This will be held on March 25, 2022 from 2:00pm – 3:00pm in NERC 1012.

 

Abstract: Additive printing (aka 3D printing or additive manufacturing) is one of the advanced manufacturing techniques. It shows great advantages for prototyping and low-volume manufacturing because of high customization, controllability and easy setup. There are plenty of 3D printers available on the market for all kinds of prototypes; however, additive printing has not been thoroughly investigated in several areas, including but not limited to 1) process development for in-space additive manufacturing and assembly, 2) new material characterization, 3) quality assurance and real-time inspection, 4) micro/nano scale prototyping. Dr. Qin built up a ‘machine shop’ trying to address some of those
challenges. His group investigate how to integrate his electrohydrodynamic technique (known as EHD printing) for NASA’s in-space 3D printer to manufacture on-body wearable sensors. In this research seminar, Dr. Qin will first introduce his group’s recent NASA parabolic flight test results. Dr. Qin validated and confirmed that EHD printing is a unique gravity-free 3D printing technique. His recent efforts in modeling, in-situ monitoring, data analytics, quality assurance, and control schemes will be introduced. Some other highlights are ‘in-situ NDE for AM and data fusion’, ‘digital twin for micro/nano manufacturing systems, and ‘origami design for manufacturing’.
