This one-hour-long rapid fire allows each speaker 15 minutes of presentation time, followed by 15 minutes of group Q&A. Rapid fire subjects are:

Easing the Secondary Production Process During Design
Maria Pettersson, Ph.D., Orthopaedic Industry Specialist for GE Additive, will explain why the design stage is where the smart decisions are made in additive manufacturing — not only on ways to increase clinical outcomes and additive processes, but also to ease post-processing. In these areas, the process can be made efficient and cost-effective. Dr. Pettersson will offer tips and tricks on orientation, supports, stock material and design features.

Designing Porous Structures
Alejandro A. Espinoza Orías, Ph.D., Director of the Orthopaedic Surgery 3D Printing Laboratory at Rush Medical College, will bring perspective from working with surgeons to produce additively manufactured parts. Many industries have adopted additive to mass produce parts on demand. In the medical arena, however, part manufacturers need to be familiar with certain concepts before proceeding to mass production. Some of these considerations are as diverse as the patient population meant to benefit from additive, in addition to considerations for patient privacy, metallurgy, mechanical properties and cleanliness.

Enhancing Design through Engineering and Manufacturing Collaboration
Laura Gilmour, Global Medical Business Development Manager for EOS North America, will discuss the concept that unlike conventional methods, additive manufacturing requires design and manufacturing teams to work closely together very early in the design phase. In a world where the pace of innovation is nearly vertical, it’s imperative to understand this concept early to make additive manufacturing work for you. This discussion will lend a high-level overview of best practices when working with internal or external suppliers, and will show examples of the use of additive manufacturing to create innovative medical device designs.

Attendee Takeaways

  1. Considerations to make at the AM design stage for a better post-processing experience
  2. Familiarity with appropriateness concepts for AM
  3. The latest FDA guidance on AM
  4. Best practices for working with suppliers



Pettersson 200x200Maria Pettersson, Ph.D. is an Orthopaedic Industry Specialist at GE Additive, a position she’s held since 2017. She received her Ph.D. in Material Science from Uppsala University in 2015, with the thesis “Silicon Nitride for Total Hip Replacements” with special interest in orthopaedic implants, tribology, corrosion, coatings and advanced microscopy. Dr. Pettersson joined Arcam in 2015 as an Application Engineer, with a focus on powder and customer solutions for medical customers. For a period of six months in 2017 she was based at DiSanto Technology, Arcam’s contract manufacturing division for the medical industry.

Espinoza 200x200Dr. Alejandro Espinoza Orías is an Assistant Professor in the Department of Orthopedic Surgery at Rush University Medical Center. He received a licentiate degree in Mechanical Engineering from the Universidad Mayor de San Andres (Bolivia), in addition to a Masters and Ph.D. in Aerospace and Mechanical Engineering at the University of Notre Dame. He later completed a postdoctoral fellowship in spine biomechanics at the McKay Orthopedic Research Laboratory at the University of Pennsylvania. Dr. Espinoza has an interest in spine biomechanics and degeneration, as well as expertise in 3D printing as part of the ASTM F42 Additive Manufacturing Committee. He is currently the Director of Rush’s 3D Printing laboratory.

Gilmour 200x200Laura Gilmour, Global Medical Business Development Manager for EOS North America, oversees more than 20 medical device OEMs and contract manufacturers using EOS technology. She joined EOS in 2016 after working with the company as a customer during her 15 years as a biomedical research and development engineer. Previously, she was a senior research engineer at Smith and Nephew Orthopaedics, where she and a team of engineers developed an advanced porous structure now used in orthopaedic applications around the world. She has also worked at Medtronic Spine and Biologics and Abbott Vascular, where she was responsible for translating surgical needs into medical device designs. Prior to that, she spent two years as a premarket reviewer for FDA. During her time at the agency, she was a founding member of the organization’s Additive Manufacturing Working Group. Ms. Gilmour is a member of the SME Medical Additive Manufacturing/3D Printing Working Group and the Society of Women Engineers. She holds a Bachelor’s degree in Bioengineering from the University of Pittsburgh and a Master’s degree in Biomedical Engineering from the University of Tennessee Health Science Center.
