研究目的
To explore the capabilities of metal additive manufacturing (MAM) technology in producing intricate stent structures with a customized design using ASTM F75 cobalt chromium powder, and to investigate the potential of MAM for future stent manufacturing.
研究成果
The research demonstrated the feasibility of using SLM technology for stent manufacturing, with the fabricated stents showing promising mechanical properties and biocompatibility. However, surface finish and the accuracy of elemental analysis require further optimization and verification. The study highlights the potential of MAM for customized stent production, offering a pathway to minimize production steps and tailor stents to individual patient needs.
研究不足
The study acknowledges the presence of the 'balling effect' on the stent surface, indicating potential issues with surface finish and the need for optimization. Additionally, the accuracy of carbon and sulphur content measurements via EDX was questioned, necessitating further verification with carbon-sulphur analysis methods.
