[0036] In this embodiment, teeth are printed by the 3D printing device 102, and the teeth are printed and formed on the frustum 108. When it is necessary to dry them, the two limiting pins 119 are pulled out from the inside of the limiting holes 121, and then the sealing plate 106 is covered through the handle 107 to seal the protective cover 101, providing a stable negative pressure environment and a controllable blowing air flow for the air drying operation.

The drying fan 115 is arranged through the two groups of connecting rods 114 in the through groove 113 formed on the outer surface of the mounting plate 111, which can enable the drying fan 115 to better maintain an appropriate distance from the finished product, thereby improving the drying efficiency. Starting the two driving motors 118 can drive the reciprocating lead screws 117 to rotate. The two reciprocating lead screws 117 drive the two rack plates 123 to move reciprocally. While the two rack plates 123 are moving, they are engaged with multiple half-face gears 122, so as to drive the drying fan 115 to adjust the up-and-down angle through the two groups of connecting rods 114, improving the drying surface of the finished product and effectively accelerating the drying operation. One side of the two rack plates 123 is movably embedded in the interior of the chute 124 through the slider 125. Therefore, the rack plate 123 can only move up and down and will not rotate with the reciprocating lead screw 117.
