Device and method for processing a 3D polymer structure

A device configured for processing a 3D polymer structure with a paramagnetic substance distributed as homogeneously as possible in a material or a polymer precursor of the 3D polymer structure, comprising:

• a magnetic field generator configured for generating a static magnetic field B0 in a working zone of the device, in which the 3D polymer structure can be arranged;
• gradient coils configured for generating magnetic gradient fields B1, B2, B3 in at least all three spatial directions x, y, z, by means of which the paramagnetic substance can be spatially encoded in a defined voxel V of the 3D polymer structure;
• a radio frequency field generator for irradiating RF radiation into the working zone;
• and
• a control unit which is configured to control the RF field generator in such a way that the spatially encoded paramagnetic substance in the voxel V can be excited by means of a field frequency f of the RF radiation tuned to the paramagnetic substance in order to destroy the 3D polymer structure solely in the defined voxel V;
• wherein the device comprises an MRI unit or a different imaging appliance for obtaining image data;
• and
• wherein the control unit is configured to compare the image data of the 3D polymer structure with CAD/CAM data for the 3D polymer structure and, if deviations of the partially processed/partially generated 3D polymer structure from the CAD/CAM data are detected, being geometric deviations, to take into account the image data and/or the deviations during the further processing/generation of the 3D polymer structure.
