June 1, 2020 - Congratulations are in order for Emily Lazarus, Melvin Cruz, and Samantha Sorondo.
Ms. Lazarus completed her bachelor's in BME and got accepted into the RIT PhD program. Mr. Cruz completed his bachelor's in Electrical Mechanical Engineering Technology. Ms. Sorondo successfully completed her Qualifying Exam, an important milestone in the RIT PhD program.
March 16, 2020 - Dr. Iris V. Rivero published a paper titled "Effect of Pre‑welding Heat Treatment on the Mechanical Properties of Friction Stir Welded Al–4wt.%Cu Alloys"
Ref: Al-Dwairi, A. F., Abdelall, E., & Rivero, I. (2020). Effect of Pre-welding Heat Treatment on the Mechanical Properties of Friction Stir Welded Al–4 wt.% Cu Alloys. Metallography, Microstructure, and Analysis, 1-11.
February 27, 2020 - Srikanthan Ramesh and Dr. Iris V. Rivero published a paper titled Process–Structure–Quality Relationships of Three-Dimensional Printed Poly(Caprolactone)-Hydroxyapatite Scaffolds in the Journal of Tissue Engineering Part A. The article frames a systematic approach for the optimization and validation of 3D printed scaffolds. They studied printing process parameters (e.g. temperature, extrusion temperature, etc.) and performed different tests to establish the mechanical properties of the printed scaffold. Additionally, they demonstrated that small defects, such as voids, negatively affect printed polymeric scaffolds.
This paper was the product of a collaboration of iMED (RIT), LIMB lab (UConn), and Prahalad Rao (UNL).

November 22, 2019 - iMED graduate students Jakob Hamilton, Samantha Sorondo, and Srikanthan Ramesh participated in this year's Graduate Showcase. Hamilton presented a poster about statistical error in residual stress measurements in metal additive manufactured parts. Sorondo gave an oral presentation in the topic of Non-Hydrofluoric Acid etchants for Aluminum 6061. Ramesh presented a poster and gave an oral presentation stimuli-responsive hydrogels with antibacterial properties. Ramesh won in his session's oral poster presentation competition.
October 15-17, Detroit MI - Jakob Hamilton presented iMED Laboratory research at the Heat Treat Conference. This work, a collaboration between iMED Laboratory and AMPrint Center at RIT, sought to study the effect of process parameters on the printed piece's density. Components were fabricated using a state-of-the-art hybrid manufacturing machine in the Brinkman Machine Tools and Manufacturing Laboratory, and applied laser power and scanning speed were found to directly influence metal characteristics.
August 2019 - iMED Laboratory Research Assistant and RIT graduate student Jakob Hamilton was recently awarded the E. Wayne Kay Graduate Scholarship for Masters students for his ongoing thesis research into metal alloys and composites for 3D printing. As one of two recipients of this nationwide award, Hamilton intends to continue working in the field of metal additive manufacturing and broadening its applicability. Hamilton would also like to thank his research advisor Dr. Iris Rivero and colleagues Srikanthan Ramesh and Samantha Sorondo for their support and encouragement throughout the research process.
August 13, 2019, Austin TX - Jakob Hamilton presented iMED Laboratory research in 5-axis hybrid manufacturing at the Annual International Solid Freeform Fabrication Symposium in Austin, Texas. This work, a collaboration between iMED Laboratory and AMPrint Center at RIT, sought to unveil challenges with 3D printing stainless steel on non-planar surfaces. Components were fabricated using a state-of-the-art hybrid manufacturing machine in the Brinkman Machine Tools and Manufacturing Laboratory, and applied laser power and scanning speed were found to directly influence metal characteristics. Future work aims to develop hybrid manufacturing to widen its applicability.
