Welcome to the NSF-funded additive nanomanufacturing (ANM) page
Objective
Additive manufacturing or three-dimensional (3D) printing is widely used by engineers and designers for rapid prototyping customizable products. Unfortunately, such a rapid prototyping technique is yet to be developed for the nanoscale. The importance of manufacturing at the nanoscale lies in the extraordinary properties that materials exhibit at such small scales. Therefore, the ability to manufacture three-dimensional nanometer-sized structures becomes critically important to explore new properties and applications of nanomaterials.
This NSF-funded research aims to develop an non-destructive nanoparticle transfer process that can be potentially used for additive nanomanufacturing. Nanometer-sized structures that are a thousand times smaller than the diameter of a human hair can be transferred to any substrate in an additive way to build 3D nanostructures. The process uses a continuous-wave laser to lift and transfer the nanostructure non-destructively under ambient conditions. Such a capability is important for applications such as wearables, sensors, and other flexible electronics.

Activity
Md Shah Alam and Farzia Karim have successfully graduated from NPNM lab. Now they are Dr. Md Shah Alam and Dr. Farzia Karim. Congratulations! Thanks NSF's support for their PhD study.
Dr. Chenglong Zhao gave a seminar on the OSA Student Chapter on Feb. 28, 2020 at the University of Dayton. The concept of Laser additive manufacturing and the NSF-funded research are introduced to the graduate students at the Department of Electro-Optics and Photonics.
Conference participation from NSF-supported Student: Md Shah Alam, a PhD student who is supported by this NSF grant, attended the NSF Student Research Poster Competition in the ASME 2019 International Mechanical Engineering Congress & Exposition that is held at Salt Lake City between Nov. 8th and 14th, 2019. Shah did a poster presentation of additive nanomanufacturing. Shah spent four days on this conference and really appreciate this travel opportunity that is made happen because of this NSF-funded research. During this conference, Shah has the opportunity to interact with his peers and learn the state-of-the-art additive manufacturing that will be definitely beneficial to his future career.
Undergraduate Student Summer Research Experience: we receive several undergraduate students from Morehouse College and St. Mary’s University this summer. Students perform mentored research under Physics faculties at UD. The figure below shows that Jaylen Williams, an undergard from Morehouse College, is conducting NSF-funded nanomanufacturing research with graduate student Md Shah Alam in Dr. Zhap's NPNM lab. Jaylen presented his work at the Summer Undergraduate Research Symposium at UD.
Summer Short Course: Dr. Zhao taught a summer course. This NSF funded research is introduced the students. The students learnt how to build an optical system including the optical system for additive nanomanufacturing. The figure to the right shows that Dr. Zhao is demonstrating how to correctly align an optical system in the NPNM lab.
Dayton TechFest: The Dayton TechFest is held every year in Dayton area as a free family fun with science, technology, engineering and math (STEM). Participates includes NASA astronaut, Air Force flight test pilot, college professors, classical guitar players and others deliver entertaining and informative talks on STEM topics. This NSF-funded research is demonstrated on this event.
New system for additive nanomanufacturing: This new system (the left image) has a better resolution and image quality compared with the old version. Thank Md Shah Alam for his hard work on re-designing this system. Shah is working on the system (the right image)
