3D Printed Steel ConstructionEach 3DP Tour iron is produced using a full 3D printing process with 316 stainless steel. This approach removes the limitations of forging and casting, allowing COBRA engineers to control internal structure and mass placement with far greater precision. The result is a head that delivers consistent performance from club to club, while unlocking design characteristics that aren’t achievable through traditional manufacturing.Forgiving Players Blade ShapeThe external shape of the 3DP Tour is compact and refined, similar in size to a traditional player's iron. Internally, however, 3D printing allows the mass properties to behave more like a game-improvement design. By combining a high moment of inertia with a low centre of gravity, the iron offers increased stability and forgiveness without losing the clean lines, minimal offset, and soft feel demanded by better players.Internal Lattice StructureAt the core of the 3DP Tour is a complex internal lattice structure. By transforming the interior of the blade, COBRA reduces overall head weight by approximately 33 percent. This discretionary weight is then redistributed to optimise centre of gravity placement, improve stability, and enhance feel, all while preserving the traditional blade profile at address.Extreme Forgiveness with Soft FeelThe internal lattice doesn’t just save weight. It also reinforces the structure of the face and topline, allowing stiffness and strength to be tuned precisely. This enables COBRA to fine-tune acoustics, producing a controlled, muted impact sound that translates directly into a softer, more responsive feel. Even on slight mishits, feedback remains composed rather than harsh.Tungsten WeightingUp to 100 grams of tungsten is positioned low in the heel and toe, using the weight freed up by the 3D printed lattice. This significant tungsten placement dramatically increases MOI for a blade-style iron, helping preserve ball speed and directional control. The result is a compact iron that offers forgiveness levels closer to a game-improvement model, without sacrificing precision or workability.On-Course PerformanceOn the course, the 3DP Tour delivers a controlled, penetrating flight with consistent launch and predictable spin. Centre strikes feel solid and precise, while slight misses retain more stability and distance than expected from a traditional player's iron. The head remains calm through impact, encouraging confident swings and reliable shot patterns, particularly under pressure.Who It SuitsThe 3DP Tour is ideal for golfers who value shape, feel, and feedback, but want more forgiveness than a conventional blade or players' cavity typically provides. It suits confident ball-strikers, competitive amateurs, and aspirational players who want modern consistency in a classic, compact form.Specifications Club Loft Lie Offset (mm) Length Dexterity 4i 21.5 ° 60.5 ° 3.0 38.75” RH / LH 5i 24.0 ° 61.0 ° 2.7 38.25” RH / LH 6i 27.0 ° 61.5 ° 2.4 37.75” RH / LH 7i 31.0 ° 62.0 ° 2.1 37.25” RH / LH 8i 35.0 ° 62.5 ° 2.0 36.75” RH / LH 9i 40.0 ° 63.0 ° 1.7 36.25” RH / LH PW 45.0 ° 63.5 ° 1.6 36.00” RH / LH Built In-House at Nine by NineEvery COBRA 3DP Tour iron set is assembled in-house at the Nine by Nine Golf workshop. Each club is built by a single master builder and finished to tour-level tolerances before dispatch. The focus is on accuracy and consistency, so every club in the set matches the specification you ordered.
