Georgia Tech Biomedical engineering undergrad designed an adjustable golf putter using an advanced metal-depositing 3D printer. 

For many golfers, pros and weekend warriors alike, their trusty old putter can be like a reliable friend — comfortable, predictable, solid.  The thought of changing it? Well, let’s not even go there.

Yet, an undergraduate in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University has been working on a project that could make it easier to experiment with putter characteristics. The project’s goal is to allow golfers to adjust parts of their club to find a better stroke, rather than having to buy a new club. It also could help equipment manufacturers reimagine their prototyping and design process.

For the last year and a half, Caroline Means has been designing a putter...
