Cobra Unveils 3DP MB and 3DP X 3D-Printed Irons

Cobra introduced two new iron models for 2026 built around additive manufacturing and internal lattice engineering, marking a clearer shift from prototype use of 3D printing into serialized golf-club production. The 3DP MB and 3DP X are produced using direct metal laser sintering in 316L stainless steel and incorporate complex lattice cores enabled by 3D printing to control sound, feel, and mass distribution in ways conventional cast or forged processes cannot.

The 3DP MB targets better players and draws inspiration from a Max Homa prototype. It features a thinner topline and tungsten weighting positioned to increase stability while maintaining a compact look. The 3DP X is aimed at mid-handicap players, trading some compactness for higher launch and added forgiveness. Cobra achieves these performance differences primarily by shifting tungsten mass within the lattice cores and by tailoring the interior geometry to allow very thin face constructions that offer both an enhanced feel and a wider effective hitting area.

Beyond cosmetics and player targeting, the real story for the 3D-printing and sporting-equipment communities is the way internal lattices are being exploited as functional design elements. Using DMLS in 316L stainless steel lets engineers place lattice structure where needed to tune acoustics and vibration, route mass to precise locations, and support thin external shells that would be difficult or impossible with traditional manufacturing. That capability opens a path for designers to treat internal voids as performance levers rather than manufacturing constraints.

Commercially, Cobra priced six-piece sets at an RRP of $1,980. The company began pre-sales on January 6, with retail availability following on January 9. The pricing positions the irons as a premium offering where additive manufacturing is a deliberate feature rather than a novelty.

For designers and makers, Cobra’s rollout underscores practical lessons: DMLS in 316L can scale beyond prototypes into finished consumer products, lattice cores can be tuned for acoustics and structural support, and strategic tungsten placement complements internal geometry to meet distinct player needs. Expect to see more sporting goods explore internal lattices and metal additive processes as manufacturers chase nuanced performance and feel that conventional methods struggle to deliver.
