The latest laser technologies, include femtosecond lasers and multi-axis lasers that can create intricate Nitinol micro parts. This article explores the capabilities of laser cutting and Nitinol, the impact of advanced laser technologies, post-processing techniques like electropolishing (EP), and the challenging yet promising use cases in the ever-evolving field of medical devices.

Nitinol Manufacturing and Laser Cutting


Nitinol, a nickel-titanium alloy renowned for its shape memory properties, has found an ever expanding realm of possibilities in medical devices with micro laser cutting. This process involves using highly focused laser beams to precisely cut, shape, and modify Nitinol components on a microscopic scale. The flexibility and precision afforded by Nitinol micro features make it an invaluable tool in the creation of intricate parts for medical devices.

Advancements in Laser Technologies:

  1. Femtosecond Lasers: Femtosecond lasers, with pulses in the femtosecond range (one quadrillionth of a second), have revolutionized Nitinol micro laser cutting. The ultra-short pulses enable exceptionally precise and clean cuts, vaporizing micro areas of material while minimizing heat-affected zones. This level of precision is crucial when working with Nitinol, as it ensures the material’s shape memory properties remain intact.
  2. Multi-axis Lasers: Multi-axis laser systems add a new dimension to micro cutting Nitinol. These lasers enable cutting along multiple axes, providing greater flexibility in shaping the intricate features that are revolutionizing healthcare. This capability is particularly valuable when crafting complex micro parts for advanced medical devices, allowing for the creation of three-dimensional structures with unparalleled precision.

Post Processing of Micro Laser Cut Parts

While micro laser cutting achieves intricate shapes, post-processing like electropolishing plays a vital role in enhancing the final product. Electropolishing ensures smooth surfaces of Nitinol micro parts, improving both corrosion resistance and biocompatibility. This step can be crucial, especially in medical devices where the quality of surface finish can impact performance and patient safety.

Challenging and Emerging Use Cases for Micro Laser Cutting of Nitinol:

  1. Microelectromechanical Systems (MEMS): Nitinol micro parts are finding application in MEMS for medical devices. These tiny, flexible components are used in advanced sensors and actuators, enhancing the capabilities of diagnostic tools and implantable devices.
  2. Neurovascular Interventions: The flexibility and precision of Nitinol micro parts make them ideal for neurovascular interventions. Micro laser-cut stents and guidewires navigate intricate pathways, providing minimally invasive solutions for conditions such as aneurysms and cerebral artery stenosis.
  3. Endoscopic Procedures: Advancements in Nitinol micro laser cutting are revolutionizing endoscopic procedures. Micro parts enable the creation of smaller, more flexible tools for improved outcomes during minimally invasive surgeries.
