Beschreibung
Zusammenfassung:	The invention belongs to the field of measurement rake manufacturing, and particularly relates to a miniature measurement rake for a wind tunnel test, and a 3D printing method thereof. The measurementrake comprises: a measurement rake head, a measurement rake main body, a measurement rake base, a thermocouple wiring groove and a plurality of internal vent pipes; the measurement rake head, the measurement rake main body and the measurement rake base are sequentially connected; the plurality of internal vent pipes are disposed in the measurement rake head and extend into the measurement rake main body; and the thermocouple wiring groove extends from the measurement rake head onto the measurement rake main body. Through the 3D printing technology, the degree of freedom of the mechanical design of the measurement rake can be improved, the size of the measurement rake is effectively controlled, and the manufacturing time of the measurement rake is shortened; and a thermocouple and a pressure measurement pipe are i
