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.

      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.

    All they are doing is working on acoustics…..just bs marketing hype.

    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!!

      whats the deal with the random all caps? is it code? AND ALL ALREADY EXTREME ANY AND FAR HAS BEEN WELL PROVEN..guess not.

    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.

      I certainly hope not. Would love to put a wager on this. Now is a great time to buy!

Bettinardi signs Eddie Pepperell



Eddie Pepperell is a singular quantity in to world of golf, so it’s not surprising that the Englishman has taken a unique route to becoming a Bettinardi staffer.

20 months ago, the two-time European Tour winner walked into Core Golf in Thame, Oxfordshire, and bought four putters, including a Bettinardi Studio Stock No. 8.

Pepperell, who jumped from No. 513 to No. 38 in the OWGR since putting the Bettinardi in play in April 2017, won’t have to pay for his putters any more. He joins the likes Francesco Molinari, Haotong Li, and Matt Kuchar as a Bettinardi staffer, the company announced the today.

“I’ve tried a number of putters and time and again, it’s the one model I keep coming back to.” said Eddie. “Positively I won’t have to buy a Bettinardi putter again, but having bought four putters from Core Golf I’m just hoping I haven’t put them of business as a result!” he added.

It was after Pepperell’s British Masters triumph in October that negotiations to bring him on board began in earnest.

“Once Eddie stayed ahead of a strong field at the British Masters to win his second Tour title of the year with a Bettinardi putter, we decided to reopen negotiations and we’re delighted with the outcome. It means that we now have another top 50 player in the world playing Bettinardi putters…” said Executive Vice President, Sam Bettinardi.

Here are the specs for his Studio Stock No. 8, courtesy of Bettinardi, which also provided the photos below of Pepperell’s putter (pre rust).

Material: Mild Carbon Steel
Finish: Mercury Gray PVD Finish
Face Milling: F.I.T. Face
Weight: 358 grams
Length: 33.25”
Lie: 71 degrees
Loft: 3 degrees

Miura offers fully assembled custom club e-commerce service



Miura Golf has announced that the company now offers fully assembled custom clubs direct to consumers through its website.

The new e-commerce platform was launched over Thanksgiving weekend, and it allows golfers to build an entire set of clubs custom to their preference. Golfers can choose from 10 different types of irons and custom make their club by choosing between different head, shaft and grip options. As well as the irons, Miura also provides golfers with the opportunity to custom make their driving irons, wedges and putter.

For Miura’s premium club, the MC-501 Chrome (4-iron-PW), customers have the choice between eight different heads, 13 shafts, and 14 grips.

Speaking on the new service, Miura Golf President Hoyt McGarity stated

“We are committed to introducing more golfers to the pure pleasure of hitting a Miura club. With’s new e-commerce capability, it has never been easier for golfers to have such direct access to Miura products.”

Lawrence Place, CFO, spoke to the target consumer for the fully assembled custom club offerings

“ is primarily for someone who already knows his/her specs or doesn’t have easy access to an authorized dealer. Our eCommerce offering is not intended to replace a full fitting at an authorized dealer, as we still believe that this is the best way to fit into a set of Miura’s.”

While long-time Miura enthusiasts may be wondering why the company chose this route now, it seems the answer is simple economics: demand.

On that subject, Will Miele, North America Sales Manager, said

“At this point, we wanted to be able to fulfill the demand for consumers who did not have an option to order full built sets of Miura products. So this phase one release gives golfers, who have their specs, the opportunity to go online and place a custom order. We highly recommend golfers seek out Miura dealers in their area through our dealer locator on our website and get properly fit.

“As we develop our website we will be adding features that will help consumers who cannot get to a local dealer a way to narrow down their options for better performance.”

The most expensive custom made iron options begin at $1,960, while the most affordable options start at $1,350. The custom clubs are available now at
