Metal Powder of Laser Rapid Prototyping and Manufacturing Based on Sintering Technology

s:As a key technology of rapid prototyping and manufacturing(RPM),rapid manufacturing of metal parts is a target of RPM.Based on the introduction of research status and technique characteristic of selective laser sintering of metal powder which is one of the most important contents of rapid prototyping technology,experiments on selective laser sintering of iron and nickel based on alloy powder are done and effects oftechnique parameters are studied systematically.In the end,adequate sinterˉing parameters of powder are derived and verified with sintering experiments.
