MIM targets bigger role in medical implants


A newly approved ASTM standard is expected to advance the use of metal injection molding (MIM) as a manufacturing method for medical implants.

ASTM F2989 is a new international specification that covers unalloyed titanium components that are used for surgical implants. It was developed by Subcommittee F04.12 on Metallurgical Materials, part of ASTM International Committee F04 on Medical and Surgical Materials and Devices.

"Through ASTM F2989, the material properties of metal injection molded unalloyed titanium components can be directly compared to components that are made with conventional methods," says Matthias Scharvogel, managing director, Element 22 GmbH, and an F04 committee member.

That's important, says Scharvogel, because MIM could reduce costs compared to titanium alloy implants produced via competing methods....
