Additive manufacturing

My interest in additive manufacturing comes from two different sides: I am interested on the fundamental aspects of materials synthesis, and how different printing techniques and conditions affect the microstructure, and ultimately the properties, of the materials. But I am also part of a project aimed at augmenting the capabilities of 3D printing technologies by integrating additive manufacturing with nanomanufacturing, for instance as a way of achieving the rapid prototyping of electronic devices.

As part of this effort, I took part on a workshop at NIST where I provided my personal take on the challenges on understanding the properties of the material through its lifecycle: Measurement Science Roadmap for Polymer-based Additive Manufacturing This presentation also showcased some of the research being carried out in this area.

From a experimental point of view, I am leveraging Argonne’s Advanced Photon Source to look at how we can modify polymer 3D printed materials through their infiltration with inorganic materials. I am using X-ray absorption spectroscopy techniques to extract structural information about the coordination of inorganic cations inside the polymer as the inorganic phase nucleates.

I am also building on my expertise on semiconductor processing to develop models that help establish a connection between the 3D printing process and the microstructure of materials, particularly during the additive manufacturing of metals. This is part of a larger effort involving different groups at Argonne.
