METHOD FOR ADDITIVE MANUFACTURING OF THREE-DIMENSIONAL ARTICLES |
摘要 |
A method for forming at least one three-dimensional article through successive fusion of parts of a powder bed, which parts correspond to successive cross sections of the three-dimensional article, the method comprising the steps of: providing a model of the at least one three-dimensional article; applying a first powder layer on a work table; directing a first energy beam from a first energy beam source over the work table causing the first powder layer to fuse in first selected locations according to corresponding models to form a first cross section of the three-dimensional article, where the first energy beam is fusing at least a first region of a first cross section with parallel scan lines in a first direction; varying a distance between two adjacent scan lines, which are used for fusing the powder layer, as a function of a mean length of the two adjacent scan lines. |

1. A method for forming at least one three-dimensional article through successive fusion of parts of a powder bed, which parts correspond to successive cross sections of the three-dimensional article, said method comprising the steps of:
applying a first powder layer on a work table; directing a first energy beam from a first energy beam source over said work table so as to cause said first powder layer to fuse in first selected locations according to a corresponding model of said at least one three-dimensional article so as to form a first cross section of said three-dimensional article, where said first energy beam is configured to fuse at least a first region of a first cross section with two or more parallel scan lines in a first direction; and determining a distance between two adjacent of the two or more parallel scan lines, which are used for fusing said powder layer, as a function of a length of at least one of said two adjacent scan lines. |
