Abstract

The invention provides an auxiliary online heating device and method for a fused deposition additive manufacturing system, the device comprises a bottom plate, an x-direction moving device, a y-direction moving device and a heating source, the heating source is installed on the x-direction moving device, the x-direction moving device is connected with the y-direction moving device, and the y-direction moving device is installed on the bottom plate; when the y-direction moving device is static, the x-direction moving device is started to reciprocate on the y-direction moving device, so that the heating source reciprocates in the x direction; and when the x-direction moving device is static, the x-direction moving device drives the heating source to reciprocate in the y direction through the movement of the y-direction moving device. The auxiliary heating source can be integrated in the cavity shell of the fused deposition system, and the situation that the overall size of the additive manufacturing system is increased due to the fact that a heat source is additionally added is avoided.

Description

technical field

[0001] The present invention relates to the technical field of additive manufacturing, in particular, to an auxiliary online heating device and method for a fused deposition additive manufacturing system. Background technique

[0002] Most of the external heating sources equipped in the current additive manufacturing system are integrated into the nozzle, and the path of the external heat source is coincident with the nozzle.

[0003] Since the external heating source equipped with the existing additive manufacturing system is integrated into the nozzle, the path of the external heat source is coincident with the nozzle, the heating range is small and the heating is uneven, and the heating area is limited by the printing path. The temperature difference between adjacent layers of the deposited material cannot be maintained at a small level, which in turn reduces the bonding quality between the fused deposited layers, resulting in unsatisfactory mechanical pro...
