Document Type and Number:
WIPO Patent Application WO/2023/248524
Kind Code:
A1
Abstract:
A three-dimensional fabrication device 10 comprises: a lamination roller 31 that is configured as rotatable and provided at a predetermined height above a supply table 42 and a fabrication table 52; a drive device 33 that rotates the lamination roller 31; and a movement device 20 that moves the lamination roller 31 at least between over the supply table 42 and over the fabrication table 52. The three-dimensional fabrication device 10 moves the lamination roller 31 at least from over the supply table 42 to over the fabrication table 52, and forms a layer 210 of a powder material 200 upon the fabrication table 52. After forming the layer 210 of the powder material 200, the three-dimensional fabrication device 10 moves the lamination roller 31 at least to over the supply table 42, while rotating the lamination roller 31 in the direction of travel of the lamination roller 31 as the lamination roller 31 is moved.
