Abstract
ABSTRACTThis paper describes the design, analysis, and fabrication of a cardiovascular stent on a SS316L using 3D photochemical machining (PCM). Finite element simulation has been performed to investigate the mechanical behavior of the designed stent. The buckling, stress, and displacement of the stent are computed and analysed. Efforts are made in the replacement of a conventional tedious photo-tool masking process with a more efficient and rapid process of micro-image printing on a 3D seamless tube. The experimentations are performed by using ultrasonic enhanced photochemical machining. The analysis of results show a significant improvement in the etch rate due to ultrasonic vibration. It is observed that the etch rate is approximately 2.7 times higher than the conventional PCM process. Furthermore, it is also observed that the maximum etch rate is achieved at a temperature of 353 K and a concentration of 700 g/l in ultrasonic vibrations. The results show the cost effectiveness and usefulness of the new technique for mass production.
