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.
