【 摘 要 】

In order to satisfy the demand of the efficient and precise manufacturing of artificial bone, the research on the process of 3D printing is carried out for artificial bone material PEEK. Aiming at the high efficiency, low consumables and high storage modulus, response regression mathematical models of parameters are established and the optimized process parameters are obtained based on the Response Surface Methodology. The obtained optimal parameters of 3D printing are that the layer thickness is 0.43mm, the density of internal filling is 55.05% and the number of outer contour is 1.39. Verification experiment is carried out and its results are verified the correctness of optimization results and the regression model. This study provides the basis for the selection of process parameters for 3D printing of PEEK materials.
