A polyamide resin composition for an extrusion-molded article exposed to high-pressure hydrogen gas contains: 70 to 99 parts by weight of a polyamide 6 resin (A); 1 to 30 parts by weight of an impact modifier (B); and 0.005 to 1 parts by weight of a metal halide (C) with respect to a total of 100 parts by weight of the polyamide 6 resin (A) and the impact modifier (B). The polyamide resin composition has a melt tension of 20 mN or more when measured at 260° C. and a take-up speed at strand break of 30 m/min or more when measured at 260° C.

There is a lead casing for pencil for writing, drawing, marking, plotting, and/or coloring. The casing is made of a composition having, by weight relative to the total weight of the lead casing for pencil: a) from 50 to 95% of a mixture of polylactic acid and bio-polyethylene in a weight ratio polylactic acid/bio-polyethylene ranging from 60/40 to 90/10, and b) from 5 to 40% of mineral fillers chosen in the group consisting of shellfish shells, more specifically oyster shells, and even more specifically milled oyster shells. There is also a pencil including the lead casing of the disclosure for writing, drawing, marking, plotting, and/or coloring, as well as a method for manufacturing such a pencil.

An apparatus, a system, and a method for improvements in fused filament fabrication (FFF). Characteristics of a filament may be measured during production of the filament and the characteristics stored in a memory for retrieval by a 3D printer. The 3D printer adjusts print settings as necessary based on the measured characteristics, thereby resulting in better print quality.
