A material supply amount is controlled accurately. A material supply apparatus includes a hopper that stores a material used for shaping a three-dimensional laminating and shaping object, a columnar recoater having a rotational shaft, and a driver that rotates the columnar recoater while moving the columnar recoater in a horizontal direction perpendicular to the rotational shaft. The recoater has a plurality of grooves in a direction along the rotational shaft that are formed on an outer circumferential surface, and temporarily store the material supplied from the hopper.

A powder is spread in two directions, that is, the advancement and retraction directions of a powder recoater. The powder recoater according to this invention includes a hopper that stores a powder, and a cylindrical powder supplier that has a side surface close to or in contact with the bottom surface of the hopper and includes a supply path for the powder. The powder recoater according to this invention further includes a pivoting unit that causes the powder supplier to pivot. In the powder recoater according to this invention, the center axis of the supply path is displaced from the center axis of the powder supplier in the radial direction of the powder supplier.
摘要:
The overall structure of a three-dimensional laminating and shaping apparatus is downsized. There is provided a three-dimensional laminating and shaping apparatus comprises a case that houses a shaping table, at least two arms that are extended in a horizontal direction of the case and coupled to the shaping table to support the shaping table, and a moving unit that moves the at least two arms in a vertical direction of the case. The case includes a slit that is formed on a side wall of the case with extending in the vertical direction of the case, and through which one of the at least two arms moving in the vertical direction of the case passes, a tape-like seal member that has upper and lower ends fixed inside the side wall with extending in the vertical direction of the case to prevent leakage of powder particles to outside of the case through the slit by covering the slit, and a winding structure in which the tape-like seal member winds so that the tape-like seal member extends to inside of the case in an inwardly convex shape at a position where an end of the one of the at least two arms passes through the slit in the side wall of the case.
摘要:
This invention quickly supplies a predetermined amount of powder from a hopper to a recoater. A powder supply apparatus includes, as its feature, a hopper, a powder spreader, a powder replenisher, and a pivoting unit. The hopper of the powder supply apparatus stores a powder. The powder spreader spreads the powder on a shaping surface. The powder replenisher of the powder supply apparatus is provided between the hopper and the powder spreader, and replenishes the powder spreader with a predetermined amount of powder. The pivoting unit of the powder supply apparatus causes the powder replenisher to pivot.
