Welcome to the AMIR Lab 

Who We Are?

Our primary research objective revolves around exploring the intricate process-structure-property-performance relationships in metallic alloys and composite materials during advanced manufacturing. To achieve this, we employ a combination of ex-situ and in-situ characterization techniques, which provide valuable insights into the behavior of these materials.

Our mission is to address the key processing challenges in advanced manufacturing technologies, with a strong focus on achieving significant cost reduction and enhanced energy efficiency.

In pursuit of our research interests, we concentrate on the design and development of innovative alloys and compounds that are compatible with fusion-based or non-beam-based additive manufacturing processes. Our research is centered on both fundamental and applied aspects, particularly in the domains of laser-beam powder bed fusion and binder jet 3D printing processes. Additionally, we explore various post-processing treatments, with a specific emphasis on surface engineering and heat treatment, to gain a comprehensive understanding of materials' microstructural evolution and mechanical response.

Ultimately, our overarching goal is to enable efficient machine learning on a wide range of materials, processes, and imaging modalities. By doing so, we aspire to contribute significantly to the advancement of additive manufacturing technologies and materials science, facilitating the development of more efficient and innovative manufacturing processes across various industries.

We are looking for enthusiastic undergraduate and graduate students as well as postdoctoral researchers and visiting scholars to join our group.

Field trip: It was another remarkable experience taking about 40 undergraduate students from my MMAE 485 (Manufacturing Processes) class to visit #DMGMORI Company, a highly regarded manufacturing company in the Chicagoland area. During the visit, they had the opportunity to network with key professionals in the industry and share information that could open doors to potential internship opportunities. They also learned about multiple machines such as LaserTech 30 (LPBF), DMU50 (CNC), LaserTech 3000 (DED Hybrid), and LaserTech 125 (DED Hybrid).
