摘要： A polyetherimide composition includes specific amounts of a polyetherimide, a block polyestercarbonate, a block poly-carbonate-polysiloxane, and a core-shell impact modifier in which the core includes a polysiloxane and the shell includes a poly(alkyl (meth)acrylate). Relative to a corresponding composition lacking the core-shell impact modifier, the polyetherimide composition exhibits increased impact strength while substantially retaining flame retardancy. Also described are associated articles, including articles formed by additive manufacturing, and a method of additive manufacturing.

摘要： A core-shell filament useful for fused filament fabrication includes a core, and a shell surrounding and in contact with the core. The core contains a block polyetherimide-polysiloxane. The shell contains a polyetherimide. When the filament is used in fused filament fabrication for printing a three-dimensional article, the core material remains surrounded by shell material. So, the printed article exhibits good interlayer adhesion provided by the shell material, and good ductility provided by the core material.

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 method of forming a three dimensional object comprising: depositing a layer of thermoplastic polymeric material in a preset pattern on a platform to form a deposited layer; directing an energy source, via an energy beam at an energy source target area on the deposited layer to increase the surface energy of the deposited layer at the energy source target area; contacting the energy source target area with a subsequent layer wherein the subsequent layer is deposited along a path of the preset pattern; wherein directing an energy source at the energy source target area comprises applying energy to the layer at an area preceding the depositing of the subsequent layer to that area; and repeating the preceding steps to form the three dimensional object.
