Consumable drying mechanism for 3D printing

The utility model relates to a consumable drying mechanism for 3D (three-dimensional) printing, which comprises a base, a cover, a consumable tray, a graphene heating mechanism, a ventilation mechanism, a lifting support mechanism and a sealing mechanism. The consumable material disc, the graphene heating mechanism, the ventilation mechanism and the lifting supporting mechanism are arranged in the sealed space, the graphene heating mechanism comprises a heating table, a heater, a graphene heating layer and a heat conducting plate, and the ventilation mechanism comprises an exhaust inlet, an exhaust pipe, an exhaust fan and an air outlet. And the lifting supporting mechanism comprises a telescopic air cylinder, a lifting table and a connecting plate, the graphene heating layer has the characteristics of being high in heating speed, high in electricity-heat conversion efficiency and the like, then uniform heating of the heat conduction plate is facilitated, and through arrangement of the lifting supporting mech
