Laser powder bed fusion of differently designed NiTi stent structures having enhanced recoverability and superelasticity

Tubular mesh-structured NiTi stents have been integral to the biomedical industry in the treatment of arteries’ narrowings or blockages. Conventionally manufactured stents are not patient-specific and the process consists of a series of expensive and time-consuming tube drawings, laser cutting, and post-processing techniques. In this study, laser powder bed fusion (LPBF) was utilized to fabricate four differently designed NiTi stent structures …
