The utility model provides a spray head assembly and 3D printing equipment applying the same. The spray head assembly comprises a nozzle unit and an optical scanner, the optical scanner comprises a first mark surface, and the first mark surface is configured to be arranged towards a forming platform of the 3D printing equipment. The optical scanner comprises a first light emitting assembly, a second light emitting assembly and a light collecting assembly. The first light emitting assembly is used for emitting laser with a first optical axis, and an included angle is formed between the first optical axis and the first mark surface. The second light emitting assembly is used for emitting illumination light and is exposed from the first mark surface. The light collecting assembly, the first light emitting assembly and the second light emitting assembly are arranged at intervals, and the light collecting assembly is exposed by the first mark face and used for collecting light signals. And the light acquisition as
