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.

摘要： A reduced density article of manufacture, and process for making same, made from a thermoplastic polycarbonate composition. The reduced density article of manufacture has (1) a certain density and (2) a certain micro structure containing from 1% to 20% by volume of voids wherein at least 80% of the voids are high aspect voids and less than 20% of the voids are spherical voids with a diameter of 10 to 100 microns. The polycarbonate thermoplastic composition comprises at least 50 mole % of a certain bisphenol A. The reduced density article of manufacture is made by a monofilament additive manufacturing technique.
