Research of the Virtual Prototyping Technology Based on Laser Processing

At present, laser processing has been widely used, but the traditional laser processing can not rapidly adapt to current market demands, so the virtual prototyping technology based on laser processing is put forward. In this paper, the research status of the virtual prototyping technology based on laser processing is summarized and the structure figure of laser processing virtual prototyping system is established. Then the virtual prototyping technology based on metal part direct rapid prototyping is studied, which includes the structure parameterization designs of coaxial powder feeding device and powder nozzle and the simulation of the gas-solid two-phase flow in the coaxial powder feeding device and the temperature distribution during the deposition process of metal powder.
