3D Print-On-Demand Electronics, Sensors, and Antennas

KUPROS revolutionizes the 3D printed antenna and electronic market with an all-metal copper filament that offers a more cost-effective, versatile, and efficient printing process than any other existing solution.

About Kupros

Disrupting 3D Printed Electronics and Antennas

Kupros is an early-stage startup. Our filament originated out of a DoD

national laboratory and is a Delaware C-Corp.

Sign Up For Our 3D Printing Competition

Embedded Electronic Circuit 3D Printing

KUPROS Inc is about to start full-scale production of the world's most conductive 3D printer filament! The Cu-29 filament prototype is 80x more conductive than filaments currently available today and can be used in consumer-grade 3D printers (you don’t need to spend $250k or more for a printer to create a conductive circuit!)

To demonstrate the huge impact this new conductive 3D printing technology will have on the Additive Manufacturing market, we’re calling on all 3D printing enthusiasts to submit entries for our “Embedded Electronic Circuit 3D Printing Competition”.

We will select 10 finalists from the submissions and print them at our facility using our MAKERGEAR M3-ID 3D printer. The final products will then be demonstrated, and videos posted on our website for 3D printing enthusiasts to vote for the winning submission.

The purpose of the competition is to demonstrate the level of sophistication of embedded 3D printed electronic circuits that can be created on consumer-grade 3D printers. The design should demonstrate functionality that can be observed and assessed via a video.

Our Products

Kupros is an "Innovation First" Company.

We are committed to rapid and ongoing research and development. See below for our planned product range.


Our Cu-29 filament is more than 80X more conductive, and significantly more cost-effective than its closest competitor. The resistivity is currently tested at 0.0000743 ohm/cm vs 0.006 ohm/cm. It is compatible with the most common Fused Filament Fabrication (FFF/FDM) 3D Printers.

High Conductive Variant

(Planned Release Date 2023 Q3)

The next generation of the Kupros family of conductive filaments Cu-29HC will be at least 20% more conductive than the base Cu-29 product, while still being printable using consumer quality FFF/FDM printers.

Aerospace Variant

(Planned Release Date 2023 Q2)

At high altitudes and in space applications, electronic circuits are subject to increased failure rates due the the higher intensity of electromagnetic radiation. The Kupros Aerospace Variant has been formulated to improve the reliability and longevity of printed embedded circuits. NASA has already expressed an interest in large-scale procurement of this variant.

Radiation Hardened Variant

(Planned Release Date 2023 Q3)

In certain military and industrial applications, using embedded electronic circuits in situations experiencing high levels of ionizing radiation is inevitable. The high levels of radiation degrade the performance of electronic circuits. The Radiation Hardened filament is designed to ameliorate this problem in embedded printed circuits.

Our Technology

Kupros, Inc’s all-metal copper filament Cu-29 is made without any polymer additives through an innovative, cost-effective process. The filament is used similarly to consumable ink for home-office printers and can print anything that requires conductive properties. The unique formula for Cu-29 eliminates the need for time and material-intensive post-processing, prevents separation from underlying material, and prints circuits unparalleled in conductivity when using the most common 3D printer available on the market.

3D printed circuits with similar conductivity currently require expensive, specific use case printers that inhibit an operator's ability to make rapid prototypes in an efficient, cost-effective manner. Future iterations of the formula will be specific to the aerospace and medical device industries for even further applications.
