The utility model discloses a variable-diameter spring, a 3D printing platform cushioning structure and a 3D printer, the variable-diameter spring comprises a spring main body, the diameter of a spring ring, located in the middle, of the spring main body is the smallest, and the spring main body is curled from the middle to the two ends to form a conical part with the diameter of the spring ring gradually increasing; and the conical part of the spring ring with the gradually increased diameter can be in a scroll shape after being completely compressed. On the premise that the effect of an original flat gasket is not affected, the technical effects that the installation time consumption can be reduced, the error probability is reduced, and the cost is optimized are achieved, and then the problems that in the prior art, a cushioning structure needs to be provided with a small and thin flat gasket, the installation difficulty is high, and the installation efficiency is low are solved. 本申请公开了一种变径弹簧、3D打印平台缓震结构及3D打
