The optimization research of process parameters for Laser Direct Rapid Forming (LDRF) metal parts, is a research focus of rapid prototyping technology. The article discussed in detail for solving the optimum process parameters of LDRF technology for the selection approach of strategy of genetic algorithm, the quantitative relationship model was established between process parameters of forming pieces and the part density using neural network method , which process parameters are laser power (P), scanning speed (V), powder feeding rate (G), scan...
