This is achieved through the strategic placement of weights in heel and toe regions, the fabrication of lattice structures within the club head body, and the integration of reinforcement features and protective coatings. The inventive concept also includes computer-aided design modules for designing lattice structures and weight distributions, and 3D printing modules for fabricating the designed club head.

Novelty and Inventive Step

The new claims introduce novel and non-obvious solutions for optimizing weight distribution, enhancing durability, and providing customizable structural properties in golf club heads manufactured via additive manufacturing. These solutions overcome the limitations of traditional manufacturing methods and provide significant improvements over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying lattice structure geometries, weight distributions, and reinforcement features to achieve specific performance characteristics. Additionally, the inventive concept could be adapted for use in other sports equipment, such as tennis rackets or baseball bats.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the golf industry, where customized golf clubs with optimized performance characteristics are in high demand. The target market includes professional and amateur golfers seeking high-performance golf clubs with improved accuracy and distance.
