“Cobra's 3D-printed Agera, a lightweight metal-lattice high-MOI mallet with an aerospace-grade aluminum face insert and LA Golf's descending-loft face; also comes in a reduced-size RS and counterbalanced armlock version. Announced March 2023, redesigned for 2024, and still Cobra's current flagship 3D-printed mallet as of 2026 — not a discontinued or placeholder SKU.”

In 2021 Cobra became one of the first major OEMs to sell 3D-printed putters at retail, and the Agera was the flagship mallet. Built with HP's Multi Jet Fusion process, its head sandwiches a nylon lattice 'cartridge' — about half the mass of aluminum — between steel, aluminum and tungsten, letting Cobra push freed weight to the perimeter for one of the highest MOI figures in Cobra's putter history. It pairs that with a SIK-designed face (later via LA Golf) using Descending Loft Technology: four loft zones, 4° at top to 1° at bottom, reducing skid so the ball rolls truer regardless of strike height. Cobra redesigned the line in 2024; the Agera remains its current flagship mallet, also offered as a reduced-size RS and armlock version.

Not a cult classic — it's a current, actively-sold product rather than something hunted on the secondary market — but it's genuinely notable as a manufacturing first: HP and Cobra's joint press release and multiple 2021 reviews (Golf.com, GolfWRX, Today's Golfer) all frame the King 3D Printed line as the first 3D-printed putter family a major OEM sold at mainstream retail rather than as a limited tour exclusive.

Golfers who miss the putter face inconsistently and want maximum stability over feel and feedback; the size and weighting suit a straight-back-straight-through, face-balanced stroke rather than an arced stroke looking for a compact blade.

• Cobra partnered with HP and Parmatech to build it using HP's Multi Jet Fusion process; the nylon lattice cartridge weighs roughly half what the same-volume aluminum would.
• It followed a more expensive, more limited 2020 HP Metal Jet putter (the King Supersport-35) — Agera and Supernova were the 2021 push to bring the tech to mainstream retail pricing (~$349).
• Face technology (originally branded SIK, now delivered via LA Golf) uses four descending loft zones — 4°, 3°, 2°, 1° from top to bottom — to reduce skid on strikes above or below center.
• Redesigned for 2024 with an RS (reduced size) version and a counterbalanced armlock model added to the family.
• Reviewers highlighted its size and 'futuristic' look, with the lattice structure visibly poking out the sides at address, as much a design statement as a performance one.

Launched in 2021 as part of Cobra's first retail 3D Printed family (alongside the Nova/Supernova mallet and King Vintage blade series), following a more limited 2020 HP Metal Jet run of the King Supersport-35. Redesigned for 2024 with a reduced RS version and an armlock counterbalanced model added — still Cobra's current flagship 3D-printed mallet as of 2026, not a discontinued placeholder SKU.

As a still-current model (not discontinued), used copies are scarce and don't discount much — expect roughly $200-280 for a clean used Agera against a $349 MSRP, mostly from golfers trading up to the RS or armlock variant rather than the putter underperforming.
