A continuous long fiber reinforced composites 3d printer and a printing method

A continuous long-fiber-reinforced composite material 3D printer and a printing method using 3D printing technology, in conjunction with the composite fiber placement technology, a continuous long-fiber reinforced resin matrix composite material 3D printing, the process and without prior custom mold pre-treated fiber prepreg tape, greatly reducing the cost; meanwhile, the 3D printing method, better and more easily control the direction of reinforcing fibers of the part produced, easier to obtain a composite part having a customized mechanical properties for fast manufacturing a composite part having a complicated structure; relative to the original composite fiber placement process, the present invention is a wider range of applications, higher productivity.
