Cobra 3DP MB & 3DP X Irons Join Expanded 3D-Printed Range (Reviewed)

Cobra have expanded the ground-breaking 3D-printed irons line-up with two new models for 2026 – the 3DP MB and 3DP X irons.

The two new models are fully 3D printed from 316 stainless steel with internal lattice structures and heavy tungsten weighting for added stability and forgiveness.

The 3DP MB and 3DP X sit alongside the 3DP Tour model, giving three distinct profiles – a compact blade (MB), compact players cavity (Tour) and a larger, higher-launch game-improvement (X).

The MB targets better players wanting a traditional muscleback look with surprising playability, while the X model is a sleeker game-improvement option aimed at a much wider range of handicaps.

​Pros & Cons

✅ MB Blade has a compact, tour-inspired muscleback profile with thin topline and traditional shaping
✅ MB has more stability and ball‑speed retention on heel/toe strikes compared to classic forged blades
​✅ X has a larger profile, more offset and higher MOI and stability than the MB and Tour models
​✅ X is easy to launch with strong ball speeds across more of the face, suiting a wide handicap range
✅ Confidence‑inspiring shape of the X offers game‑improvement dimensions without being overly chunky
❌ MB is best for better players and mid–high handicappers may struggle versus a cavity‑back
❌ The larger head, extra offset and thicker topline of the X will not appeal to purists or players who prefer a classic blade look
❌ Premium price is a little off-putting

Cobra 3DP MB Irons Specs & Design

Cobra 3DP MB irons are compact, tour-inspired musclebacks built for accomplished ball-strikers who still want modern forgiveness and stability hidden inside a traditional blade profile.

They are designed with direct tour input from players like Max Homa and Gary Woodland and take visual cues from the popular King MB but refine the proportions for a sleeker look.

The 3DP MB uses a one-piece 3D-printed 316 stainless body with an internal lattice core that lets Cobra maintain a classic muscleback exterior while shifting mass to heel and toe via integrated tungsten.

The MB has a slightly thinner topline and a touch more offset than the standard King MB, producing a clean, blade-like appearance at address that better players prefer but with subtly more playability.

The lattice core is tuned to control acoustics, giving a soft, forged-like impact feel despite the stainless construction, and also stiffens the structure to keep the head feeling solid on centre and off-centre strikes.

Additional tungsten mass in the heel and toe raises MOI in what is still a very compact blade chassis, making the 3DP MB one of the most forgiving true muscleback-style irons currently on the market.

The 3DP MB irons are available in 4-iron (24 degrees) to Gap Wedge (50 degrees).

Cobra 3DP X Irons Specs & Design

Cobra 3DP X irons are the game-improvement entry in the 3D-printed family – opening up the series to a wide range of golfers.

The design uses the same stainless-steel and lattice-core concept of the MB and Tour models but in a larger, higher-launch models that is designed to help a wider spectrum of golfers hit it higher and straighter.

The X delivers the feel and solidity of the Tour and MB models but in a package that is far more forgiving on off-centre contact.

Like the MB, the X is fully 3D printed from 316 stainless steel and built as a one-piece head without a separate face insert, which is unusual in the game-improvement category where multi-material faces are common.​

The internal lattice structure is optimised for weight savings and support and backs up a thin face to preserve feel while allowing Cobra to push significant mass into the toe and hosel areas as discrete tungsten elements.​

The tungsten design is specifically engineered to drive MOI and overall stability higher than the MB and Tour heads, giving the X model more forgiveness and help on low-face or heel-toe misses.​

The 3DP X irons are available in 4-iron (20 degrees) to Gap Wedge (48 degrees).

Cobra 3DP MB & X Irons Review: Are they are good?

Cobra’s expanded 3D-Printed series is now complete with the launch of the two new 2026 models.

The MB is aimed at low-handicap golfers and stronger ball-strikers but, thanks to the internal 3D-lattice weighting, is playable up to around a 10 handicap and therefore far more accessible than traditional blades.​

The compact head, narrow sole and thin topline of the MB deliver precise turf interaction, traditional launch characteristics and the kind of workability blades are known for, but with extra stability versus conventional musclebacks.​

In the X, Cobra have keep the overall profile larger and with a slightly thicker topline than the MB for a more confidence-inspiring look – but the shaping is clean and sleek still compared to typical game-improvement irons.​
