    Abstract: A method for forming a component includes providing a first layer of a mixture of first and second powders. The method includes determining the frequency of an alternating magnetic field to induce eddy currents sufficient to bulk heat only one of the first and second powders. The alternating magnetic field is applied at the determined frequency to a portion of the first layer of the mixture using a flux concentrator. Exposure to the magnetic field changes the phase of at least a portion of the first powder to liquid. The liquid portion couples to at least some of the second powder and subsequently solidifies to provide a composite component.

The workpiece is inductively heated quickly with no need for pushing onto a magnet yoke, because of its horizontal bearing. The planar configuration of the solenoid coil, following the contact surface shape, causes the driver resonant circuit to be operated at high frequency, resulting in low power consumption. The profile of the lines of force causes the magnetic field to directly enter areas to be heated on an upper workpiece surface, ensuring homogeneous workpiece heating.
