摘要： Methods of making articles using additive manufacturing processes are disclosed. The article is built up from a multitude of layers. At least one layer includes a modeling material comprising a cross-linkable polycarbonate resin containing a photoactive group derived from a benzophenone. When exposed to an effective dosage of ultraviolet radiation, the modeling material crosslinks. This improves various properties of the final article.
