and process verification, workforce development and mobilization of rapid qualification, and data management. Each task will have specific deliverables and milestones, ensuring a systematic and well-coordinated approach to achieve the project objectives.
