Prof. Dr. Sumon Sarkar has gained international acclaim for a noteworthy accomplishment in advanced materials science. His most recent work was published in the esteemed international scientific journal Progress in Additive Manufacturing, which is published by Springer Nature.
The study “First Report of the Behavior of a 3D-Printed Material in an Oblique Direction Off the In-Plane Direction” makes a significant scientific contribution to the quickly evolving fields of conductive materials, advanced manufacturing, smart structural monitoring, and 3D printing.
The study was carried out at the University at Buffalo, State University of New York (SUNY), USA, using the Composite Materials Research Laboratory in the Department of Mechanical and Aerospace Engineering. Professor Dr. Sumon Sarkar worked with researcher Ethan O. Chen and renowned materials science researcher Professor D. D. L. Chung.
An Unprecedented Scientific Study
The study examines the electrical behavior of electrically conductive 3D-printed materials when current passes through the printed layers in an oblique orientation.
This study offers the first documented examination of the electrical properties of 3D-printed materials in an oblique direction, despite the fact that scientists have thoroughly studied their electrical properties along and perpendicular to their printed layers.
The research team used sophisticated electrical measurements to show that a material’s electrical resistance and inductance can be greatly affected by even a tiny shift in the direction of electrical current.
The results showed that compared to the traditional longitudinal route, electrical resistance and inductance in the oblique direction were roughly 12–13% greater. The interfaces between neighboring printed layers, which affect the electrical current route, were identified as the cause of this discrepancy.
The remarkably high inductance connected to the 3D-printed material’s internal microstructure was one particularly noteworthy discovery. The study showed an exceptional result: the measured-to-calculated inductance ratio in the oblique direction reached about 9,600.
The Research Contribution of Prof. Dr. Sumon Sarkar
Prof. Dr. Sumon Sarkar contributed significantly to the experimental study. He was in charge of creating Figure 5, gathering electrical measurement data, and assisting with the scientific assessment of the experimental results, according to the published study. Every author took part in the manuscript review process.
His work contributed to the establishment of experimental data showing how the electrical characteristics of 3D-printed materials are influenced by their interior structure and interfaces.
The study is especially significant since it strengthens the scientific basis for the creation of self-sensing structures and intelligent manufacturing systems. In the future, these structures might use electrical measurements to identify internal flaws, damage, and changes in structural conditions without the need for additional sensors to be installed in the material.
Possible Effects on Upcoming Technologies
Aerospace engineering, automobile production, robotics, smart materials, structural health monitoring, and additive manufacturing are just a few of the advanced technology industries that could benefit from the findings.
Monitoring the state of manufactured components is very important in the aerospace and other safety-critical industries. Future technologies that can detect internal flaws and track material performance while in use may benefit from the concepts investigated in this study.
Additionally, the study creates new avenues for investigation into the connection between the mechanical performance, electrical behavior, and microstructure of additively created materials.
Collaboration and Recognition in International Research
For the research team, publication in Progress in Additive Manufacturing is a significant accomplishment. The journal is an international peer-reviewed publication devoted to the advancement of additive manufacturing research and industry applications.
Accepted on October 20, 2026, the paper was formally released online as an open-access scientific publication on November 9, 2026.
