由复合材料制成的物体的增材制造是对高技术应用非常感兴趣的新兴技术，其允许快速且精确地制造具有调谐特性和很少几何限制的功能物体。在此，我们报道了通过溶液浇铸合成均匀复合材料，其中嵌入聚合物中的气体雾化金属颗粒的数量可调。复合材料被挤出成细丝，通过熔融沉积成型进行3D打印。所得结果表明，复合材料的填充因子，适合于获得连续和灵活的长丝，是强烈的颗粒大小及其分布的影响。磁力测量法是一种耗时短、能准确定量磁性复合材料填充因子的技术。此外，复合材料和长丝的磁性能的分析表明，在加工过程中没有恶化的颗粒。报道的加工技术被证明适用于生产金属基长丝，用于3D打印具有不受限制形状的零件，并在航空和航天领域具有潜在的适用性。
Additive manufacturing of objects made of composite materials is an emerging technology of great interest for high-technological applications allowing fast and precise fabrication of functional objects with tuned properties and few geometrical restrictions. Herein, we report on the synthesis by solution casting of homogeneous composites with tuned amount of gas-atomized metallic particles embedded in polymer. Composites were extruded into filaments for 3D-printing by Fused Deposition Modeling. The obtained results reveal that composites filling factor, suited to obtain continuous and flexible filament, is strongly influenced by particle size and its distribution. Magnetometry appears as a low-time consuming technique for accurately quantifying the magnetic composites filling factor. Moreover, the analysis of magnetic properties of composites and filaments revealed no deterioration of particles during processing. The reported processing techniques were demonstrated to be suitable to produce metal-based filaments for 3D-printing of pieces with non-restricted shape and potential applicability in aeronautics and aerospace sectors.
