Vast improvements have been made to the capabilities of advanced manufacturing (AM), yet there are still limitations on which materials can effectively be used in the technology. To this end, parts created using AM would benefit from the ability to be developed from feedstock materials incorporating additional functionality. A common three-dimensional (3D) printing polymer, acrylonitrile butadiene styrene, was combined with bismuth and polyvinylidene fluoride via a solvent treatment to fabricate multifunctional composite materials for AM. Composites of varying weight percent loadings were extruded into filaments, which were subsequently 3D printed into blocks via fused filament fabrication. Investigating the material properties demonstrated that in addition to the printed blocks successfully performing as radiation shields, the chemical, thermal, and mechanical properties are suitable for AM. Thus, this work demonstrates that it is possible to enhance AM components with augmented capabilities while not significantly altering the material properties which make AM possible.

用于极端环境的聚合物复合材料的熔融长丝制造

先进制造 (AM) 的能力已经取得了巨大进步，但在该技术中可以有效使用哪些材料方面仍然存在限制。为此，使用 AM 创建的零件将受益于从包含附加功能的原料材料开发的能力。一种常见的三维 (3D) 打印聚合物丙烯腈丁二烯苯乙烯通过溶剂处理与铋和聚偏二氟乙烯结合，以制造用于 AM 的多功能复合材料。将不同重量百分比负载的复合材料挤出成细丝，然后通过熔融细丝制造将其 3D 打印成块。对材料特性的研究表明，除了印刷块成功地用作辐射屏蔽外，化学、热、和机械性能适用于AM。因此，这项工作表明，可以增强具有增强功能的 AM 组件，同时不会显着改变使 AM 成为可能的材料特性。
