An informal pre-conference social event is scheduled for Sunday evening.  The cost is included in the full registration fee.  The purpose is to provide a venue where attendees can renew old friendships and meet new people prior to the start of technical sessions. Beverages and light refreshments will be served.  It will be held on the sixth floor of the Hilton Hotel in the Grand Ballroom Foyer from 5:30-6:30 PM. You may also register and pick up your conference packet at that time and place, or any time after 1 PM Sunday.


The theme of the Monday morning plenary session is "Emerging Women Leaders in AM". Chaired by Professor Carolyn Seepersad at The University of Texas at Austin, six presentations will be made by outstanding women researchers early in their careers.  Following will be the two traditional technical presentations by the FAME Award winners. You are encouraged to grab a quick lunch at the close of the session at 12:10 PM, and then to return at 12:45 PM for a panel discussion dealing with issues related to becoming and being an emerging woman leader in AM. The panel will consist of the plenary session emerging women leaders. The panel moderators are Professor Seepersad and Dr. Cindy Waters from the NSWCCD-Carderock Division. The room location is Salon G in the sixth floor of the Hilton Hotel, and the session will end in time for attendees to move to the afternoon parallel sessions at 1:30 PM. 


The annual Awards Banquet will be held at the Hilton Hotel (500 E. 4th St) near the meeting rooms in Salons HJK.  The banquet cost is included in the full registration fee and for those one-day registering for Monday.  Additional tickets may be purchased at registration.  No transportation will be provided. Please see the final program for details. Given complications of COVID-19, the banquet may have a different look and format from previous years to maximize the safety of attendees.  FAME awards will be presented at the awards banquet. 



Lunch is provided for all attendees on Tuesday, July 26 in Salons FGH on the sixth floor ot the Hilton Hotel.  Cost is included in the registration fee. Please see the final program for room information and times.

For students, a special program and panel will be held during the lunch period in Salons FG. The theme is: "How to be prepared for Careers in Additive Manufacturing (AM) - A panel discussion with AM experts across application domains". Professor Guha Manogharan from Penn State University will moderate the panel. The four panelists represent various career paths and stages:

After receiving her doctorate, she worked as a postdoctoral research associate at the Next Manufacturing Center at CMU. She then served as an assistant professor in the materials and manufacturing program at Worcester Polytechnic Institute, before joining CMU as an assistant professor in Fall of 2021. Dr. Narra’s additive manufacturing process design research lies at the intersection of process modeling including numerical, analytical, and semi-analytical methods, processing experiments, materials characterization, and data-driven analysis.   


Maryna Lenina

Maryna is an AM Academy - Product and Partnership Manager. She joined EOS in the summer of 2016 as an Applications Engineer for metal AM, then transitioned to digitalization topics, and currently supports the development and delivery of training content. She believes that education plays a key role in implementing emerging technologies, including industrial 3D Printing, and successfully transforming organizations.


Maryna earned her master's degree in mechanical engineering from Texas A&M University, Korea Institute of Science and Technology (KIST), and the National Technical University of Ukraine Polytechnic Institute. At KIST she did research about the flexible floating ring seal that is used to reduce air leakage and increase compressor efficiency. 


Now together with EOS Additive Minds, she shares her expertise in facilitating innovation with industrial 3D Printing. Maryna works on the development and delivery of Additive Manufacturing programs and products for professional development. 


Nicholas Bass

Nick Bass, is the Lead AM Engineer at an AM service bureau. He holds a Masters degree in Additive Manufacturing & Design from Penn State. At Cumberland Additive, Nick supports manufacturing projects with Powder Bed Fusion in rigorous industries like Aerospace, Defense, and Energy.

The abstract submission deadline is past, but student award applicants may submit an abstract (poster presentation only) along with their application for a travel award to meet this requirement.  If selected for a travel award, the abstract will also be accepted.

  3. “Student” means an undergraduate or graduate student currently enrolled in a US institution of higher learning.  Postdoctoral scholars are not eligible.

  4. Awardees are responsible for the cost of their own accommodation and transportation.

  5. The number of awards is limited, and organizers reserve the right to limit the number of award recipients per university or per faculty advisor to fairly distribute the funds among institutions across the nation.
