  • PRECURSOR COMPOSITIONS INCLUDING A CURABLE COMPONENT AND SURFACE COATED OR MODIFIED HOLLOW GLASS MICROSPHERES, ARTICLES, ADDITIVE MANUFACTURING METHODS, AND METHODS OF INTERFERING WITH ELECTROMAGNETIC RADIATION
    Publication number: 20240150551
    Abstract: The present disclosure provides compositions, articles, and methods related to altering electromagnetic radiation. An actinic radiation curable precursor composition of a three-dimensional article includes a) a resin comprising an actinic radiation curable component, wherein the resin has a viscosity no greater than 500 cP; b) hollow glass microspheres having a density no greater than 2 g/mL and an average diameter no greater than 200 micrometers; and c) a photoinitiator. At least part of the surface of the hollow glass microspheres comprises a surface coating or modification. An article includes a photo(co)polymerization reaction product of the composition. A method of manufacturing a three-dimensional article includes the steps of a) providing an actinic radiation curable precursor composition; and b) selectively exposing a portion of the composition to a source of actinic radiation to at least partially cure the exposed portion of the composition, thereby forming a cured layer.

  • METHOD OF MAKING HOLLOW GLASS MICROSPHERES
    Publication number: 20180215644
    Abstract: Provided are methods of manufacturing hollow glass microspheres where a feed composition comprising a glass powder and a blowing agent entrained in the glass powder is introduced into an opening at a first end of a vertically-aligned furnace. Agglomerated glass, unmelted oxides, or natural glassy materials can be used in place of, or in addition to, the glass powder in the feed composition.
