The invention discloses a 3D printing modification machine capable of laying a carbon fiber/resin composite material product at an angle. The 3D printing modification machine comprises a machining platform, a fiber penetrating plate structure, a fiber resin multifunctional spray head and a modification cutter, the diameter of a single-layer fiber penetrating plate can be independently selected according to the size of a workpiece during printing, the number of layers of the fiber penetrating plate structure can be determined by the size of the machined workpiece, carbon fibers can be effectively saved by selecting the proper number of layers of the fiber penetrating plate structure, and meanwhile the fiber penetrating efficiency is improved; the fiber resin multifunctional spray head comprises a fiber laying spray head, a thermoplastic material spray head, a spray head converter and a heating spray head, and can achieve the functions of fiber laying, resin spraying, solidification accelerating and intelligent
