Bruker’s three-dimensional microscopy for production-line roughness metrology improves manufacturing yields and implant longevity.

More than one million joint implants are currently produced every year, with a growth rate of nearly 9%. Lifetime and safety expectations continually increase, which place ever tighter requirements on the development and manufacturing processes.
Both shape and roughness are critical parameters that must be controlled to ensure proper function and lifetime of orthopedic implants.

Bruker’s 3D optical microscopes measure surface roughness in seconds with subnanometer repeatability and accuracy over large fields of view to quantify microscale finish, radius of curvature variations, scratches, and other defects that affect the tribological behavior of implants. The result is maximized lifetime for a wide variety of implants, from hip balls and cups to knees, elbows, and spinal implants.
