Problems solved by technology

At present, 3D printing consumables are mainly engineering plastics, photosensitive resins, rubber materials, metal materials, ceramic materials, gypsum materials and other wire materials. Currently, ABS and PLA are generally two types of printing wire materials. For short fiber 3D Printing consumables are relatively mature, but the mechanical properties of all consumable molding components are still limited, which limits their industrial application range and cannot meet the needs of 3D printing technology market development
