The present invention discloses a low-density polypropylene wire for 3D printing. By introducing components such as silicone resin-coated hollow glass microspheres, light-curable resin powder, photoinitiator, toughening agent, inorganic filler, tackifying resin and antioxidant into a polypropylene matrix, the components are mixed and extruded by a twin-screw extruder, and then extruded into a filamentous printing wire by a single-screw extruder. The component raw materials of the present invention are easily available, the preparation process is simple, efficient and low-cost. The prepared polypropylene wire has excellent properties such as low density, high toughness and low-temperature performance, can be widely and stably applied in the field of 3D printing, and has strong practicability and wide applicability.
