Driver coronary stent mri safety4/6/2023 ![]() ![]() Our results indicate that the association of laser parameters in spot overlapping, and pulse energy contributes to reduce variables and to analyze the surface topography making laser power and feed rate of great significance in the manufacturing process of nitinol. ![]() In this work, we presented the influence of laser cutting parameters (i.e., feed rate, laser pulse frequency, pulse width and laser power) on surface roughness of Nitinol manufactured by fiber laser cutting. Nitinol is a self-expanding material with the unique capacity of self-deployment and performance in the medical industry. Fiber laser cutting is capable to generate micro geometries with high accuracy and low surface roughness. Medical devices require features at the micro-scale which represent a challenge for the manufacturing process. ![]()
