Description
[technical field]
The utility model relates to a kind of new-type laser output device printed for 3D.
[background technology]
Along with the development of 3D printing technique, the direct manufacturing technology of metal powder laser rapid shaping becomes the focus that everybody pays close attention to, metal powder laser rapid shaping leaves high-tech image to everybody, but at present circumstances, also some shortcomings are had, its medium velocity is the maximum topic that everybody carries slowly, so how to improve shaping efficiency, and playing the effective fan-out capability of laser becomes a problem that can further investigate.
At present, metal powder laser rapidform machine uses and simply focuses light path, laser scanning sinters, melting powder is all scan in fixing focus, we know that metal powder laser rapid shaping efficiency comparison is low, one of them main cause is, each sintering, the area of melting is little, in focal position, laser facula is minimum, the live width of so each scanning is also the thinnest, the thinnest hot spot is applicable to the scanning of part inside and outside contour, contour accuracy can be improved, and surface effect, but when exporting larger laser power in focal position, powder can by partial gasification, produce and splash, affect formed precision and density, the live width that the thinnest hot spot scans at every turn is narrow, the result scanned in focal position is exactly that shaping efficiency is low, effective fan-out capability of laser instrument can not be given full play to, and the result do not scanned in focal position to ensure parts profile precision and outer surface effect.
Therefore, be necessary to solve as above problem.
