Latest Patents

**Robotic Systems for Additive Manufacturing.** This invention describes a manufacturing system built around a frame with an interior workspace and an overhead robotic arm suspended from a ceiling-mounted gantry. A control system directs the arm to move parts among manufacturing processes. The system may combine stations for microassembly, aerosol jetting, intense pulsed light photonic sintering, fiber weaving, and 3D printing, enabling multiple production steps within one coordinated environment.

**In-Process Ultrasonic Polling of 3D-Printed Crystalline and Semi-Crystalline Electroactive Polymers.** This invention presents methods and systems for producing structures with selectable piezoelectric properties through additive manufacturing. An ultrasound-generating device connected to the print head transmits acoustic energy that vibrates the head as feed material is extruded. The print head moves relative to a supporting substrate, depositing successive layers to form the structure.

Career Highlights

Tofangchi’s inventions bring together robotics, additive manufacturing, and process control. His work on robotic systems emphasizes coordinated movement between specialized manufacturing stations, while his ultrasonic approach explores how acoustic energy during printing can influence the properties of electroactive polymer structures.

Collaborations

Tofangchi is associated with the University of Louisville Research Foundation, Inc. His listed coworkers include Keng Hsu and Thomas A. Berfield.

Conclusion

Alireza Tofangchi’s patent work highlights two complementary directions in additive manufacturing: integrating robotic systems across production processes and using in-process ultrasound to help tailor the properties of printed structures.
