Additive Manufacturing: Overcoming Fatigue Strength Hurdles in Orthopedic Implants

Additive Manufacturing: Overcoming Fatigue Strength Hurdles in Orthopedic Implants

About video

Orthopedics has experienced a proliferation of additive manufactured implants in recent years. Additive manufacturing has primarily been used for hip cups and spine devices. But why not other implants like hip stems and screws? This OMTEC session brought together multiple perspectives to discuss fatigue strength challenges that orthopedic companies face in expanding their use of additive manufacturing. Speakers gave short presentations highlighting how fatigue plays a role in designing, testing and manufacturing additive implants.

Learning objectives included:

  • Understanding primary fatigue strength concerns with additive manufactured implants
  • Learning how companies are handling these concerns in their product development initiatives
  • Receiving insight into future additive manufactured orthopedic applications
