Investigating Properties of Metals Produced by Additive Manufacturing. 
Additive manufacturing (AM), or 3D printing, is a rapidly evolving field that has the potential to revolutionize the way we think about designing and fabricating complex shapes. AM is in stark contrast to the much more widely applied fabrication process of subtractive manufacturing, in which parts are made by machining material away from a larger block of material to achieve a final 3D shape. Using additive manufacturing, components are fabricated by depositing materials in a layer-by-layer fashion in order to produce 3D parts with complex shapes that may not be easily fabricated using more traditional techniques.

This project will focus on characterization of additively manufactured metals. In AM of metals, a high power laser is used to melt metallic powder or wire to fuse it to the material layer below, allowing for 3D shapes to be produced. The local heating leads to interesting microstructural characteristics that can affect the overall part performance. This project will provide the student with hands on experience in a variety of experimental techniques used to characterize microstructure and mechanical properties (e.g., strength and ductility) of materials, and it will expose the student to the exciting field of additive manufacturing.
