In order to discuss the effect of laser energy density on the dimension of nylon12/HDPE (high density polyethylene) product,experiments of sintering nylon12/HDPE were carried out with CO2 laser based on the selective laser sintering technology.The microstructure of laser-sintering nylon12/HDPE was examined by means of scanning electron microscopy.It is concluded that warping will increase with the ratio of power/velocity (P/v) increasing.Optimum laser energy densitv P/v=0.8% while warping is about 0.4mm.This study is helpful to sinter the composite of nylon powder.
