A method for manufacturing carbon fiber blended modified 3D printing consumables, comprising steps:
- step 1:
- preparing raw materials comprising a plastic required for manufacturing the carbon fiber blended modified 3D printing consumables and proportioning the raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables according to a predetermined ratio of the raw materials;
- step 2:
- putting proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables into a high-speed mixer;
- mixing the proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables at a high speed for ten to twenty minutes, by the high-speed mixer, to evenly mix the proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables;
- and obtaining a mixture of the proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables;
- step 3:
- putting the mixture of the proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables into a twin-screw modified granulator;
- putting a predetermined proportion of carbon fiber material into the twin-screw modified granulator through a side feeding mechanism;
- and processing the carbon fiber material with the mixture of the proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables;
- step 4:
- modifying the mixture of the proportioned raw materials required for manufacturing the carbon fiber blended modified 3D printing consumables and the carbon fiber material by the twin-screw modified granulator;
- and coupling and extruding modified materials by the twin-screw modified granulator to obtain a plastic wire blended with plastic and carbon fiber;
- step 5:
- putting the plastic wire blended with plastic and carbon fiber into a water tank to cool;
- after cooling, cutting the plastic wire into pellets through a pelletizing device;
- and drying the pellets through a dryer after pelletizing;
- step 6:
- putting dried pellets into a single-screw wire-drawing device;
- and processing the dried pellets to obtain manufactured 3D printing consumables;
- and
- step 7:
- cooling the manufactured 3D printing consumables through a cooling water tank, and rewinding the manufactured 3D printing consumables by a tractor and a winding device connected with the tractor;
- wherein the carbon fiber blended modified 3D printing consumables in the step 1 is selected from a group consisting of carbon fiber polycarbonate 3D printing consumables, carbon fiber polylactic acid 3D printing consumables, carbon fiber copolyester 3D printing consumables, carbon fiber copolymer 3D printing consumables, carbon fiber nylon 3D printing consumables, and other carbon fiber plastic 3D printing consumables;
- wherein when manufacturing the carbon fiber polycarbonate 3D printing consumables, the raw materials to be proportioned according to the predetermined ratio comprise polycarbonate in a range of 20-60% by weight, copolyester in a range of 20-60% by weight, phase solvent in a range of 1-5% by weight, antioxidant in a range of 0.3-1% by weight, and carbon fiber material in a range of 3-5% by weight for manufacturing the carbon fiber polycarbonate 3D printing consumables;
- wherein when manufacturing the carbon fiber polylactic acid 3D printing consumables, the raw materials to be proportioned according to the predetermined ratio comprise polylactic acid in a range of 40-80% by weight, toughening agent in a range of 5-15% by weight, the phase solvent in a range of 1-5% by weight, the antioxidant in a range of 0.3-1% by weight, and the carbon fiber material in the range of 3-5% by weight for manufacturing the carbon fiber polylactic acid 3D printing consumables;
- and
- wherein when manufacturing the carbon fiber copolyester 3D printing consumables, the raw materials to be proportioned according to the predetermined ratio comprise the copolyester in a range of 40-80% by weight, the toughening agent in the range of 5-15% by weight, the phase solvent in the range of 1-5% by weight, the antioxidant in the range of 0.3-1% by weight, and the carbon fiber material in the range of 3-5% by weight for manufacturing the carbon fiber copolyester 3D printing consumables.
