| Abstract: | Nylon 12 composite powder with low melting point prepared by the method of solvent settling out is used as the basic material and it is modified by fillers to obtain powder for selective laser sintering. With the ortho-design experiment method, the sintering process of nylon composite powder is optimized. On this basis,the effects of sintering process parameters on properties of the parts are analyzed. Noted by SEM, this method can make nylon composite power sinter with high powder density, precision and mechanical properties. |
