Study on Mechanical Properties Enhancement of Post Processing WPC Powder Selective Laser Sintering Parts

Abstract:

In this paper, Wood-Plastic Composite(WPC) is successfully developed to make parts by Selective Laser Sintering(SLS) rapid prototyping (RP) process according to its advantages, such as green biological, wood texture and recycled, but the most important advantage is low-cost. With optimal design of components, the parts made by WPC have good mechanical properties as well as with good laser sintering properties. In order to further improve the mechanical properties of the parts, the post-processing–infiltrating with wax–is introduced. Through post-processing, the void fraction is decreased from from 51% to 7%, the mechanical properties are significantly improved, the average tensile strength, bending strength, impact strength are 1.214 MPa, 2.73 MPa and 1.4125 kJ/m2, compared with those without post processing, the tensile strength is 87 times, the bending strength is 4.7 times and impact strength is 2.5 times, respectively.
