The invention discloses a forming cavity of laser additive manufacturing equipment and application of the forming cavity. The invention relates to the technical field of laser additive manufacturing. The forming cavity is sequentially divided into a forming area, a powder removing area and a sintering area from bottom to top. The forming area is provided with a lifting workbench, the lifting workbench comprises a telescopic supporting frame and a metal base plate arranged on the telescopic supporting frame, the telescopic supporting frame is arranged at the bottom of the forming area, and a vibrator is arranged on the bottom face of the working base plate. An induction sintering furnace is arranged in the sintering area, thermocouple wires on the upper portion of the induction sintering furnace are closed, and thermocouple wires on the two sides of the lower portion of the induction sintering furnace make contact with the metal substrate rising to the height to ensure that a circuit is smooth; and a laser wor
