FILAMENT RESIN MOLDED ARTICLE
Provided is a filament resin molded article capable of reliably maintaining a shape of a 3D model when a shape memory resin is three-dimensionally formed. With the filament resin molded article, it is possible to form 3D models of various shapes, and to improve a curing speed. The filament resin molded article contains a shape memory resin and an inorganic filler. The inorganic filler is, for example, a glass fiber or a carbon fiber. The filament resin molded article is used for a hot melt lamination type 3D printer. A deformed shape is fixed by deforming a 3D shaped object formed using the filament resin molded article containing the shape memory resin, at a temperature which is equal to or higher than a glass transition temperature (Tg) of the shape memory resin and lower than a melting temperature or a decomposition temperature, and cooling the 3D shaped object to the glass transition temperature or lower while maintaining its shape. An original molded shape is recovered by heating the 3D-shaped object in the temperature which is equal to or higher than a glass transition temperature, and lower than a melting temperature or a decomposition temperature.

POLYMERS FOR ADDITIVE MANUFACTURING
Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away front the printed part, resulting in a part having surface cavities.

Method for producing shaping material
Provided is a method for producing a shaping material that contains a cyclic olefin polymer and has a low content of a volatile impurity. This method for producing a shaping material is a method which includes passing a raw-material resin in a molten state through an extruder to produce a shaping material, and in which the extruder is equipped with a cylinder, a screw housed within the cylinder, a resin introduction port for introducing the raw-material resin into the cylinder, a resin discharge port for discharging the molten resin from the cylinder, a fluid injection port for injecting carbon dioxide or water into the cylinder between the resin introduction port and the resin discharge port, and a fluid discharge port for removing fluid in the cylinder by suction downstream of the fluid injection port and between the resin introduction port and the resin discharge port.

COOLER BOX MANUFACTURING METHOD
A cooler box manufacturing method includes the steps of bonding an acrylonitrile butadiene styrene (ABS) sheet material to a polycarbonate (PC) layer to form a two-layered panel; heating and softening the two-layered panel and attaching the latter to a forming mold by vacuum suction to provide a rigid body shell and a rigid cover shell; sequentially attaching insulation pads and inner wall layers to inner surfaces of the rigid body and cover shells to provide a cooler box body and a cooler box cover that respectively internally have insulation pad or pads covered by an inner wall layer; and finally, pivotally connecting the cooler box cover to the cooler box body to complete a cooler box. The cooler box so manufactured has rigid shells to not only provide heat and cool insulation for food and beverage storage, but also prevent the stored food and beverage from colliding with one another.
