The Cobra 3DP MB irons are part of an extensive range featuring the latest 3D printed muscle back design launched in early 2026.
Released together with the 3DP X ironsand joins the previously launched 3DP tour model, the MB design is a compact blade aimed at better players and low handicap golfers.
The new MB irons are fully 3D printed from 316 stainless steel with internal lattice structures and heavy tungsten weighting for added stability and forgiveness.
The 3D printed irons build on the King MB design, but feature a noticeably thinner topline and more offset for a clean, blade-like appearance at address.
Advantages and disadvantages
✅ Blade-like address look with a very compact traditional MB shape that will appeal to better players and purists
✅ Much higher forgiveness than a typical muscleback thanks to the internal grid and tungsten, better maintaining ball speed and distance on minor mishits
✅ Soft, ‘forged’ feel and tuned acoustics, despite being stainless and 3D printed, reported as very solid and responsive on impact
✅ Consistent launch and distance control across the face, aimed at single-digit handicaps and elite ballplayers who still want some built-in help
❌ Very high price, around $1,980 for a set of six clubs with standard steel shafts, putting them at the extremely premium end of the hardware market
❌ Still a true head profile: compact head, thin topline and minimal offset make them demanding compared to player distance or caveback designs
❌ The stainless steel 3D printed construction is unconventional, so some golfers may be skeptical of classic forged carbon steel when it comes to feel and long-term perception
Specifications and design of Cobra 3DP MB irons
Cobra 3DP MB irons are compact, tour-inspired musclebacks built for experienced ball strikers who still want modern forgiveness and stability hidden in a traditional blade profile.
Designed with direct tour input from players like Max Homa and Gary Woodland, they take visual cues from the popular ones King MB but refine the proportions for a sleeker look.
The 3DP MB uses a 3D-printed one-piece 316 stainless steel shell with an internal grille core allowing Cobra to maintain a classic muscleback exterior while transferring mass to the heel and toe via integrated tungsten.
The MB has a slightly thinner topline and slightly more offset than the standard King MB, creating a clean, blade-like appearance at address that better players prefer, but with subtly more playability.
The grille core is tuned to control acoustics, providing a soft, forged impact feel despite the stainless steel construction, and also reinforces the structure to give the clubhead a firm feel on center and off-center hits.
Additional tungsten mass in the heel and toe increases the moment of inertia in what is still a very compact blade chassis, making the 3DP MB one of the most forgiving true muscleback style irons on the market today.
The 3DP MB irons are available in 4 iron (24 degrees) to Gap Wedge (50 degrees).
Cobra 3DP MB Review: Are They Any Good?
The MB is aimed at low handicap golfers and stronger ball players, but thanks to its internal 3D grid weighting it is playable up to a handicap of around 10 and therefore much more accessible than traditional blades.
The MB’s compact head, narrow sole and thin topline provide precise turf interaction, traditional launch characteristics and the kind of workability the blades are known for.
But Cobra has managed to add extra stability to this version compared to conventional musclebacks for one of the most impressive newcomers for 2026.
