Is this the Worlds First fully 3D printed Peltier Thermal Electric Generator/ Peltier Heating/Cooling Chip? I have been trying different metal filled 3D printing materials to find which ones may work for 3D printing Peltier Chips, so far I have had only one companies metal composite filaments produce any usable results. So far the higher the metal content the better the result have been, I have had even better results with oxidized materials!
