Advancing Micro/Nano Device Fabrication: Process Modeling and Control for Customized Manufacturing

Event Type
Mechanical Science and Engineering

Dr. Nazanin Farjam, Robotics Department, University of Michigan
Amy Rumsey


Increasing demand for customization in the manufacturing of integrated micro/nanosystems has prompted the development of advanced manufacturing processes capable of fabricating customizable devices tailored to specific end-user requirements. Additive manufacturing (AM) represents a unique set of processes that can be tuned on-the-fly and integrate printed components in a bottom-up manner on top of non-planar, flexible substrates. Despite the obvious advantages of these processes, the adoption of additive manufacturing for functional device fabrication, particularly at the micro/nanoscale, has been limited by challenges in achieving robost, repeatable, and predictable printing performance at this lengthscale. In my talk, I will address these challenges through a structured approached focused on providing an enhanced understanding of the physics that drive high-resolution 3D printing and the transition of this knowledge into a controls-theoretic framework for improved precision, accuracy, and quality of printed micro/nanoscale devices. Validation of the proposed framework will be provided for both a simulation of a high-resolution jet-based printing system, as well as experimental results from an extrusion-based printing process. The talk will conclude with a discussion of my future research plans.

 About the Speaker 

Dr. Nazanin Farjam is a postdoctoral researcher in the Robotics Department at the University of Michigan, collaborating with Prof. Kira Barton and Prof. Dawn Tilbury. She completed her PhD in Mechanical Engineering at the University of Michigan under the guidance of Prof. Kira Barton. Her research interests lie in the development of modeling frameworks and intelligent decision-making strategies to enhance the flexibility, robustness, and efficiency of complex manufacturing processes. Nazanin has received several awards, including the Rising Star in Mechanical Engineering from Stanford University, the University of Michigan’s Rackham Predoctoral Fellowship Award, the Richard and Eleanor Towner Prize for Outstanding Ph.D. Research, an Outstanding Master's Thesis Award, and recognition as an Outstanding Teaching Assistant.
