3D Printing and Training Nitinol for 40 °C Actuation

How can a 49Ni–51Ti (Nitinol) component be 3D printed and trained to actuate at 40 °C?

A 49Ni–51Ti part is typically 3D printed using powder bed fusion (SLM). After printing, solution heat treatment and aging are used to tune the austenite finish temperature to 40 °C. The part is then thermomechanically trained through repeated heating–cooling cycles under load to achieve stable, repeatable actuation.
