1. A method of creating a 3D thermoplastic composite pultrusion with a 3D thermoplastic pultrusion system including a pultrusion die, and one or more sets of 3D thermoplastic forming machines including one or more pairs of shapeable and flexible dual-temperature bands, each pair of dual-temperature
1. A method of creating a 3D thermoplastic composite pultrusion with a 3D thermoplastic pultrusion system including a pultrusion die, and one or more sets of 3D thermoplastic forming machines including one or more pairs of shapeable and flexible dual-temperature bands, each pair of dual-temperature bands being capable of applying pressure at a specific thickness to a fiber thermoplastic composite material pultrusion from opposite sides, comprising the following for a given cross-section of the fiber thermoplastic composite material: consolidating and heating the fiber thermoplastic composite material by compressing and heating the fiber thermoplastic composite material with the thermoplastic pultrusion die system,simultaneous forming, heating, and chilling the pultruded heated fiber thermoplastic composite material into a 3D thermoplastic composite pultrusion having varying surface contours in both a pultrusion direction and 90 degrees to the pultrusion direction by simultaneously heating and chilling the pultruded heated fiber thermoplastic composite material and applying pressure with the one or more pairs of shapeable and flexible dual-temperature bands, programmed to be displaced in a manner such that the composite is heated, preformed, and chilled at a specific thickness assuring heating, preforming, and chilling at sufficient pressure,wherein the 3D thermoplastic pultrusion system includes a pultrusion gripper mechanism capable of CNC movement and gripping the heated and chilled thermoplastic composite having various changing shapes in the pultrusion direction, and the method further comprising gripping the heated and chilled thermoplastic composite having various changing shapes in the pultrusion direction with the pultrusion gripper mechanism to incrementally advance the fiber thermoplastic composite material and the heated, preformed, and chilled thermoplastic composite. 2. The method of creating a 3D thermoplastic composite pultrusion of claim 1, wherein the one or more pairs of shapeable and flexible dual-temperature bands each include a high-temperature region at an entrance, forward edge of the bands and a low-temperature region at an exit, rear edge of the bands, and simultaneous forming, heating, and chilling includes heating and preforming the pultruded heated fiber thermoplastic composite material with the high-temperature region at the entrance, forward edge of the bands and chilling the pultruded heated fiber thermoplastic composite material with the low-temperature region at the exit, rear edge of the bands. 3. The method of creating a 3D thermoplastic composite pultrusion of claim 2, wherein the heating by the high-temperature region prevents the pultruded heated fiber thermoplastic composite material from cooling as the pultruded heated fiber thermoplastic composite material moves through the high temperature region. 4. The method of creating a 3D thermoplastic composite pultrusion of claim 2, wherein the one or more pairs of shapeable and flexible dual-temperature bands are solid throughout. 5. The method of creating a 3D thermoplastic composite pultrusion of claim 2, wherein the one or more pairs of shapeable and flexible dual-temperature bands include a thermal break between the forward edge and the exit, rear edge of the bands, creating a thermal barrier between the high-temperature region and the low-temperature region. 6. The method of creating a 3D thermoplastic composite pultrusion of claim 2, wherein the one or more pairs of shapeable and flexible dual-temperature bands include a physical separation between the high-temperature region and the low-temperature region. 7. The method of creating a 3D thermoplastic composite pultrusion of claim 1, further including rotating the one or more sets of 3D thermoplastic forming machines with a rotating assembly to impart a twist to the heated and chilled thermoplastic composite. 8. The method of creating a 3D thermoplastic composite pultrusion of claim 1, further including a rotating assembly that carries and rotates the one or more sets of 3D thermoplastic forming machines about a rotational axis around an axis of pultrusion. 9. A method of creating a 3D thermoplastic composite pultrusion with a 3D thermoplastic pultrusion system including a pultrusion die, and one or more sets of 3D thermoplastic forming machines including one or more pairs of shapeable and flexible bands, each pair of bands being capable of applying pressure at a specific thickness to a fiber thermoplastic composite material pultrusion from opposite sides, comprising the following for a given cross-section of the fiber thermoplastic composite material: consolidating and heating the fiber thermoplastic composite material by compressing and heating the fiber thermoplastic composite material with the thermoplastic pultrusion die system,forming the pultruded heated fiber thermoplastic composite material into a 3D thermoplastic composite pultrusion having varying surface contours in both a pultrusion direction and 90 degrees to the pultrusion direction by applying pressure with the one or more pairs of shapeable and flexible bands,rotating the one or more sets of 3D thermoplastic forming machines with a rotating assembly to impart a twist to the heated and chilled thermoplastic composite,wherein the 3D thermoplastic pultrusion system includes a pultrusion gripper mechanism capable of CNC movement and gripping the formed thermoplastic composite having various changing shapes in the pultrusion direction, and the method further comprising gripping the heated and chilled thermoplastic composite having various changing shapes in the pultrusion direction with the pultrusion gripper mechanism to incrementally advance the fiber thermoplastic composite material and the formed thermoplastic composite. 10. The method of creating a 3D thermoplastic composite pultrusion of claim 9, further including a rotating assembly that carries and rotates the one or more sets of 3D thermoplastic forming machines about a rotational axis in the pultrusion direction.
