Researchers find a way to heat 3D printer filament using microwaves, enabling fusing circuits inside printed objects — tech supports precise heating down to the width of a human hair

Researchers at Rice University have developed a new 3D printing process using microwaves, called Meta-NFS, that can heat nanoparticle ink with extreme precision. This technology allows for the fusing of circuits inside 3D printed objects, a capability previously unattainable with traditional manufacturing methods. Meta-NFS enables the use of a wider range of materials and improves production efficiency by adjusting microwave power in real-time. The applications of this technology include integrating electronics into soft materials like robots, implants, and plants, showcasing its potential for groundbreaking advancements in electronic manufacturing.
