Abstract:

BACKGROUND: Electron beam melting rapid prototyping technology, has the characteristic of shaping precisely and complexly, is a new type of rapid prototyping technology using metal powder. Now, it has shown unique advantages in the fields of aerospace, automotive and medical implant equipments.
OBJECTIVE: To explore the properties of the product, the customization ability of orthopedic implants through electron beam melting rapid prototyping, especially the ability of inducing bone ingrowth.
METHODS: We retrieved PubMed Database, China Journal Full-text Database, and China National Knowledge Infrastructure, as well as Dongfang Daily, World Science, and Chinese Journal of Orthopaedics by hand, and assembly documents in Chinese and English. Retrieval time was up to September 2013. Inclusion criteria: ① articles concerning electron beam melting rapid prototyping technology; ② articles addressing surgical implants. A total of 50 articles were included.
RESULTS AND CONCLUSION: Electron beam melting state Ti6Al4V orthopedic implant has a good comprehensive performance, since the three-dimensional porous structure via electron beam melting rapid prototyping, which has a characteristic of customization, can induce bone ingrowth.
