New laser technique improves implants

摘要

Researchers at Purdue University are developing technologies to manufacture artificial implants 10 times faster, last three times longer and cost less than devices currently on the market. Conventional manufacturing of orthopedic implants typically involves coating the surface of milled or molded titanium parts with a polymer material that adjoins the patient's natural bone or tissue cells, said Dr. Yung Shin, professor of mechanical engineering and director of Purdue's Center for Laser-Based Manufacturing. The polymer's life expectancy of about 10 years requires some patients to undergo several implant procedures during their lives.
