Discussion Scanning Mode of Direct Laser Fabrication Quality Influence

The titanium alloy direct laser fabrication process, the collapse of a side issue has interference and preventing the forming quality and forming precision. This thesis mainly contain with of temperature field analysis and actual observation, by changing the scanning mode to solve this issue. The new scanning mode, dam-type, has a good property and proves that the direct laser fabrication parameters can be complete without change through the whole forming process, and puts the process of control simply.
