随着熔丝制造（FFF）3D打印机中使用的常见和新型聚合物原料在消费者和工业环境中变得越来越普遍，彻底调查、表征和了解这些产品的独特排放特征至关重要。这项工作贡献了独特的见解与金属，陶瓷或碳质颗粒添加剂的聚合物复合材料原料的影响，在各种打印条件下，包括打印温度的各种长丝的颗粒排放。除了按照ANSI/CAN/UL 2904方法对颗粒尺寸和浓度进行主动表征外，颗粒取样和随后通过扫描电子显微镜进行的分析还揭示了可能具有重要健康影响的团聚行为。具体而言，某些长丝（包括丙烯腈-丁二烯-苯乙烯共聚物（ABS）和乙二醇改性聚对苯二甲酸乙二醇酯（PETG））产生的细颗粒（0.3-2.5 μm）是通过排放的超细颗粒团聚而形成的，而不是由连贯的初级颗粒组成;因此，吸入后这些颗粒的运输和行为可能不符合微米级颗粒的预期模式。类似于含碳添加剂的结构（例如，石墨烯和纳米管）也通过在印刷含有碳质先进材料的细丝期间的空中取样而被捕获。
It is critical to thoroughly investigate, characterize, and understand the unique emission profiles of common and novel polymer feedstocks used in fused filament fabrication (FFF) 3D printers as these products become increasingly ubiquitous in consumer and industrial environments. This work contributes unique insights regarding the effects of polymer composite feedstocks with metal, ceramic, or carbonaceous particle additives on particulate emissions in a variety of filaments under various print conditions, including print temperature. In addition to active characterization of particulate size and concentration following the ANSI/CAN/UL 2904 method, particulate sampling and subsequent analysis by scanning electron microscopy revealed agglomeration behavior that may have important health implications. Specifically, fine particles (0.3–2.5 μm) generated by certain filaments including acrylonitrile butadiene styrene (ABS) and glycol‐modified poly(ethylene terephthalate) (PETG) are shown to be formed via agglomeration of emitted ultrafine particles rather than composed of coherent primary particles; accordingly, transport and behavior of these particulates after inhalation may not follow expected patterns for micrometer‐sized particles. Structures resembling carbonaceous additives (e.g., graphene and nanotubes) were also captured by airborne sampling during printing of filaments containing carbonaceous advanced materials.
