Additive manufacturing allows for the direct conversion of design construction files into fully functional objects. With 3D-printing objects, from metals, plastics, ceramics, glass, sand or other materials are built-up in layers until they have reached their final shape.
Depending on the material, the layers are interconnected by means of a binder system or by laser technology.
Many methods of additive manufacturing require subsequent heat treatment of the manufactured components. The requirements for the furnaces for heat treatment depend on the component material, the working temperature, the atmosphere in the furnace and, of course, the additive production process.
