Fused Deposition Modelling (FDM) is a widely used additive manufacturing process. It utilizes a variety of homogeneous and heterogeneous materials for product development. A new manufacturing process termed as Hybrid Fused Deposition Modelling (HFDM) has been used for the manufacture of various copper metal mesh (99.99% pure)/PLA (polylactic acid or polylactide) plastic composites. These products have been subjected to standardized experimental testing for evaluating properties such as tear resistance, tensile strength, water absorption, hardness, and flexural strength. The tests have been conducted to analyse the effectiveness of the HFDM process in manufacturing stronger composites compared to commercially available PLA and copper-infused PLA. Microstructural characterization has also been carried out to analyse the bond between the plastic and metal mesh layers. The results have been promising and demonstrate the effectiveness of HFDM to produce Cu/PLA composites with superior mechanical properties compared to parent FDM-printed PLA plastic as well as copper-infused FDM-printed PLA. Multiple copper mesh layers have been placed strategically within the test specimens to study their effect on the composites made by HFDM. The experimental results show that the process is capable of manufacturing high-quality composites (Cu/PLA) with tailored properties for various engineering applications.

熔融沉积建模（FDM）是一种广泛使用的增材制造工艺。它利用各种均质和异质材料进行产品开发。一种称为混合熔融沉积建模（HFDM）的新制造工艺已用于制造各种铜金属网（纯度为99.99％）/ PLA（聚乳酸或聚丙交酯）塑料复合材料。这些产品已经过标准化实验测试，以评估诸如抗撕裂性，拉伸强度，吸水率，硬度和抗弯强度等性能。与商用PLA和注入铜的PLA相比，已经进行了测试以分析HFDM工艺在制造更坚固的复合材料方面的有效性。还进行了微结构表征以分析塑料和金属网状层之间的结合。该结果令人鼓舞，并证明了HFDM能够生产比母体FDM印刷的PLA塑料以及注入铜的FDM印刷的PLA更好的机械性能的Cu / PLA复合材料。已在测试样品中策略性地放置了多个铜网层，以研究它们对HFDM制造的复合材料的影响。实验结果表明，该工艺能够制造出具有适合各种工程应用的定制性能的高质量复合材料（Cu / PLA）。该结果令人鼓舞，并证明了HFDM能够生产比母体FDM印刷的PLA塑料以及注入铜的FDM印刷的PLA更好的机械性能的Cu / PLA复合材料。已在测试样品中策略性地放置了多个铜网层，以研究它们对HFDM制造的复合材料的影响。实验结果表明，该工艺能够制造出具有各种工程应用量身定制的特性的高质量复合材料（Cu / PLA）。该结果令人鼓舞，并证明了HFDM能够生产比母体FDM印刷的PLA塑料以及注入铜的FDM印刷的PLA更好的机械性能的Cu / PLA复合材料。已在测试样品中策略性地放置了多个铜网层，以研究它们对HFDM制造的复合材料的影响。实验结果表明，该工艺能够制造出具有适合各种工程应用的定制性能的高质量复合材料（Cu / PLA）。
