DeChambeau's 3D-printed iron sparks Masters post-round questions
Bryson DeChambeau was puzzled by a post-round question about his USGA-approved 3D-printed 5 iron after posting a 4-over 76 in the Masters’ first round. He explained the club’s curved face is designed to straighten some mis-hits and detailed the lengthy approval process (print time plus finishing) required by the USGA. He used the club on the seventh hole and said it was “great,” but his round slipped with a bunker mishap and a triple bogey on the 11th, leaving him nine strokes behind leaders after day one.
