UC Berkeley: UC Berkeley researchers develop charge-programmed 3D printing platform for lightweight antennas

Researchers at the University of California, Berkeley, have developed a novel 3D printing technique capable of fabricating ultra-light, structurally complex antennas using a charge-guided multi-material deposition process. The method, called Charge Programmed Deposition (CPD), enables the direct 3D printing of electromagnetic devices with intricate metal-dielectric architectures, eliminating the need for traditional lithographic or subtractive manufacturing [...]
