Copprint supplies nano‑copper ink formulations that enable additive, self‑sintering printing of conductive patterns on a wide range of substrates, including paper, PET, FR4, PI, glass, and photovoltaic cells. The inks deliver conductivity within 5 % of silver at 5–10× lower cost and up to 90 % material savings, while eliminating hazardous chemicals through rapid air‑based sintering and supporting multiple printing methods for sustainable, on‑shore production of PCBs, RFID antennas, and other printed electronics.

Problem
Traditional printed electronics rely on expensive silver inks or hazardous chemical etching processes, leading to high material costs, toxic waste, and limited substrate flexibility. This hampers sustainable, low‑cost manufacturing of conductive patterns for PCBs, RFID antennas, photovoltaics, and other devices.
Solution
Copprint provides nano‑copper ink formulations that enable additive, self‑sintering printing of conductive copper patterns on a wide range of substrates, including paper, PET, FR4, PI, glass, and photovoltaic cells. The inks achieve conductivity within 5 % of silver while costing 5–10 × less and delivering up to 90 % material savings versus etching. Rapid self‑sintering occurs in ambient air, eliminating the need for hazardous chemicals and allowing high‑throughput production on‑shore. The technology supports multiple printing methods—screen, flexo, gravure, inkjet, dispensing, and LIFT—giving designers full freedom to create complex, double‑sided traces and lightweight PCB designs. By using recycled copper and fully compostable substrates, Copprint’s process reduces carbon emissions by up to 40 % and eliminates toxic waste, offering a sustainable alternative for printed electronics across industries.
Target Audience
Primary customers are manufacturers of printed circuit boards, RFID tags, photovoltaic modules, and other printed electronic devices seeking low‑cost, high‑performance, and environmentally sustainable conductive inks.
