1. A shaping machine comprising:
a melting vessel having an irradiation region permeable to an electromagnetic field, the irradiation region being formed of an opening in the melting vessel;
an induction coil arranged on the melting vessel for inductively heating a material;
a shaping cavity; and
a body having a higher magnetic permeability than the melting vessel, the body being arranged to overlap the opening forming the irradiation region of the melting vessel without surrounding the melting vessel, and the induction coil being arranged between the body and the irradiation region;
wherein the shaping cavity is configured to allow the material in the shaping cavity to cool such that a crystalline solid body is formed, and
wherein the induction coil is arranged between the body and the irradiation region, and the body is configured to concentrate electromagnetic flux generated by the induction coil onto the irradiation region.
