The invention relates to the technical field of 3D printing, and discloses an extruder for 3D printing equipment, comprising a base and a motor with a control switch. A water storage tank, a gas storage tank and a feeding syringe are fixedly connected to the base. A first rotating shaft and a second rotating shaft are arranged in the water storage tank, the lower end of the first rotating shaft is fixedly connected with a first fan, the upper end of the second rotating shaft is provided with a second fan, and the lower end of the second rotating shaft extends into the gas storage tank and is rotatably connected with a disc. The feeding syringe comprises a needle, a barrel and a lightweight pressure tube with a hollow interior, and the upper end of the lightweight pressure tube is communicated with the bottom of the gas storage tank through an air pipe, which comprises a hard tube and a corrugated tube connected with the hard tube. The invention counteracts the vibration of the base caused by the motor, making the path of clay spraying straight and ensuring the quality of printed products.
