Delta Qualification Program Overview
Qualification of additive manufacturing (AM) machines and materials is a major barrier to the broad adoption of AM. Generating the requisite data and models requires significant resources to produce statistically significant data, which requires generating test coupons under a controlled process and performing testing and analysis of the resulting data. These processes are then “frozen” with no changes to key process variables allowed. There is no standards-based guidance for what is required when a change to the process is needed. This greatly inhibits the agility of AM processes to respond to changes in the technology or supply base and allows 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.
The objective of this project is to employ technical teams to demonstrate a single change to a selected baseline process by employing advanced numerical, analytical, and experimental methodologies to accelerate process change and reduce the cost of doing so. The goal is to achieve at least the equivalent performance of the baseline material.
The project will use the following technical approach:
