DETAILED DESCRIPTION OF THE INVENTION

[0023] Referring to FIGS. 1 and 2, a three-dimensional printer device is provided according to a preferred embodiment of the present invention. The three-dimensional printer device is used for curing a powder material 11. In the present embodiment, the three-dimensional printer device comprises a supplying apparatus 100, a formation table 200, a recycling trough 300, a powder collection cover 410, a distribution apparatus 400, a formation apparatus, a control unit (not illustrated), and a dust-escape prevention cover 600.

[0024] Referring to FIGS. 1 to 4, in the present embodiment, the supply apparatus 100 includes a tank 101, the tank 101 has a discharge hole 102, the tank 101 is provided to accommodate a powder material 11, an elevator 120 is disposed on a bottom portion 110 of the tank 101, the elevator 120 drives the bottom portion 110 to move upwardly and downwardly, so as to elevate and push the powder material 11 out of the discharge hole 102.

[0025] The formation table 200 includes a horizontal surface 210, and one side of the horizontal surface 210 is disposed adjacent to the supplying apparatus 100. The discharge hole 102 of the supplying apparatus 100 is at a level equal to or higher than the horizontal surface 210. The recycling trough 300 includes an opening 301, and the opening 301 is disposed on the other side of the formation table 200 opposite to the supplying apparatus 100.

[0026] The distribution apparatus 400 includes at least one sliding rail 401 and a roller 420. The roller 420 is pivotally disposed inside the powder collection cover 410. The roller 420 is disposed on the sliding rail 401. In the present embodiment, it is preferable that the roller 420 is disposed on two sliding rails 401 parallel to each other, and the roller 420 is perpendicular to each sliding rail 401. Each sliding rail 401 extends from the supplying apparatus 100 to the opening 301 of the recycling trough 300. Accordingly, the roller 420 and the powder collection cover 410 together can move across the formation table 200 between the supplying apparatus 100 and the recycling trough 300. When the distribution apparatus 400 moves across the formation table 200, the powder collection cover 410 covers at least a portion of the horizontal surface 210.

[0027] When the roller 420 enters the formation table 200 from the supplying apparatus 100, the roller 420 is rotatable to push the powder material 11, at an outlet of the supplying apparatus 100, to the horizontal surface 210. When the roller 420 is going across the horizontal surface 210, the roller 420 is rotatable to distribute the powder material 11 pushed by the roller 420, so the powder material 11 can cover the horizontal surface 210 with the same thickness.

[0028] Referring to FIGS. 1 to 3, the formation apparatus 500 is movable across the horizontal surface 210. The formation apparatus 500 can include an adhesive nozzle (not illustrated); an adhesive solution is ejected from the adhesive nozzle to cover the powder material 11 on the horizontal surface 210, thereby curing the powder material 11. The formation apparatus 500 can also include a light emitting element (not illustrated) for radiating light to the horizontal surface 210. The light emitting element is preferably an ultraviolet light emitting element. When the formation apparatus 500 is disposed above the horizontal surface 210, the light emitting element radiates light toward the horizontal surface 210, so that the powder material 11 covering the horizontal surface 210 receives radiation of light and cures.

[0029] The control unit is electrically connected to the supplying apparatus 100, the distribution apparatus 400 and the formation apparatus 500. By means of the control unit, the following steps are performed in sequence: driving the supplying apparatus 100 to provide the powder material 11, driving the distribution apparatus 400 to distribute the powder material 11 to cover the horizontal surface 210, and driving the formation apparatus 500 to cure the powder material 11 on the horizontal surface 210.

[0030] A baffle 411 is disposed in the powder collection cover 410, and the baffle 411 covers the roller 420 and is disposed inclinedly over the roller 420. After distribution is completed, the remaining powder material 12 is pushed to the baffle 411 to be collected inside the powder collection cover 410, thereby preventing the powder material 12 from escaping and attached to the formation apparatus 500 to affect formation.

[0031] Referring to FIGS. 1 to 4, the powder collection cover 410 forms at least one slope 412. In the present embodiment, the powder collection cover 410 preferably forms two slopes 412 parallel to each other at two ends with respect to the roller 420, a lower edge of each slope 412 is where the slope 412 is closest to the recycling trough 300, and the lower edge of each slope 412 is closer to the opening 301 of the recycling trough 300 than the powder collection cover 410.

[0032] Referring to FIGS. 5 to 7, the dust-escape prevention cover 600 is pivotally disposed on the recycling trough 300 and covers the opening 301 of the recycling trough 300, and the dust-escape prevention cover 600 preferably extends to form two protrusions 610 corresponding to the slope 412 of the powder collection cover 410.

[0033] Referring to FIGS. 8 and 9, when the powder collection cover 410 moves to be in front of the recycling trough 300, each slope 412 can correspondingly push each of the protrusions 610 on the dust-escape prevention cover 600 to thereby push the dust-escape prevention cover 600 away from the opening 301. When the powder collection cover 410 moves to be above the recycling trough 300, the remaining powder material 12 inside the powder collection cover 410 drops into the recycling trough 300 through the opening 301. When the powder collection cover 410 leaves the recycling trough 300, the dust-escape prevention cover 600 returns and covers the opening 301, thereby preventing the powder material 12 from escaping and attached to the formation apparatus 500 to affect formation during the process that the powder material 12 drops into the recycling trough 300. A restoration assembly 620 is disposed between the dust-escape prevention cover 600 and the recycling trough 300, the restoration assembly 620 can push the dust-escape prevention cover 600 to return and cover the opening 301. In the present embodiment, the restoration assembly 620 is preferably a spring 621, and two ends of the spring 621 are connected to the recycling trough 300 and the dust-escape prevention cover 600 respectively, so that the spring 621 can provide a force for making the dust-escape prevention cover 600 return; however, the present invention is not limited in this regard.

[0034] The three-dimensional printer device of the present invention can selectively include an inner block plate 630. In the present invention, the inner block plate 630 preferably extends from the dust-escape prevention cover 600. The inner block plate 630 is disposed in the recycling trough 300 and moves in association with the dust-escape prevention cover 600. When the dust-escape prevention cover 600 is opened away from the opening 301, the inner block plate 630 covers below the opening 301 of the recycling trough 300, thereby preventing the powder material 12 in the recycling trough 300 from escaping and attached to the formation apparatus 500 to affect formation.

[0035] It is to be understood that the above descriptions are merely the preferable embodiment of the present invention and are not intended to limit the scope of the present invention. Equivalent changes and modifications made in the spirit of the present invention are regarded as falling within the scope of the present invention.
