摘要

具有优异比强度的轻量化产品在汽车、航空航天、生物医学、体育等众多应用中都有很大的需求。这项工作的重点是使用蜂窝三维(3D)打印工艺制造轻质产品。在这项工作中，使用二氧化碳饱和丙烯腈-丁二烯-苯乙烯(ABS)长丝的3d打印技术，在单个泡沫长丝中开发了连续的微细胞形态。得到了平均细胞尺寸为6 ~ 1040µm的微细胞结构。印刷参数的影响;研究了喷嘴温度、进料速度和流量对不同水平泡沫特性和细胞形态的影响。讨论了所观察到的各种泡沫挤出物的不规则性。

Solid-state foaming of acrylonitrile butadiene styrene through microcellular 3D printing process

The lightweight products with superior specific strength are in great demand in numerous applications such as automotive, aerospace, biomedical, sports, etc. This work focussed on the manufacturing of lightweight products using the cellular three dimensional (3D) printing process. In this work, the continuous microcellular morphology has been developed in a single foamed filament using 3 D printing of carbon-di-oxide (CO2) saturated acrylonitrile butadiene styrene (ABS) filaments. The microcellular structures with average cell size in the range of 6–1040 µm were developed. The influence of printing parameters; nozzle temperature, feed rate, and flow rate on the foam characteristics and cell morphology at different levels were investigated. The different kinds of observed foamed extrudate irregularities were discussed.
