Comparison of Two Scan Strategies Applied to the Selective Laser Melting

摘要：

In selective laser melting (SLM) processing, the residual stress will be occurred inside the melted layer inevitable, and the deformation will be made simultaneously. The laser scanning strategy determined the deformation magnitude and the shape residual stress profiles. In order to optimize the manufacture and reduce the deformation of manufactured metal layers, helix scan strategy and progressive scan strategy for selective laser melting technology have been developed. In the result, the helix scan strategy helps to decrease the deformation of melted layer more effectively.
