Kupros Cu29 V2 Makes Conductive 3D Printing Practical for Desktop Machines

Copper is central to almost every fast-growing industry right now, and prices have been hitting record highs. That makes conductive 3D printing more than a novelty. It becomes a way to reduce waste, cut lead times, and produce custom electronics parts without waiting for traditional manufacturing.

Indiana-based Kupros, Inc. makes Cu29, an all-metal conductive filament designed for consumer desktop FFF and FDM machines. The company just launched the second generation of the product. The first batch of 90 kilograms sold out quickly.

The bigger news is what comes next. Kupros is developing a patent-pending workflow that goes beyond printing simple conductive traces. The goal is embedded electronics: conformal antennas, sensors, and full electronic circuits built directly into 3D printed parts during a standard FDM workflow.

Oak Ridge National Laboratory is already evaluating Cu29-enabled sensor test articles. If those tests succeed, the filament moves from hobbyist projects to validated military and industrial use cases.

Why desktop matters

Most conductive printing research happens on expensive industrial systems. Kupros is targeting the printer you might already own. That lowers the barrier to entry for engineers, students, and small manufacturers who want to experiment with printed electronics without buying a $100,000 machine.

The US Army DEVCOM Armaments Center recently demonstrated remote 3D printing for drone electronics repair during the Valiant Shield 2026 exercise. Marines on site asked for automated solutions that combine diagnostics with printed electronics components. Kupros and its sister company Sciperio are already involved in adjacent military work, which makes this a natural fit.

Education is another target market. Getting students interested in manufacturing is hard unless the work feels relevant. Electronics projects do that. A filament that lets a student print a working circuit at their desk could channel some of that energy into useful technical skills.

Cu29 V2 is available now in limited batches. The patent-pending embedded-electronics workflow is still in development, but the direction is clear: desktop 3D printers are on their way to becoming electronics manufacturing platforms.
