3D printing or additive manufacturing technology has gained increasing attention owing to its advantage of designing freedom. However, a significant disadvantage arises in the poor surface quality of 3D printed surfaces, which has become one of the critical factors limiting the development of 3D printing technology. This paper innovatively demonstrates the post process finishing of the 3D printed components using the fluid jet array finishing (FJAF) method, in which an array of the pressurized abrasive fluid jets impinge the target surface to implement the material removal. It possesses much higher material removal rate as compared to traditional single jet method and still has high flexibility to the freeform surfaces. Experimental and analytical study were conducted to investigate its feasibility for the polishing 3D printed surface. The experimental results show that the FJAF method is effective for the post process finishing of the 3D printed components.
