Copper exhibits exceptional thermal and electrical conductivity, enabling its extensive application in sectors such as aerospace, new energy vehicles, and high performance computing. Despite its industrial significance, copper remains challenging to process efficiently and with high quality via additive manufacturing techniques. One critical consideration is the laser wavelength utilized during the printing process.

High-frequency induction heating coils are devices that work using the principle of electromagnetic induction. A coil made of copper is placed near the workpiece to be heated, and a high-frequency current passes through the coil, generating a magnetic field. By using this induced current, the workpiece heats up by itself. These are important electronic components in industrial applications and are widely used in fields such as household appliances, automotive, power, telecommunications, consumer electronics, and rail transportation.
