Value Proposition: We have developed a simple, low cost process for the manufacturing of 3D printed highly conductive polymer-based composites at room temperature. 3D printing of conductive materials has been always a challenge since the most frequently used conductive materials are metals. To overcome this issue, the addition of nanoparticles to a host polymeric material very often leads to significant improvements in material properties (e.g., mechanical, electrical, thermal) at relatively small loadings-size. However, increasing the concentration of nanoparticles to reach interesting conductivity properties is challenging due to mixing difficulties. In addition, the manufacturing of highly conductive ink from polymer-based composite inks is highly demanding and hardly accessible due to extrusion mixing difficulties of highly doped nanocomposite inks from fine nozzles.
Our technology has overcome those challenges and allows for highly conductive ink that can be easily extruded through the finest nozzles. The process is cost effective, easy to implement and can be done at room temperature. Thanks to its versatility, our ink can be adapted to large industrial manufacturing companies and also individual 3D printing users.
