Abstract
A process for the production of moldings via a layer-by-layer process by selectively melting regions of one or more powder layers that contain cyclic oligomers and have a median grain diameter determined by laser diffraction of between 25 and 150 μm via input of electromagnetic energy, and permitting the layers to solidify to provide a solid mass, where selectivity is achieved by applying one or more aids amongst the group of susceptors, inhibitors, absorbers, masks, and focusing of a laser beam.
