Resin matrix composite lightweight structure has the advantages of low density and high performance

for use in lightweight applications such as aerospace

high-speed trains

ships and others. However

the disadvantages of conventional forming processes

such as complex process

long process period and high cost

have limited the wide applications of resin matrix composite lightweight structure. 3D printing is a new forming process of parts

and it is possible to realize integrated manufacturing of high performance composite lightweight structure. This paper reviews the research status of resin matrix composite lightweight structure 3D printing

and meanwhile presents a new integrated manufacturing process of high performance resin matrix composite lightweight structure based on continuous fiber reinforced thermoplastic composites 3D printing.
