How Bryson DeChambeau used 3D printed titanium irons to win the Open (and what it means for golf technology)
The sight of Bryson DeChambeau hoisting the claret jug in victory after his stellar performance at the Open was more than just a victory for the golfer. This is a landmark victory Additive Manufacturing (AM)specifically Metal 3D printingjoining the elite echelon of professional golf. Under pressure from Royal Troon, behind his incredible distance control and precision was a series of revolutionary 3D printed ironpushing the boundaries of club design and manufacturing. Let’s break down this fascinating tech story.
Breaking the rules: The rise of custom 3D printed irons
Bryson is known for his physics-driven approach and relentless pursuit of optimization (“DeChambeauing” equipment), but he struggled with traditional forged irons. His pursuit of extreme forgiveness, perfectly optimized center of gravity (CG) position and unique styling led him (and his equipment company at the time, Cobra Golf) towards Selective Laser Melting (SLM) – Advanced metal 3D printing process.
Traditional wrought iron involves pounding a heated blank of metal into shape and then machining the cavity. This limits design freedom – complex internal structures and precise mass placement are very difficult or impossible. SLM turns this on its head. High-power lasers carefully melt ultrafine metal powders (in this case, 17-4 stainless steellater iterations merged Titanium alloy), build the iron head layer layer by layer.
Why SLM is a game changer:
- Unprecedented quality optimization: Bryson’s clubs feature dense tungsten components embedded in a lattice-like structure. SLM allows Cobra’s engineers to place precise amounts of tungsten exactly Where it’s needed – the clubhead is extremely low and forward. This dramatically lowers the center of gravity and increases the moment of inertia (MOI), providing explosive ball speed and forgiveness on off-center hits.
- Radical shaping: cavity back "aviation jet" (after "Bridger") design combines deep cavity recesses with unique geometry optimized for aerodynamics. Machining this shape from a solid blank is extremely costly and technically challenging. SLM makes this aerodynamic efficiency a reality.
- Ultimate customization: Each header can be processed individually. Mass distribution, wall thickness, internal structure – all are precisely customized to Bryson’s requirements based on forensic performance data. This level of custom design is unattainable in mass production.
- Rapid Prototyping Corridor: This is crucial. Development cycles accelerated dramatically. Cobra can design, print, test, analyze, redesign and reprint prototype iterations in days instead of weeks or months. This rapid iteration facilitated the intense optimization required by DeChambeau.

SLM process focus: More than just pressing print
Manufacturing parts like Bryson irons requires advanced equipment and expertise:
- Material: Mainly 17-4 stainless steel powder. Precise alloy composition control is critical for strength and consistency.
- printer: Industrial grade SLM/ILM machines Utilize high power lasers (200W to 1kW+).
- process: Apply a thin layer of metal powder. The laser scans the cross-section and selectively melts the powder particles based on the digital model, bonding them to the underlying layer. Thousands of floors were built successively.
- Support structure: Required for overhang features and removed after printing.
- Key post-processing: The original printhead was far from complete.
- Precision machining: The face, hosel, grooves and key joints are all CNC machined to precise tolerances. There’s no compromise on performance and feel.
- Heat treatment: Essential for achieving final metallurgical properties (hardness, strength).
- Surface treatment:Yujia smoothes, polishes, and coats (like the signature copper plating on Bryson Cobra irons) to satisfy aesthetics and minimize drag.

Beyond Distance: Aerodynamic Advantages
While the ultra-low center of gravity improves launch conditions (low spin, high launch), DeChambeau and his team are known for their intense focus. aerodynamics. A CAD-driven design process powered by 3D printing creates explicitly modeled cavity shapes to reduce drag throughout the swing, especially at high speeds, which is critical to Bryson’s aggressive transition and powerful release.
These esoteric shapes play a vital role. Traditional cavity backs create turbulence as air flows over and around them during the downswing. By carefully sculpting smooth internal channels and geometric turbulators, Bryson’s clubs gain valuable MPH clubhead speed at impact, converting power into usable distance. These precise airflow paths can only be achieved with SLM. (Designing for fluid dynamics?

The testing debate (and why Bryson’s club is legal)
Of course, clubs that push boundaries face scrutiny. DeChambeau has publicly discussed his club design journey, including comments from Cobra CEO Bob Philion: "causing harm to individuals" At Bryson’s inference early prototypes were "nonsense." What’s more, Cobra works closely with the USGA and R&A to ensure each prototype and final iteration complies with equipment rules.
Key guarantees:
- Material: 17-4 Steel and titanium alloy powders comply with permitted material parameters.
