Additive Manufacturing (AM) is a process that builds 3D objects by depositing material layer by layer. It provides exceptional geometric flexibility, which is often difficult to achieve through traditional manufacturing methods. The aerospace industry was among the earliest adopters of AM, which has gradually been applied to the rapid production of precision components such as rocket combustion chambers, engine nozzles, turbine parts, and aircraft rudder.

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.
