本研究涉及聚合物增材制造（PAM），传统上用于快速成型操作。与注塑成型部件相比，PAM部件作为功能部件的使用仍然是微不足道的。这与其机械性能的退化和对PAM产品的相对贫乏的知识有关。Freeformer-Arburg机器中集成了一项独家的增材制造新技术[1]。它的灵感来自注塑成型技术，并使用由微小塑料液滴形成的层来制造塑料部件。在这项工作中，通过Freeformer PAM获得的热塑性聚合物部件的机械特性是23 ème Congrès Français de Mécanique里尔，28 Aotert Au 1 er Septembre 2017 2研究。通过单轴拉伸试验，通过改变一些制造参数，如印刷路径，评估的力学性能。然后，PAM和成型样品的力学性能进行了讨论。进行微观结构分析，以更好地了解制造工艺和最终机械性能之间的关系。最后，第一步有关建筑材料的地址，以优化其机械性能的目的。本部分将通过解决研究的双材料方面来完成。Mots clefs：Fabrication additive polymère，caractérisation mécanique，matériaux architecturés，optimization
The present study relates to the Polymers Additive Manufacturing (PAM), traditionally used for rapid prototyping operations. The use of PAM components as functional parts is still marginal compared to injection molded components. This is related to the degradation of their mechanical properties and the relatively poor knowledge on the PAM products. An exclusive new technology of additive manufacturing was integrated in the Freeformer-Arburg machine [1]. It was inspired from injection molding technology and creates plastic parts using layers built up from tiny droplets of plastic. In this work, the mechanical characterization of thermoplastic polymer parts obtained by Freeformer PAM is 23 ème Congrès Français de Mécanique Lille, 28 Août au 1 er Septembre 2017 2 studied. The mechanical properties are evaluated via uniaxial tensile tests by varying some manufacturing parameters such as the printing path. Then, the mechanical properties of both PAM and molded samples are discussed. Microstructural analyses were performed to better understand the relationship between the manufacturing process and the final mechanical properties. Eventually, a first step about architected materials is addressed, with the aim of optimizing their mechanical properties. This part will be completed by addressing the bimaterial aspect of the study. Mots clefs: Fabrication additive polymère, caractérisation mécanique, matériaux architecturés, optimisation
