Abstract

In this study, the effect of various parameters of a single screw extruder on the rheology and mechanical properties of a polylactic acid (PLA) filament with a 1.75 mm diameter was investigated. The barrel temperature, nozzle and cooling bath temperature, screw speed, nozzle diameter, water bath length, and distance to the nozzle were the process variables. A Taguchi experimental design was implemented using an L8 orthogonal matrix with seven factors and two levels, and their influence on roundness and diameter were evaluated. Among the various processing parameters, the temperature of the cooling bath affected the roundness the most. The mechanical properties and surface roughness of the PLA filament were examined using a tensile test and nanofocus optical system, respectively. Moreover, to assess the filament's reliability and investigate its behavior further, the filament was used to print 0° plates, and then dog-bone samples were cut from them to evaluate the mechanical properties of the printed specimens. Finally, the results indicate that improved-roundness filaments of 0.004 mm can lead to enhanced mechanical properties in 3D-printed samples with 3.54 MPa.

制造工艺对长丝生产的影响及其对增材制造结构的影响研究。

研究了单螺杆挤出机各参数对直径1.75 mm聚乳酸（PLA）长丝流变学和力学性能的影响。筒体温度、喷嘴和冷却浴温度、螺杆转速、喷嘴直径、水浴长度和到喷嘴的距离是工艺变量。采用7因素2水平L8正交矩阵进行田口试验设计，考察其对圆度和直径的影响。在各加工参数中，冷却浴温度对圆度影响最大。采用拉伸试验和纳米聚焦光学系统分别测试了PLA长丝的力学性能和表面粗糙度。此外，为了评估长丝的可靠性和进一步研究其行为，使用长丝打印0°板，然后从其上切割狗骨样品，以评估打印样品的力学性能。最后，研究结果表明，在3.54 MPa的压力下，0.004 mm的圆度提高的细丝可以提高3d打印样品的力学性能。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
