摘要： 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. Steps a) and b) are repeated so as to form a three-dimensional article. A three-dimensional article is provided, obtained according to the method. Methods of interfering with electromagnetic radiation originating from an electromagnetic radiation producing device are provided, including integrating an article into the electronic device or placing an article in the vicinity of the electromagnetic radiation producing device.

摘要： The invention relates to a 3d-printed dental restoration precursor, a 3d-printed array comprising a 3d-printed dental restoration precursor, a kit of parts comprising at least two 3d-printed dental restoration precursors or 3d-printed dental restorations and a process of producing such a 3d-printed array, 3d-printed dental restoration precursor or 3d-printed dental restorations. The 3d-printed dental restoration precursor comprises at least one crown unit having an outer surface and an inner surface and at least one support element having a fixation section. The support element is connected through the fixation section to the outer surface of the crown unit in a particular region.
