熔融沉积成型（FDM）受到应用特定功能材料的可用性的限制。在这里，我们说明了非传统的聚合物纳米复合材料（CNT和石墨烯基聚对苯二甲酸丁二醇酯（PBT））的商业可用的桌面3D打印机上的打印，导致打印导电结构。评价了聚合物纳米复合材料在3D打印前后的可打印性、导电性和机械稳定性。结果表明，3D打印的PBT/CNT物体具有更好的导电和机械性能，并且比3D打印的PBT/石墨烯结构具有更好的性能。除此之外，印刷多于一种材料（多材料）和使用研磨导电填料（即，CNT和石墨烯）也进行了讨论。总的来说，这项研究表明，商用桌面3D打印机可用于制造低成本的功能对象。(C)2017作者由Elsevier Ltd.发布。这是CC BY许可下的开放获取文章
Fused deposition modeling (FDM) is limited by the availability of application specific functional materials. Here we illustrate printing of non-conventional polymer nanocomposites (CNT- and graphene-based polybutylene terephthalate (PBT)) on a commercially available desktop 3D printer leading toward printing of electrically conductive structures. The printability, electrical conductivity and mechanical stability of the polymer nanocomposites before and after 3D printing was evaluated. The results show that 3D printed PBT/CNT objects have better conductive and mechanical properties and a better performance than 3D printed PBT/graphene structures. In addition to that, printing more than one material (multi materials) and challenges in using abrasive conductive fillers (i.e., CNT and graphene) are also discussed. Overall this study demonstrates that a commercially available desktop 3D printer can be used to fabricate low-cost functional objects. (C) 2017 The Authors. Published by Elsevier Ltd.
