Fiber　reinforced　polymer　composites　have　excellent　properties　of　light　weight　and　high　performance.　However,　most　of　conventional　manufacturing　processes　have　the　disadvantages　of　high　cost,　complex　process　and　difficult　recycling,　having　limited　wide　applications　of　composites.　A　novel　3D　printed　continuous　fiber　reinforced　thermoplastic　composites　(CFRTPCs)　is　presented　as　well　as　its　recycling　and　remanufacturing　strategy.　The　interconnections　between　the　forming　process　and　interface　performance　and　mechanical　properties　of　parts　are　studied.　The　flexural　strength　and　modulus　of　carbon　fiber　reinforced　PLA　composite　(CF/PLA)　are　about　390　MPa　and　30.8　GPa　respectively,　and　the　process　is　low　lost,　simple　and　rapid.　The　recycling　and　remanufactuing　strategy　is　proposed　without　any　pollution　generation,　with　a　high　material　recovery　rate　of　75%,　and　with　reprinted　specimens　25%　improvement　of　flexural　strength　than　original,　which　is　efficient,　non-downgrade　and　green.　An　end　of　life　composite　application　method　will　be　set　up　by　combining　CFRTPCs　process　with　its　recycling　and　remanufacuring　process.　©　2019　Journal　of　Mechanical　Engineering.
