Kupros Cu29 V2 Makes Conductive Filament Practical for Desktop 3D Printers

Copper prices have spent much of 2026 at all-time highs. That has put pressure on every industry that depends on the metal, from construction to consumer electronics. Additive manufacturing is no exception. But one Indiana-based company sees the situation differently. For Kupros, the copper crunch is a proof of concept.

What Cu29 V2 Is

Cu29 is an all-metal, conductive filament engineered to run on standard desktop FFF and FDM printers. The first generation proved it could print conductive traces. The second generation, launched last month, addresses the actual problems engineers hit when they try to use it: workflow friction, inconsistent extrusion, and the fact that most users had no clear recipe for going from a design file to a working circuit.

Kupros put an initial batch of 90 kilograms of Cu29 V2 into the market. It sold out quickly, which tells you there is real demand from people who have already been through the V1 learning curve and want more.

Beyond Traces: Embedded Electronics

The bigger announcement is the patent-pending workflow Kupros is developing for embedded electronics. The idea is to place conductive pathways and electronic components inside a standard FDM print as it builds, rather than adding wiring after the fact. Applications include conformal antennas, sensors, and anything else that benefits from having circuitry integrated directly into a part's structure.

Kupros CEO Ian Ramsdell, a former Navy officer, put it plainly: "V1 proved that this was possible. Cu29 V2 is about making it easier for engineers to actually deploy. We spent the last year printing, breaking things, rebuilding them, listening to our early adopters, and understanding where the workflow created friction."

He goes further: "If you can introduce conductive pathways and electronic components directly during a standard FDM/FFF workflow, the printer stops being only a mechanical manufacturing system. It begins becoming an electronics manufacturing platform."

Military Interest Is Real

Kupros has sent Cu29-enabled sensor test articles to Oak Ridge National Laboratory for evaluation. But the military angle is the one that makes this story different from a standard filament launch. The US Army DEVCOM Armaments Center recently tested remote 3D printing for drone electronics repair during the Valiant Shield exercise in the Indo-Pacific. Marines involved in the project told the team they want an automated solution for all-in-one electronics maintenance diagnostics and 3D-printed repair components that can survive rugged field conditions.

The private-sector partner on that project, Sciperio, is the sister company to nScrypt, which has already worked with Cu29. That makes Kupros a natural fit for the next phase of military electronics-on-demand research.

Education as a Long-Term Market

Ramsdell also sees the education market as a strong long-term fit. Getting K-12 and college students interested in manufacturing is a national priority, and electronics are what get young people engaged. Giving students a way to print functioning circuits on the same machine they use for mechanical parts could help bridge the gap between hobbyist curiosity and professional engineering skills.

Copper prices may keep climbing. But if Kupros can make desktop conductive printing reliable enough for real engineering workflows, the cost of the material matters less than the speed and flexibility it delivers.
