This work analyses the feasibility of a Finite Element model of cardiovascular stents produced by Selective Laser Melting (SLM) technique, identifying general guidelines for numerical simulations on these devices. Given the high geometrical variability of SLM parts at the microscale, microtomography scans allowed to build a stent model through beam element discretization. Preliminary studies were conducted to compare traditional hexahedral mesh with beam mesh, and finally the SLM stent geometry was numerically investigated.

Abstract

This work analyses the feasibility of a Finite Element model of cardiovascular stents produced by Selective Laser Melting (SLM) technique, identifying general guidelines for numerical simulations on these devices. Given the high geometrical variability of SLM parts at the microscale, microtomography scans allowed to build a stent model through beam element discretization. Preliminary studies were conducted to compare traditional hexahedral mesh with beam mesh, and finally the SLM stent geometry was numerically investigated.
