Cobra is giving golfers more opportunities to fit into their groundbreaking 3D-printed irons.
Joining the 3DP Tour irons, which are the first commercially available 3D-printed irons in the game, Cobra is announcing new 3DP MB and 3DP X irons, adding two new shapes created from the 3D-printing technology.
“We’re excited to offer these two new innovative iron models that build on the tremendous success of our 3DP Tour irons,” said Ryan Roach, Director of Innovation at Cobra Puma Golf. “With the addition of the MB and X, we now have a 3D-printed model that can fit the vast majority of players, allowing just about any golfer to benefit from the performance advantages of 3D printing technology.”
Both of the new irons feature the same internal lattice structure as the 3DP Tour irons, which are in the bags of several Cobra Tour staffers, including Max Homa. Gary Woodland used a set of prototype LIMT3D.MB irons last spring on the PGA Tour.
The internal lattice allows Cobra designers to reposition weight low and toward the perimeter of the clubhead using tungsten to create ultra-high MOI designs from more compact shapes.

What’s actually new with Cobra 3DP MB and X irons — and why you should care
A muscleback that plays like something much bigger
The 3DP Tour irons already pushed the idea of how much forgiveness you can pack into a more compact iron shape. The new 3DP MB irons take that a whole step further. The MBs have an internal lattice core structure surrounded by solid 3DP-printed steel and two massive tungsten weights in the toe and the heel to concentrate weight low and in the perimeter of the head.
“We’ve kind of discovered this little niche category of a blade that’s forgiving, and there’s not really anything that exists out there in the market today like that,” Cobra Senior Product Line Manager Caitlin Farley told GOLF. “So we took a blade shape, and we do a lot of cool internal stuff, like 3D-printed latticing, that allows us to distribute weight more efficiently in the clubhead and help create higher MOI in a small shape.”
Farley said Cobra tested both versions of the MB with and without internal latticing and found tour staffers preferred the weighting with the lattice structure. The shape is based on Max Homa’s initial set of King MB irons to begin last season, which were 3D-printed without a lattice to be slightly more compact and have more offset than the standard King MB.
A better feeling and performing game improvement iron
With the 3DP X, Cobra has taken the profile of the King Tec X iron and created a 3D-printed design that uses a single-piece construction rather than a face insert like other products in the category.
That means the 3DP X is going to feel much better than other game-improvement irons, and with the lattice and tungsten weighting, it’s going to produce faster ball speeds and spin to keep the ball in the air.
3DP Flow sets
With Cobra now the first company to offer a full range of 3D-printed irons, they’re also making it simple and easy to combo all three sets together.
While the three sets have progressively stronger lofts from the MB to the X, because of the lattice structure and low tungsten weighting, spin is retained much better when moving from weaker to stronger lofted irons.
“You’re gonna get really consistent numbers across all the models, depending on your swing speed,” Farley said. “So that lends itself nicely to be able to combo those sets pretty seamlessly, using the existing specs.”
Most players will be able to move between the three models within a set while making minimal, if any, changes to lofts. If changes are needed, the material is still soft enough, like forged clubs, to make adjustments.
The 2026 Cobra 3DP Iron lineup
Joining the existing 3DP Tour irons, Cobra’s 3DP iron lineup now includes models in both the player’s, player’s distance and game-improvement categories.
3DP MB irons
What is it: Based on the shaping of the King MB irons, the 3DP MB irons are 3D-printed with an internal lattice core and tungsten weighting to boost heel-toe stability and increase MOI. The 3DP MBs have a slightly thinner topline and a touch more offset than the King MB, similar to Max Homa’s personal set. Because of the tungsten weighting, 3DP MBs have a lower CG than typical blades and launch higher. It will also be a touch faster, but consistent on mishits.
Who it’s for: With a traditional loft package and compact profile, this iron has a huge playability range given its forgiveness. This iron could be used by any player with speed who isn’t afraid of a compact shape and wants to retain maximum workability. You will see this iron on the PGA Tour and potentially in your 10-handicap buddy’s bag.
3DP Tour irons (Already available)
Can Cobra’s 3D Printing completely change the irons market?
What is it: Cobra’s initial 3DP offering takes a player’s distance shape — the King Tour specifically — and supercharges it with tungsten weighting and the internal lattice.
Who it’s for: The 3DP Tour can be played by better players or game-improvement players alike, but typically falls into the player’s distance category with slightly stronger lofts and a more compact footprint. This could also serve as a long-iron swap in a combo set of MBs or short-iron swap in a combo set with the Xs.
3DP X irons
What is it: The 3DP X iron is going to be one of the most forgiving game-improvement irons on the market. Thanks to the 3D-printed lattice and large tungsten weights in the toe and hosel, it’s going to retain spin too. The X comes from the same profile as the King Tec X, with slightly weakened lofts to achieve higher peak heights and increased stopping power.
Who it’s for: The 3DP X is going to serve the game-improvement player as an ultraforgiveness model that still retains speed. Rickie Fowler is also testing a 3DP X 4-iron as his driving iron, proving the versatility of the club.
My take: Cobra has covered almost everyone with 3 models
These days, you see a lot of OEMs trying to cover every player type with several different models of irons, all of varying shapes and sizes. What Cobra is doing is throwing a wide net over those player types with just three iron shapes. It works because each of them is so much more playable than other irons in its size class.
During my fitting for the new 3DP irons, I was surprised by just how compact the 3DP MB was compared to the typical players’ cavity backs I’m used to playing. Yet they were extraordinarily easy to hit and get into the air.
I was expecting to play the MBs through the 6-iron and then move to the larger Tour or X models. But to my surprise, I easily hit my speed numbers with the 5-iron without having to work at it. The MB 4-iron (and 3-iron too) were shockingly easy to hit high, towering shots, too, but I didn’t quite have the speed. I broke my MB set with a 3DP Tour 4-iron.
The level of ease with which I could swing a clubhead as small as the MB and have the ball do exactly what I wanted it to was shocking.
It was just as equally shocking when I hit the 3DP X for the first time and saw that the ball was shooting out flat like a rocket, but it was spinning much more than other irons in its class. Not to mention the sound was much improved from typical game-improvement irons.
Cobra made a splash when it first introduced the 3DP Tour, but now, the two new models might blow the cover off 3D-printed irons.
