| Abstract Scope |
It is widely recognised that in-process monitoring of additive manufacturing (AM) processes is crucial to providing robust quality assurance procedures, leading to increased acceptance of AM parts in critical applications. Although some of the gains of in-process monitoring are intangible, there are clear economic arguments that can be made to quantify the benefits of a system for different applications. This works aims to answer the question: what detection performance needs to achieved for an in-process system to be cost effect? We look at a range of industry case studies across the aerospace and nuclear industries that cover different production volumes, part costings and inspection requirements. Different costs models are analysed, capturing a monitoring system’s ability to stop production of a defective part or replace conventional non-destructive evaluation processes. Total production savings from implementing in-process monitoring range from 0% to 40% in the case studies presented. |
