Device and method for the additive manufacture of a workpiece

A device for additive manufacturing of a workpiece (10;

• 30), comprising:
• a cell building space (24) for the workpiece to be built,
• additive manufacturing means (14;
• 34, 36) provided on or in the building space,
• workpiece measurement means (16, 18, 20;
• 40, 42;
• 82, 86) on or in the building space in such a manner that the workpiece measurement means provides the developing or completed workpiece with irradiation from an irradiation source (16;
• 40) and/or a nuclear spin magnetic field excitation, and
• detector means (22;
• 42) configured to detect an irradiation image of the workpiece provided with the irradiation on and through an outer wall of the workpiece and/or to detect a nuclear spin image of the workpiece provided with the magnetic field excitation and to generate workpiece measurement data from the irradiation image or the nuclear spin image, whereas the irradiation source (16;
• 40) is configured to provide irradiation along a beam path (20) through the workpiece to the detector means (22;
• 42), which is disposed along the beam path (20) at an opposite side of the workpiece from the irradiation source (16;
• 40).
