Abstract
The present invention relates to a 3D printer polymer filament improving strength of a polymer resin and providing durability by using graphene coated metal nanoparticles and carbon nanotubes, and expressing a function of the graphene coated metal nanoparticles and the carbon nanotubes as a filler, and a manufacturing method thereof. Accordingly, according to the present invention, the 3D printer polymer filament and the manufacturing method includes mixing the graphene coated metal nanoparticles, the carbon nanotubes, and the polymer, using the manufactured mixture to form a filament through extrusion, and forming a 3D printed article by using the filament, thereby improving the strength and the durability by using the graphene coated metal nanoparticles and the carbon nanotubes.
