Abstract

In a three-dimensional laminating and shaping apparatus, a material is quantitatively spread without clogging a supply port with the material. The three-dimensional laminating and shaping apparatus includes a material spreader that spreads a material of a three-dimensional laminated and shaped object on a spread surface, and includes at least one tapered portion in which a diameter decreases from an upstream side to a downstream side. The three-dimensional laminating and shaping apparatus also includes at least one vibration ball that is arranged in the tapered portion of the material spreader and vibrates, and a vibration controller that controls vibration of the vibration ball.

First claim

1 . A three-dimensional laminating and shaping apparatus comprising:
a material spreader that spreads a material of a three-dimensional laminated and shaped object on a spread surface, and includes at least one tapered portion in which a diameter decreases from an upstream side to a downstream side; at least one vibration ball that is arranged in said tapered portion and vibrates; and a vibration controller that controls vibration of said vibration ball.

2 . The three-dimensional laminating and shaping apparatus according to claim 1 , wherein
said material spreader includes a first tapered portion and a second tapered portion on the downstream side of said first tapered portion, and a first vibration ball is arranged in said first tapered portion and a second vibration ball is arranged in said second tapered portion.

3 . The three-dimensional laminating and shaping apparatus according to claim 1 , wherein said material spreader includes
an outer cylinder, and an inner cylinder that is detachably attached inside said outer cylinder and stores the material.

4 . The three-dimensional laminating and shaping apparatus according to claim 1 , further comprising:
a storage that detachably stores said material spreader.

5 . The three-dimensional laminating and shaping apparatus according to claim 1 , wherein a diameter of said first vibration ball is larger than a diameter of said second vibration ball.

6 . The three-dimensional laminating and shaping apparatus according to claim 1 , wherein a detachable attachment is provided in a distal end portion of said material spreader.

7 . A control method of a three-dimensional laminating and shaping apparatus including a material spreader that spreads a material of a three-dimensional laminated and shaped object on a spread surface and includes at least one tapered portion in which a diameter decreases from an upstream side to a downstream side, and at least one vibration ball that is arranged in the tapered portion and vibrates, the method comprising:
controlling vibration of the vibration ball.

8 . A non-transitory computer readable medium storing a control program of a three-dimensional laminating and shaping apparatus including a material spreader that spreads a material of a three-dimensional laminated and shaped object on a spread surface and includes at least one tapered portion in which a diameter decreases from an upstream side to a downstream side, and at least one vibration ball that is arranged in the tapered portion and vibrates, the program for causing a computer to execute a method, comprising:
controlling vibration of the vibration ball.
