Abstract

3-D printing allows for rapid prototyping and manufacture of components in a cost effective and timely manner, becoming a popular technology for oceanographic and maritime engineering applications. However, 3-D printed components are at risk of accumulating marine biofouling. This study examined the antifouling (AF) performance of three Cu-containing 3-D printing polymer filaments for potential marine use. The amount of Cu present in each filament was the primary determinant of AF performance. The lowest Cu-content (30%) filament recording 29% biofouling cover after 1 month and near 100% cover after 3 months. These AF results were comparable to polylactide acid (PLA) and acrylonitrile butadiene styrene (ABS) polymer filament controls. The medium (50%) Cu-content filament remained largely free of biofouling until 3 months (where 48% coverage was observed), after which fouling cover increased to 100% by ∼12 months. The highest Cu-content (80%) filament remained free of all macrofouling for the entire 24 months of the experiment.

船用含铜熔融长丝制造(FFF)3-D打印聚合物长丝的防污性能

摘要

3-D打印可以以经济高效,及时的方式快速进行零件的原型制作和制造,从而成为海洋学和海事工程应用中的流行技术。但是,3-D打印的组件有累积海洋生物污垢的风险。这项研究检查了潜在的海洋用途的三种含铜的3-D打印聚合物长丝的防污(AF)性能。每根灯丝中的铜含量是AF性能的主要决定因素。最低铜含量(30%)的长丝在1个月后记录了29%的生物污损覆盖率,在3个月后记录了接近100%的覆盖率。这些AF结果可与聚乳酸(PLA)和丙烯腈丁二烯苯乙烯(ABS)聚合物长丝对照相媲美。中等含量(50%)的含铜长丝直到3个月(观察到48%的覆盖率)基本上都没有生物结垢,此后约12个月污垢覆盖率增加到100%。在整个实验的整个24个月中,最高含铜量(80%)的长丝没有任何宏观污垢。
