Inside Story

Rapid Precision Prototyping Program Speeds Medtech Product Development

Rapid prototyping technologies play an important role in supporting new product development (NPD) by companies that are working to bring novel and innovative products to market. But in advanced industries where products often make use of multiple technologies, and where meeting a part’s exacting tolerances is essential, speed without precision is rarely enough. In such advanced manufacturing—including the medical device and surgical robotics industries — the ability to produce high-precision prototypes early in the development cycle can be critical for meeting design expectations and bringing finished products to market efficiently.
