[0006] A heat exchange heating device for 3D printing equipment includes a frame, and also includes a blowing box, a suction box, a warm air blower, a plurality of heating lamps and a multi-point temperature sensor. The blowing box and the suction box are correspondingly installed on both sides of the printing platform, so that the blowing port of the blowing box corresponds to the suction port of the suction box; the blowing box and the suction box are connected and communicated through a hot air circulation pipeline; the warm air blower is installed on the hot air circulation pipeline; a plurality of the heating lamps are all installed on the frame and above the printing platform; the multi-point temperature sensor is installed on the frame.

[0007] By adopting the above technical solutions, the beneficial effects of the utility model are as follows:

[0008] 1) Nitrogen heated by the blowing port is blown out, and the suction port sucks air to form a hot air field. The hot air field exchanges heat with the powder on the printing surface to heat the powder at the printing position, realizing uniform heating;

[0009] 2) The multi-point temperature sensor detects the temperature of the entire printing area. When the temperatures at each position of the area are inconsistent, the heating lamps at the corresponding positions are used for auxiliary heating to make the temperatures of the temperature field consistent.

[0010] Furthermore, it also includes a controller. The plurality of heating lamps are evenly distributed; the multi-point temperature sensor is electrically connected to the controller, and the controller is electrically connected to the plurality of heating lamps.
