Takeaways from hitting Cobra’s secret 3D-printed Tour prototypes

While visiting Cobra HQ to film our 3DP feature, I was able to spend some time hitting prototype irons built for a few different Cobra staff players on the PGA and LPGA Tours.

This is probably the most unique feature of Cobra’s 3DP process. They can make one-of-one sets for Tour players in just weeks, rather than retooling a head for a new forging, which would take months. This turnaround ability has vaulted Cobra to the top of the list for free agents seeking a new set of irons, and it’s likely we’ll start seeing more players on major tours switch to their own 3DP customs.

Let’s break down my favorites from testing at HQ.

Max Homa’s solid MBs

Max Homa signing with Cobra was big news, and Max has repeatedly said that the process of building his own 3DP iron was one of the reasons he was so excited to sign with Cobra. He was a big fan of the standard King MB forged irons that Cobra was making, and a lot of what he did with his 3DP.MH irons (which you have also seen in some images as the 3DP.MB.s) were to emulate the feeling he got from those, while adding a bit of forgiveness thanks to the increased mass properties of the 3DP heads. He also adds a touch of offset to his set compared to the standard forged offerings. The biggest difference for Max? He doesn’t have an internal lattice system with his irons. He chose to create his set as a solid-printed set that gives him the feel he’s been looking for, matching the irons he’s played most of his life. The advantage for him? He still gets the shape, visual package and performance he’s after to his exact specifications.

Rickie Fowler’s 3DP King Tour Love

Rickie Fowler has an interesting equipment story on tour. He’s an unabashed golfer who wants to use the best tools for his game, and over the last several years, he has made a few changes you might not expect from a Tour player. He started playing AeroTech graphite iron shafts and a “player’s distance” iron in the Cobra King Tours. The combination has been great for Rickie, and he’s been nothing but complimentary of the more forgiving build. When Cobra introduced him to the 3DP program, he really didn’t want to change much from the King Tour heads. So the 3DP.RF (which you’ll also see in photos as the 3DP.KT for King Tour) is based heavily on the King Tour, but again, with better mass properties that increase the MOI of the head. His irons are a combination of the King Tour and the 3DP Tour. Offset from the King Tour, MOI from the 3DP Tour, a touch higher toe height compared to the 3DP Tour and the coolest part of his build is they didn’t add any tungsten to Rickie’s 3DP irons. They achieved a higher MOI design with just the internal lattice structure. The combination of which allows them to hit Rickie’s preferred launch properties.

The toughest switch: Lexi Thompson

Lexi Thompson likes the weirdest iron ever — the Cobra S2 Forged. This is an iron that came out over a decade ago, and she has been so in love with it that she still has them in the bag. The problem? Cobra doesn’t make the iron anymore, and they don’t even have a stash. But there’s a simple fix: 3D printing. I actually think this is where Cobra’s 3D-printing ability really shines. They can take a player like Lexi Thompson and give her the exact iron shape and visual that she wants with more performance. In very simple terms, they can scan the old S2 Forged, then take that model into their new software and create an internal lattice structure that gives her a higher MOI design with a bit more ball speed, while keeping the exact offset, sole and loft package she has desired for years.
