Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

The present invention provides a method and device for forming a continuous fiber composite material by combining additive and subtractive manufacturing. According to the present invention, a resin filament and a continuous fiber are fed into a printing head and are melt and deposited, to first form a continuous fiber reinforced composite material by additive manufacturing by means of melt deposition forming; and after forming is completed, size and morphology data acquisition is performed to obtain the actual size of a part; a subtractive path is planned, and subtractive forming is carried out by a laser. According to the present invention, additive and subtractive forming is used for the continuous fiber composite material, additive forming is carried out by means of melt deposition, laser subtractive machining is performed, so that a device structure is simplified, machining stress and mechanical deformation are reduced, three-dimensional measurement and subtractive planning are carried out on the part, the automation degree is improved, and forming precision of the part made of the continuous fiber composite material is comprehensively improved.
