Nitinol for Additive Manufacturing

Effective Translation of Shape Memory and Superelastic Properties from Wrought to 3D

Carpenter Technology and their branch of 3D printing experts, Carpenter Additive, carried out a study to create a systematic framework to optimize additive manufacturing for Nitinol, focusing on three factors for success: 

  1. Stringent control of Nitinol chemistry throughout the AM lifecycle from feedstock to finished part 
  2. Optimized printing parameter sets to enable effective control over shape memory and superelastic properties 
  3. Fully dense near net shape Nitinol components to eliminate additional post-processing steps

Webinar: Success in Additive Manufacturing with Nitinol

Additive manufacturing of Nitinol allows the fabrication of complex device geometries with pre-designed porosity, homogeneous composition, high density, near net shape, and requires very little to no post-processing. As Nitinol exhibits work hardening in conventional manufacturing processes, additive manufacturing presents unique opportunities in the production of medical devices.
