The invention discloses a plastic recycling device for 3D printing, belonging to the field of 3D printing, which solves the problem of single processing mode of recycled plastic wires in the prior art. The technical solution to solve the problem mainly comprises a main frame, and a shredding assembly and a melt extrusion assembly on the main frame. The shredding assembly is used to crush plastics and convey them to the melt extrusion assembly, which melts and extrudes the crushed plastics into plastic wires. A wire winding assembly and a cooling traction assembly are also arranged on the main frame. The wire winding assembly is used to wind up plastic wires, and the cooling traction assembly is used to convey plastic wires to a 3D printer for printing. A connecting base is arranged on the main frame, and either the wire winding assembly or the cooling traction assembly is detachably connected to the connecting base. The invention is mainly used to provide multiple processing modes for recycling plastics for 3D printing.
