Additive technologies using Fused Deposition Modeling (FDM) technology are currently a promising tool for the production of polymeric multicomposites. This paper presents the results of a static 3-point bending test carried out on 3D printed samples of the PLA-TPU composite. The article also discusses initial vibrodiagnostic research and Finite Element Method (FEM) analysis of the 3D-printed composite bushings. The data obtained from FEM analysis served as input data for motion simulation analysis, where the influence of the stiffness of the suspension on the trajectory has been verified.
使用熔融沉积建模（FDM）技术的增材制造技术目前是生产聚合物多复合材料的一种很有前景的工具。本文展示了对聚乳酸-热塑性聚氨酯（PLA-TPU）复合材料的3D打印样品进行静态三点弯曲试验的结果。文章还讨论了对3D打印复合衬套的初步振动诊断研究和有限元法（FEM）分析。从有限元分析获得的数据用作运动模拟分析的输入数据，其中验证了悬架刚度对轨迹的影响。
