The Preparation of WPC for SLS Rapid Prototyping and Manufacturing

“…Its work processes are as follows: first, a 3D Entity CAD model for the workpieces is established in a computer, and it is treated by slicing with a layering software in order to get information on each layer which is converted into electronic signals to control the laser scanning system [2]; second, a thin layer of powder is spread evenly over the working table before the selective sintering to the laminated contours of the workpieces by the laser beams controlled by a computer. The powder exposed to the laser beams then melt and get bonded during the cooling process, forming a layer; the next step is to lay out the powder and apply scanning sintering layer by layer until the last layer is finished and the 3D entity model is created; and finally, after the residual powder is removed, we can get the parts by polishing, drying and wax impregnation [3]. At present most of the raw materials for SLS are polymers, coated papers, metallic powders, textile fibers and ceramic composites.…”
