Callaway redesigns Odyssey R-Ball Prototype using GE’s additive manufacturing
Callaway has announced the company has signed a consultancy agreement with GE Additive’s AddWorks team, with the aim of improving its equipment through the potential of additive manufacturing. According to GE Additive’s website, additive manufacturing is a process that creates a physical object from digital design, enabling the creation of lighter, stronger parts and systems.
What does this mean for Callaway’s equipment?
The opening project from the agreement is a redesigned Odyssey R-Ball Prototype putter head. Callaway originally developed the Odyssey R-Ball Prototype as a tour preferred model in Japan, which consisted of removing the front ball from the original 2-ball design. Callaway, through additive manufacturing, has optimized the acoustics of the putter while retaining the preferred shape and performance.

Brad Rice, director – R&D, Advanced Engineering at Callaway, speaking about the process, stressed that the use of additive manufacturing is the future to the production of equipment in the game of golf, stating
“Additive manufacturing is a new tool; which is quickly going beyond the aspirational phase, and into the functionalization phase of the technology. Callaway needs to learn how to use this tool well because it is inevitable that 3D-Printing of production parts is going to happen – it is the production method of the future.”
So just how has Callaway and GE Additive collaborated to create the ideal acoustics on the Odyssey R-Ball Prototype putter head? Well, the answer is by adding geometry that made it difficult for conventional casting methods, which you can get a feel for in this short video.
For the Odyssey Prototype putter to retain its optimal design and shape while altering the acoustic signature of the putter head, Callaway and GE Additive’s AddWorks’ design and engineering teams implemented additive manufacturing through the following process:
- AddWorks provided guidance to Callaway, based on decades of additive design background spanning several industries.
- The team refined existing designs to the build direction to ensure all features were self-supported or easily supported during the build. The AddWorks team designed supports for thermal stresses and overhang constraints.
- Topology optimization was used in conjunction with acoustical mapping to create the optimal design.
According to GE Additive AddWorks general manager, Chris Schuppe, additive manufacturing is a method which we are going to be hearing of a lot down the line, and he is expecting this to be the first of many collaborations with Callaway
“We’re taking away many new learnings from our first project together, especially around aesthetics. We have also used additive technology to create an acoustic map, which is certainly a first for us. We’re looking forward to driving more successful projects with Callaway, as they continue their additive journey.”
What the future holds for Callaway’s products through the use of additive manufacturing remains to be seen. However, the company’s bold stance on the potential of the process enhancing their equipment could be telling.

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

Name every set of irons you’ve owned – GolfWRXers discuss
In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.
@Lamosteve began:
Can you name every set of irons you’ve owned? Here’s mine
Spalding Dots
Spalding Eclipse
Ram Lazer FX
Lynx Parallax
Mizuno EZ Comp
Ben Hogans
Cleveland CG Red
Taylor Made R9s
PING i20
PING iE1

Our members in the forum have been offering up their own collections. Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

Yep.
Callaway is King of this. Boeing, Lamborghini, now GE. They partner with companies that can add credibility to their marketing story.

GE will attempt to “engineer out” the unnecessary material and make it ring like a bell… how low can you go using high tech capability?!! Pa thetic US technology usage.

EBM or Electronic Beam Manufacturing is for the most part a bought up technology from a Swedish company called Arcam, that is now a part of GE. It’s actually fun to see 3D-printing technologies getting a wider audience. Rapid prototyping might soon become rapid(and local) production! Now wouldn’t that be a thing Bob? Where all you’re golfclubs is not produced in Taiwan but in the neighbouring town? Supporting local business and less shipping?

Has anyone ever complained about the sound the putter makes? If the sound sucks, the design probably sucks. Start over.

Geerhead duffers want a good sounding putter because that’s all they look forward to… a ding sound…!

So, the short story is they couldn’t figure out how to do this in-house, called a contractor, and they’re spinning it as competence.
Nice story, bros.
Maybe they will start making clubs that don’t have high failure rates. That’d be nice.

That’s called patent infringement, libtard. You don’t just get to take another’s ideas and processes and make them your own.

First, Libtard? Grow up.
Second, patent infringement? I’m guessing that your use of “libtard” probably precludes a college degree, so maybe, just maybe, leave the litigation to those qualified.
Third, you clearly weren’t replying to the above, so I suggest you brush up on your interwebbing, Señor AOL…
Finally, I don’t get the American fascination with insults and someone’s political views. I thought America was “land of the free” and such… you really are an intolerant bunch.

Callaway AND many other manufacturers of ALL kinds of products should have ALREADY been using 3D printing!!! The EXTREME amount of savings in designing ANY proto type is and the ability refine their products is very flexible AND inexpensive!!
Its about time, they are FAR behind in using this tech that is HAS BEEN WELL PROVEN!!

Cool story. I do think additive, 3-D, multi-material, etc. will be the future for some golf clubs. Article would have been better if Callaway had released some pictures of the final product or some information about how they can actually apply this to a product.

GE will be bankrupt in a few weeks. Callaway would be smart to buy this unit now.
