Cobra has introduced the Limit3d Irons, priced at $2,999.99 for a 4-PW set with KBS Tour $-Taper shafts. These irons are 3D printed using 316L stainless steel with internal tungsten weights, and will be available starting June 7. The target audience for these irons are golfers with deep pockets who desire an iron that appears like a muscleback blade but performs like a game-improvement iron.
Traditionally, golf club heads are made through either a casting or forging process. However, with the Limit3d irons, Cobra has ventured into 3D printing, offering a new perspective on golf club manufacturing. The innovative 3D printing process allows for intricate designs that may not be possible through casting or forging methods. Previously, Cobra utilized 3D printing for putters and wedges, and now they are applying this technology to irons with the Limit3d series.
The Limit3d irons are based on the design of the King Tour irons played by professional golfer Rickie Fowler. These irons feature a compact blade length, a touch of offset, and a thin topline. The 3D printing process involves a computer-controlled DMLS technique that layers 316L stainless steel powder to create each clubhead. The internal lattice structure of the irons reduces the weight in the central area by about 100 grams, allowing for added tungsten weights for stability.
Cobra engineers chose an intricate lattice structure for the Limit3d irons, as it provides strength while reducing central weight significantly. The addition of tungsten weights in the heel and toe areas enhances the moment of inertia (MOI), making the irons more forgiving on off-center hits. The 3D-printed elements of the irons, such as the hitting area, back, and body structures, are made using 316L stainless steel powder.
The Limit3d irons maintain similar aesthetics to the King Tour irons at address, but offer improved stability and forgiveness. Cobra claims that the Limit3d irons provide approximately 3 mph more ball speed compared to the King Tour irons, resulting in about 5 extra yards of distance. Despite the premium price tag of $2,999.99, Cobra notes that the cost of 3D printing metal is decreasing, hinting at possibilities for more affordable options in the future.
The Limit3d irons showcase the potential of Cobra’s design capabilities and new manufacturing technologies. With only 500 sets available worldwide, these irons offer a glimpse into the future of golf club innovation. Much like a Formula One car demonstrates cutting-edge technology in the automotive industry, the Limit3d irons represent the forefront of golf club design and manufacturing processes.
