Dr. Chmielus’ Lab is focused on the influences and relationship of composition, impurities, manufacturing, and processing parameters on the microstructure and properties of structural and multifunctional metals in bulk, foam, thin films, and single crystalline form with a focus on 3D structures produced by additive manufacturing.

Current projects involve different materials, such as Copper, Ni-based superalloys and Magnetic Shape Memory Alloys (MSMAs), as well as different Additive Manufacturing techniques such as Binder Jet Printing (BJP) and Laser-Engineered Net Shape (LENS), and a variety of characterization techniques.

Current collaborations include other Pitt faculty, researchers from Ohio State University, Boise State University, England, Poland, Finland, Spain, Germany, ExOne and General Carbide.


We use techniques such as Optical microscopy, SEM, EDS, XRD, DSC and others to characterize our samples.


We analyze microstructures through microscopy, EBSD and image post-processing.

Binder Jetting

One of the Additive Manufacturing techniques we use is Binder Jetting with ExOne machines such as the X1 Lab and Innovent.

Direct Energy Deposition

Another Additive Manufacturing technique we use is LENS, a type of powder-flor-based Direct Energy Deposition technology.

Our Group

Our group is composed of several graduate and undergraduate students that help each other all year long.


We have outreach projects for elementary and high school kids to get to know how cool Materials Science is, especially supporting SWE events.

Shape Memory Effect

We show Shape Memory alloys like NiTinol in our outreach stands, as they are similar to our Magnetic shape memory alloys we use in the lab.

Additive Manufacturing

Additive Manufacturing (AM) has challenged the current design process and expanded the potential of different alloys in the medical, dental, robotic, transportation and so many other fields. The group of 3D manufacturing technologies, allow to build more complex shapes, reducing cost and time. We study the potential applications, microstructure and properties of metallic alloys produce via AM (Binder Jet Printing, Direct Energy Deposition).

Magnetic functional materials are those that respond to a magnetic field by changeing their shape (Magnetic Shape Memory Materials) or their temperature (Magnetocaloric). We aim to improve the current knowledge of these materials, mainly with regards to advanced manufacturing methods, while studying effects of composition, porosity, magnetic anisotropy and functionality.

Functional materials




Our goal is to research the structure and properties of materials and evaluate their potential in the Advanced manufacturing field.
