| Abstract Scope |
The use of AM technology in industry has been increasing every year due to its ability to print complex geometries, reduce development time, and address supply chain gaps. However, a common paint point for all AM users is build interruptions. They happen for a variety of reasons such as power failure, poor design, or machine issues. With the significant cost of metal AM, there is a strong incentive to understand the effects of build interruptions on material properties. Researchers at OSU's Center for Design and Manufacturing excellence did analysis on printed AlSi10Mg, and IN-718. Each material had a interrupted and non-interrupted build consisting of tensile and fatigue specimens. Each build also utilized re-coat and tomography cameras to monitor the build. Results did not show a significant effect on Ultimate tensile strength, but the aluminum samples showed some reduction in elongation. There was also no significant impact observed on fatigue strength. |
