CMAM collaborator Samantha Snabes - UMD Alumni Business of the Year 2023

Samantha Snabes, ‘06 B.S., ‘06 B.A., ‘11 M.B.A., is relentlessly focused on social responsibility, and the company that she helped co-found, re:3D, is committed to empowering local change-makers by developing quality, industrial printers that can be adapted in new markets. Founded in 2013 as a spin-off of Engineers Without Borders-NASA Johnson Space Center, the re:3D team manufactures large, affordable industrial printers capable of printing virgin or recycled filament, pellets, or flake in the USA that are exported to over 60 countries. re:3D Inc. is breaking through the current limitations of 3D printing to unlock new applications and growth markets worldwide. 

The Ph.D. assistantship will focus on polymer materials, environmental aging, multi-physics modeling, machine learning, and mechanics modeling. The project is funded by the National Science Foundation, and the selected Ph.D. student will be actively involved in an extensive experimental campaign. Additionally, the student will be responsible for developing a cutting-edge numerical tool that combines multiphysics, machine learning, and advanced Finite Element Modeling (FEM).

This project is in collaboration with France and involves several month stay in Paris and Lille. 


Professor Moussa Nait Abdelaziz visit

In July 2023, we had the honor of hosting Professor Nait Abdelaziz at the CMAM lab for a productive two-week visit. During his stay, Professor Nait Abdelaziz engaged with our CMAM Ph.D. students, providing valuable insights and expertise in their respective research areas. The students had the opportunity to present their ongoing work, and Professor Nait Abdelaziz offered constructive feedback and guidance, enriching their research endeavors.

The visit also served as a platform for fostering potential future collaborations between Professor Nait Abdelaziz and our research team. Discussions on potential joint research projects and knowledge exchange initiatives were held, laying the groundwork for fruitful collaborations in the field of polymer science and engineering.
