Pine/polyethersulfone ( PES) wood-plastic composite was prepared in the mass ratio of 1 ∶4.The experiments of wood-plastic parts were performed by selective laser sintering using the HRPS-ⅢA rapid prototyping machine.The thermal performance and microstructure of composite were characterized by differential scanning calorimeter ( DSC) , fourier trans-form infrared spectrometer ( FTIR) and scanning electron microscopy ( SEM) .The mechanical properties of sintered parts were improved by optimizing process parameters by Minitab software.The mechanical properties of wood plastic composite reached the optimal value under laser power of 8.8 w, scanning speed of 1 800 mm/s, sintered spacing of 0.1 mm, and the layer thickness of 0.1 mm, respectively.
