Disclosed is an ABS-based resin composition, a method of preparing the same, and a molded article including the same, including an ABS-based resin composition including 100 parts by weight of a base resin including 20 to 40% by weight of a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer and 60 to 80% by weight of an aromatic vinyl compound-vinyl cyanide compound copolymer; and 0.1 to 5 parts by weight of a polyether-modified polysiloxane, a method of preparing the ABS-based resin composition, and a molded article including the ABS-based resin composition.

An additive manufacturing system is provided. The additive manufacturing system includes a build platform and at least one workstation. The build platform defines a continuous workflow path and is configured to rotate about a build platform axis. The workstation is spaced apart from the build platform along the third direction and at least one of the build platform and the workstation is configured to move along the third direction. The workstation includes at least one particle delivery device, at least one recoating device, and at least one consolidation device. The particle delivery device is configured to deposit particles on the build platform. The recoating device is configured to distribute the deposited particles to form a build layer on the build platform. The consolidation device is configured to consolidate at least a portion of the build layer.

The invention generally relates to a method of making a plastic aggregate, and its use to make concrete products. The aggregate is formed by providing a granulated waste plastic material, introducing the granulated waste plastic material into an extruder having a die, the die having a ratio of die nozzle open area to die land area of about 1:10 to about 1:40, and extruding the granulated waste plastic material through the extruder to generate an extruded plastic aggregate. The method can include the presence of controlled cooling, the addition of additives and treatment of the surface of the aggregate to produce a desired aggregate that can be used to make a concrete product with desired properties, such as compressive strength and weight.

A foam bead intended in particular for the production of molded parts is also intended to be particularly suitable for novel, hitherto unknown applications, especially after processing into a corresponding molded part. For this purpose, the foam bead comprises, according to the invention, a core formed by a first plastic and a shell formed by a second plastic and at least partially surrounding the core, the second plastic forming the shell having a lower melting point than the first plastic forming the core.
