Using 3D printing to create 3D circuits: Researchers unlock self-healing boards | A Singapore team has developed a novel 3D printing technique for three-dimensional circuits
By going vertical instead of staying flat, components can be stacked up, meaning much smaller footprints for our electronics – and we all want our devices smaller...
The unique combination of properties helps CHARM3D print super smooth, uniform 3D metal microstructures from 100-300 microns wide – about as thin as a few human hairs. As the researchers mention, the high resolution, speedy printing (up to 100 millimeters per second), and the ability to create complex 3D shapes make it viable for all sorts of cool stuff. The team has already used the tech to make a wearable battery-free temperature sensor, antennas for wireless vital sign monitoring, and metamaterials for manipulating electromagnetic waves.
