The invention belongs to the field of additive manufacturing, and discloses a detection method for a selective laser melting forming component. The method comprises the following steps that S1, ultrasonic cleaning and vacuum drying are conducted on the selective laser melting forming component; s2, an ultrasonic detection method is adopted for detecting the part, with the thickness smaller than 7.5 mm, of the component treated in the step S1; s3, an X-ray imaging technology is adopted for detecting the part, with the thickness ranging from 7.5 mm to 15 mm, of the component treated in the step S1; s4, the part, with the thickness larger than 15 mm, of the component treated in the step S1 is detected through the industrial CT technology; and S5, recording defect data detected in the steps S2 to S4. The method can be used for accurately, comprehensively and quickly detecting the internal defects of the titanium alloy bearing seat component formed by selective laser melting. 本发明属于增材制造领域，公开了一种激光选区熔化成型构件的检测方法。所述方法包
