熔融沉积建模（FDM）作为快速发展的增材制造技术已成功应用于多个行业。在本研究中，通过比较压缩测试中获得的 FDM 样品的强度和模量，研究了印刷层厚度、增强材料类型和碳化硅纳米线 (SiCnw) 刷涂层对压缩性能的影响。首先，打印层厚度决定了打印试件的强度，纯聚乳酸（PLA）、短碳纤维增强的PLA（Cf/PLA）、石墨烯增强的PLA（G/PLA）。结果表明，打印样品的强度和弹性模量随着打印层厚度的减小而增加。因此，在相同的印刷层厚度下，进一步研究不同增强类型对机械性能的影响。这表明由于碳纤维的高模量，打印的Cf/PLA具有最高的弹性模量，高达1.69GPa。最后，发现打印的 PLA 层之间的 SiCnw 刷层显着提高了压缩模量，并且从纯 PLA 到具有三个 SiCnw 刷层的 PLA 增长了 55.1%。
Fused deposition modeling (FDM) as a rapidly growing additive manufacturing technology is successfully applied to several industries. In this study, effects of printing layer thickness, reinforcement types, and silicon carbide nanowire (SiCnw) brushing layers on compressive properties are investigated by comparing the strength and modulus of the FDM specimens acquired from compression tests. First of all, the printing layer thickness determines the strength of the printed specimens, the pure polylactic acid (PLA), the PLA reinforced by short carbon fiber (Cf/PLA), and the PLA reinforced by graphene (G/PLA). The results indicate that both strength and elastic modulus of the printed specimens increase with the decrease of the printing layer thickness. Therefore, the effects of different reinforcement types on the mechanical properties are further investigated at the same printing layer thickness. It indicates that the printed Cf/PLA receives the highest elastic modulus up to 1.69 GPa due to the high modulus of carbon fiber. Finally, the SiCnw brushing layers between the printed PLA layers are found to significantly increase the compressive modulus and there is a growth of 55.1% from pure PLA to PLA with three SiCnw brushing layers.
