Abstract：Materials extrusion as a classical additive manufacturing process can melt, extrude and fabricate the thermoplastic components or their composites layer by layer. It has the advantages of no-molding, ability to form complex structure and low cost, thus to be used in medical, aerospace, and automobile fields. Poly (ether ether ketone), as a kind of semi-crystalline thermoplastic polymer, has many excellent characteristics such as light weight, high strength, good thermal stability, and corrosion resistance. It’s components can be fabricated by materials extrusion technology in low cost. In this paper, the development status of the materials extrusion of fiber reinforced poly (ether ether ketone) composites were introduced. The mechanism of the process, development process of the technology and detailed performance comparison were respectively discussed. In the end, the challenges of the fiber reinforced poly (ether ether ketone) composites extrusion for further development were analyzed.
