The increase in accessibility of fused filament fabrication (FFF) machines has inspired the scientific community to work towards the understanding of the structural performance of components fabricated with this technology. Numerous attempts to characterize and to estimate the mechanical properties of structures fabricated with FFF have been reported in the literature. Experimental characterization of printed components has been reported extensively. However, few attempts have been made to predict properties of printed structures with computational models, and a lot less work with analytical approximations. As a result, a thorough review of reported experimental characterization and predictive models is presented with the aim of summarizing applicability and limitations of those approaches. Finally, recommendations on practices for characterizing printed materials are given and areas that deserve further research are proposed.
熔融沉积成型（FFF）机器的可及性增加，激发了科学界致力于理解用该技术制造的部件的结构性能。文献中已报道了许多表征和估计用FFF制造的结构的力学性能的尝试。关于打印部件的实验表征已有大量报道。然而，很少有人尝试用计算模型预测打印结构的性能，而用解析近似法的工作则更少。因此，本文对已报道的实验表征和预测模型进行了全面综述，旨在总结这些方法的适用性和局限性。最后，给出了关于表征打印材料的实践建议，并提出了值得进一步研究的领域。
