NOVELTY - The utility model claims a 3 D printing consumable drying box, comprising a base and an upper cover, the base and the upper cover are matched to form a shell, the shell is provided with a cavity, the cavity is provided with a consumable material tray for containing material, the shell is provided with at least one threading hole for the material to pass through, the cavity is provided with a drying component and a supporting frame, the graphene heating layer is attached to the heat conducting plate along the peripheral outline of the material consuming plate, the graphene heating layer is powered by the power supply assembly so as to heat, the utility model claims a 3 D printing consumable drying box, which can realize low-voltage driving, low current, low power consumption; the temperature in the box after electrifying the drying box is quickly increased to the needed temperature, reducing the preheating time, and the heat conducting plate is set along the peripheral outline of the material plate, the graphene heating layer is attached to the heat conducting plate along the peripheral outline of the material plate so as to make each place of the material heated uniformly, avoiding the problem that each drying effect of the consumable is not good, the effect of removing the whole moisture of the consumable is better.
