Abstract: A composition includes specific amounts of a block polycarbonate-polysiloxane, a core-shell impact modifier, and, optionally, a block polyestercarbonate. The core-shell impact modifier has a core that includes polydimethylsiloxane or poly(butyl acrylate) or both, and a shell includes a poly(methyl methacrylate). The block polyestercarbonate-polysiloxane and the block polyester-carbonate are present in a total amount of greater than 60 weight percent to 99 weight percent. And the block polyestercarbonate-poly-siloxane contributes 0.3 to 0.7 weight percent of dimethylsiloxane units to the composition. Also described are an article comprising the composition, and a method of additive manufacturing utilizing the composition.

Abstract: A method of forming a three dimensional object comprising: depositing a layer of thermoplastic polymeric material in a preset pattern on a platform (14) to form a deposited layer (50); directing an energy source (54), via an energy beam at an energy source target area (56) on the deposited layer (50) to increase the surface energy of the deposited layer at the energy source target area; contacting the energy source target area (56) with a subsequent layer (52) wherein the subsequent layer (52) is deposited along a path of the preset pattern; wherein directing an energy source (54) at the energy source target area (56) 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.
