The European Space Agency (ESA) has long been a fan of 3D printing; now, as the first test of its new 3D printable electrically conductive hard plastic, the ESA has 3D printed CubeSats, with their own electrical lines. The ESA has been working recently with robust PEEK thermoplastic 3D printing material, which is stable, strong, and temperature resistant, with a melting point of around 370°C. To demonstrate its breakthrough with the electrically conductive PEEK material, the ESA team chose to 3D print CubeSat bodies.
