  • Publication number: 20190389140
    Abstract: A method manufacturing a three-dimensional article having readable indicia includes three-dimensionally printing the article and post-processing that following the printing. The three-dimensional printing forms the three-dimensional article in a layer-by-layer manner. The resultant three-dimensional article includes an outer portion of build material defining a plurality of enclosed internal channels, an encapsulated support material containing a phosphor component defining the indicia disposed within the channels, and unencapsulated support material that provides structural support to otherwise unsupported portions of the build material during the three-dimensional printing. The post-processing removes the unencapsulated support material form the build material but leaves the encapsulated build material.

  • Publication number: 20190389123
    Abstract: A method of manufacturing a three dimensional article includes forming the three-dimensional article with three-dimensional printing, processing the three-dimensional article to remove support material ink, illuminating the three-dimensional article with electromagnetic radiation, inspecting the three dimensional article for photoluminescence that is responsive to the illumination, and verifying whether the support material has been sufficiently removed based upon the inspection. The support material ink includes a phosphor component that phosphorescently emits light in response to the illumination.
