Mechanical Characterization of Additively Manufactured (3D-Printed) Metal Alloys
We are developing multiscale characterization methods for additively manufactured(3D-printed) materials with various temperature range. Bulk scale characterization is conducted with bulk scale tensile-fatigue mechanical testers, and small-scale characterization is conducted with in-situ mechanical tester. Also, for small-scale characterization, we are working on meso- and micro-scale testing methods with the fabrication of femtosecond laser-based tensile specimens and small-scale mechanical testers to understand how its mechanical behavior differs compared to that in bulk scale.
