This use case shows the weldability of components from additive manufacturing with green laser light. In this case TRUMPF offers "everything from a single source", since the green laser beam source can be connected to the TruPrint machine.  In addition to the welded joint, the example part shows that any surface can be printed using a green laser with minimal heat input and maximum reproducibility can be achieved.  With the levitation coil, a metallic body can be levitated and melted in an electromagnetic field. The seamless 3D printing of the component reduces joining and solder joints to prevent leaks in the inner cooling channel. Complex geometry requirements for wall thickness and shape are implemented.
