Promising approach for biodegradable stents made of a newly developed Iron Manganese alloy. Synthesis by selective laser melting leads to a modified microstructure, which has a positive effect on the mechanical and corrosion properties.
Bioabsorbable metals are new materials for medical applications where only temporary functionality is required. They then decompose into non-toxic components. The selective laser melting (SLM) process offers great potential for producing biodegradable metallic materials for customized implants. By appropriate process control, the microstructure - and thus the desired mechanical and corrosion properties - can be manipulated. In the current publication in the journal Advanced Engineering Materials, scientists from IFW Dresden report that a novel iron manganese alloy has been optimized in this way for the use as bioabsorbable vascular implants and has undergone first functionality tests.
