The present invention provides a resin composition having high heat-resisting properties, with which a shaping can be performed in accordance with designed sizes using a fused deposition modeling method-3D printer, and from which a shaped object having a small warpage and small changes in sizes due to water can be obtained. The present invention relates to a resin composition for a shaping material of a fused deposition modeling method-3D printer, comprising cellulose fibers in a polyamide.

Resin composition for shaping material of fused deposition modeling method-3D printer and filamentary molded body thereof

Disclosed is a semiaromatic polyamide resin composition including a semiaromatic polyamide (A), a phosphorus-based flame retardant (B) and an inorganic aluminum compound (C), wherein the mass ratio (A/B) between (A) and (B) is 50/50 to 95/5; the amount of the inorganic aluminum compound (C) is 0.1 to 20 parts by mass in relation to 100 parts by mass of the total amount of (A) and (B); (A) is constituted with an aromatic dicarboxylic acid component, an aliphatic diamine component and a monocarboxylic acid component; and the content of the monocarboxylic acid component is 0.3 to 4.0 mol % in relation to the whole monomer components constituting (A).

Semiaromatic polyamide resin composition and molded body formed by molding same

A resin composition is provided, which comprises: 40 to 95% by mass of a resin component containing 10 to 100% by mass of a polyarylate resin and 90 to 0% by mass of a polycarbonate resin; and 60 to 5% by mass of spherical silica having an average particle diameter of not greater than 10 &#x3bc;m. The resin composition is molded into a product.

Resin composition and product molded from the same

Provided is a polylactic acid resin composition obtained by adding a carboxylic acid amide and a carboxylic acid ester each of which has at least one polar group in a molecule to a polylactic acid resin reacted with a (meth)acrylate compound. Also provided is a polylactic acid resin molded article which is a molded article obtained by molding the polylactic acid resin composition, manufactured by setting a mold temperature to a glass transition temperature of a polylactic acid resin plus 20&#xb0; C. or higher and a melting point thereof minus 20&#xb0; C. or lower, at the time of injection molding the polylactic acid resin composition. Thus, a resin composition in which a moldability is improved at a temperature at which a polylactic acid resin is crystallized, and a molded article therefrom are provided.
