An addition to additive manufacturing sews a number of printed substrate sheets together using industrial sewing machine technology. Portions of the final 3D object that will be solid are sewn together into bundles of the object with a needle protruding through the top of the bundle via a sewing machine with a looping mechanism connecting the thread loops under each bundle of printed substrate sheet layers. This will result in many well connected stack bundles that are then stacked in alignment to form the final stack. During heat and compression, the stitch thread may bunch together and become entangled with the cooled plastic of the final solid 3D object. Removal of the excess substrate may proceed as usual, since the sewing is applied only in the solid portions of the final object. The end result will be a part with much higher strength in the Z axis.

Disclosed is a nanowire bundle array. Particularly, the nanowire bundle array according to an embodiment of the present disclosure includes a plurality of nanowire assemblies arranged therein. Each of the nanowire assemblies includes nanowires, a surface of at least a portion of which is coated with a thin metal film and the widths between the nanowires gradually decrease from one end to another end.

A metal oxide macroscopic fiber and a preparation method thereof, the method including: adding, as a spinning dope, an anionic metal oxide aqueous colloidal solution into wet spinning equipment, extruding the spinning dope from the spinning equipment into a thread, injecting the extruded thread into a coagulating bath containing a flocculating agent to obtain as-spun fiber, and repeatedly washing the resulted as-spun fiber with deionized water and drying same, thereby obtaining a metal oxide fiber. Said method makes the process simple and controllable, being adaptable to production on a large scale. The prepared metal oxide fiber having special physical and chemical properties is widely applicable in terms of intelligent spinning, biomedicine, energy recycling and conversion, and the field of microelectronic devices and the like.

The object of the present invention is to provide the gelatinous, molten salt having a high ion-conductivity and an excellent heat resistance. The object of the present invention can be solved by the inorganic nanofibers having a functional group which inter-molecularly interacts with the molten salt on the surface thereof, and the molten salt composition comprising molten salt; or the method for increasing a viscosity of liquid molten salt characterized in that the inorganic nanofibers having a functional group which inter-molecularly interacts with the molten salt in the surface thereof is added to the liquid molten salt.

Disclosed is a thermoplastic polyurethane yarn and a fabric made from the thermoplastic polyurethane yarn that uses succinate as a polyol in a thermoplastic polyurethane composition comprises of isocyanate, glycol and polyol, and further includes nano-silica having a particle size of 100 nm or less added in the polymerization of the composition, thereby increasing the crystallization rate during the cooling and drawing processes to enable a continuous spinning of yarns without yarn breaking and also realizing a continuous spinning of low-hardness (Shore A type) thermoplastic polyurethane yarns with great stretch and recovery.
