The Preparation of WPC for SLS Rapid Prototyping and Manufacturing
The high cost of the raw materials and non-recycling use are the two main problems which restrict the development and extension of the SLS rapid prototyping.Firstly this paper did some theoretical analysis on the characteristics of wood flour,hot melt adhesive and other components.Then,through experimental comparison,using SEM to do microcosmic study and actual processing in laser shaper,this paper got a new formula of WPC for SLS.It is proved by the experiments,the WPC according to this formula is green environmental protection,degradable and can be recycled.Also,it can meet the processing requirements of SLS.The shape precision of the formed parts is high,the relative warping rate is only 0.26％～0.45％,the roughness is less than 0.03mm,and the parts reached a certain mechanical index.The tensile strength can reach a maximum of 0.014MPa and shock strength can reach a maximum of 0.954kJ/m2 .It provides the basis for the further post-processing to enhance the mechanical properties.
