The invention discloses a polypropylene 3D printing wire with high strength and toughness and a preparation method thereof. Components such as thermoplastic elastomer TPU-coated glass fiber, compatibilizer, tackifying resin and antioxidant are introduced into a polypropylene matrix, mixed and extruded via a twin-screw extruder, and then extruded into a filamentous printing wire via a single-screw extruder. The component raw materials of the invention are easily available, the preparation process is simple, efficient and low-cost, and the prepared polypropylene wire has high strength and toughness, can be widely and stably applied in the field of 3D printing, and has broad application prospects in high-strength and high-toughness structural parts.
