Research Progress on Process Optimization of 3D-printed Poly(ether ether ketone)by Fused Deposition Modeling

聚醚醚酮(PEEK)因其具有耐高温、耐腐蚀、高硬度、质量轻、耐疲劳等特点,被广泛应用于机械制造、航空航天等高端领域,可作为金属材料的替代产品。随着科技的进步,PEEK材料被用于精密机械和复杂材料的制造原料,传统注塑成型已无法满足微精密、高强度零部件的需要,限制了其进一步发展和应用。然而,将3D打印技术与PEEK材料体系结合为其制造和应用的发展提供了全新的思路,其中熔融沉积成型(FDM)3D打印PEEK技术的发展尤其突出,但通过FDM成型PEEK的工艺参数因其制造方法的局限性而尚未形成统一标准。因此,本文通过综述近年来FDM工艺参数对PEEK力学性能和结晶度影响的相关研究,总结出FDM打印PEEK的最佳工艺参数,并对FDM打印PEEK的发展前景进行展望。

Due to the excellent properties of high temperature resistance,corrosion resistance,high hardness,light weight,fatigue resistance and so on,poly(ether ether ketone)(PEEK)is widely used in machinery manufacturing,aerospace and some other crucial applications instead of metals.With the development of science and technology,PEEK has already been used for precision manufacturing machinery and constructing complex structures.However,traditional injection molding cannot meet the needs for fabricating micro-precision and high-strength parts,which may limit the further development and application of PEEK.Nevertheless,the combination of PEEK and the fast-growing 3D printing techniques provides a novel thought for the development of its manufacture and application.Among the 3D printing techniques,fused deposition modeling(FDM)has been highlighted in fabricating PEEK depend on its unique advantages.But limited by the manufacturing method,the process parameters of FDM-printed PEEK have not formed a unified standard yet.Therefore,this work summarized researches about the effect of process parameters on the mechanical properties and crystallinity of FDM-printed PEEK in recent years,concluded the optimized process parameters of FDM printed PEEK,and finally provided a prospection in its development.
