Stent Manufacturing Using Cobalt Chromium Molybdenum (CoCrMo) By Selective Laser Melting Technology.

This paper reviews the capabilities of additive manufacturing (AM) technology and the use of Cobalt super alloy stent fabrication by looking at the dimensional accuracy and mechanical properties of the stent. Current conventional process exhibit many processes which affect the supply chain, costing, and post processing. By alternatively switching to AM, the step of production can be minimized and thus customization of stent can be carried out according to patients need. The proposed methodology is a perfect choice as surgeons need to have an accurate size during stent implantation. It also is able to reduce time-tomarket delivery in a matter of hours and from days. The suggested stent model was taken from the third party vendor and flow optimization was carried out using Materialise Magics TM software. By using SLM125™ printer, the printing parameters such as Energy Density (DE), Laser Power (PL), Scanning Speed (SS) and Hatching Distance (DH) was used to print the stent. The properties of the finished product, such as strength, surface finish and orientation was investigated. [ABSTRACT FROM AUTHOR]
