Abstract
The present invention relates to a powder distribution device that can uniformly distribute powder using powder flow due to the weight of the powder itself, and a 3D printing device including the same. The powder distribution device of the present invention comprises a powder distribution unit that includes: an outer frame having an empty powder material inlet port; and at least one distribution plate disposed inside the outer frame to disperse introduced powder, wherein the powder can be broken down using the powder flow without additional power from a feed screw, a motor, or the like.
Claims13
A powder distribution device for supplying powder to a powder-based 3D printing device, the powder distribution device comprising:
- a powder distribution unit including an outer frame having a powder material inlet port and at least one distribution plate disposed in the outer frame and distributing introduced powder,
- wherein the distribution plate is disposed to be spaced apart by a predetermined interval from a powder discharge surface from which powder is discharged,
- wherein the distribution plate has an inclined surface on two of its side surfaces, the inclined surface guiding powder discharged through the powder discharge surface to fall to a lower side of both side surfaces,
- wherein a plurality of through-holes are formed in the inclined surface of the distribution plate so that the powder passes through the distribution plate and falls downward, and
- wherein a diameter of the through-holes formed in the inclined surface of the distribution plate gradually increases in a downward direction.
A powder distribution device for supplying powder to a powder-based 3D printing device, the powder distribution device comprising:
- a powder distribution unit including an outer frame having a powder material inlet port and at least one distribution plate disposed inside the outer frame and distributing the introduced powder,
- wherein the distribution plate has an inclined surface branching from a powder discharge surface to both sides to distribute powder discharged through a powder discharge surface, and
- wherein the distribution plate has a powder discharge hole formed between the outer frame and the inclined surface of the distribution plate and between the inclined surfaces of both sides of the distribution plate.
