What is it about?
3D printing makes it possible to create an efficient NiTi (nitinol) structure with shape memory. It holds more load with less material. This work investigates its performance through several load-release cycles. It reveals the degradation of its shape memory capacity, crucial for future applications.

Why is it important?
This is one of the very few papers that describes the use of the exotic material nitinol when used to make the special structure discussed. Nitinol is already used in several applications, for example in prosthesis. This work contributes to a wider use of nitinol for that application and many others. The flexibility of 3D printing to create complicated geometries is a hot topic. It is even more attractive when nitinol is considered to make the structures. This is mainly due to the shape memory capacity, which makes it a very special material.
Perspectives
The fact that this is one of the very few papers combining NiTi (nitinol), 3D printing and cyclic loading is a great opportunity for innovation. It is already clear that nitinol and 3D printing can facilitate people's lives in many ways, from customized prosthesis to actuators without moving parts.
