摘要

本研究的主要目的是优化可用于FDM（熔融沉积建模）生产方法的印刷参数，通过拉伸试验获得PLA（聚乳酸）长丝的最低生产时间和最佳印刷参数。FDM机器中可使用的印刷参数，如挤出机温度、床层温度、层高度、印刷速度、行进速度、填充物和壳数，都被考虑在内进行优化。此外，来自ASTM（美国试验与材料学会）D638标准的拉伸试样是通过具有上述修改的印刷参数的PLA细丝制造的。通过生产过程中记录的时间和生产后的拉伸测试结果，找到了PLA产品的最佳印刷参数。因此，通过本研究，可以找到最佳的PLA长丝印刷参数及其时机。

Optimization of 3D Printing Process Parameters of Polylactic Acid Filament Based on the Mechanical Test

The main objective of this research study is to optimize the printing parameters that can be used in the FDM (fusion deposition modeling) production method to obtain the lowest production time and best printing parameter of PLA (polylactic acid) filament with the tensile test. The printing parameter that can be used in FDM machines such as extruder temperature, bed temperature, layer height, printing speed, travel speed, infill, and shell count is taken into account for optimization. In addition, the tensile specimens from ASTM (American Society for Testing and Materials) D638 standard were manufactured by PLA filament with the above-modified printing parameters. The best printing parameters for PLA products were found by the time recorded during production and tensile test results after production. Thus, through this research, one can find the best PLA filament printing parameters and their timing.

期刊介绍： International Journal of Chemical Engineering publishes papers on technologies for the production, processing, transportation, and use of chemicals on a large scale. Studies typically relate to processes within chemical and energy industries, especially for production of food, pharmaceuticals, fuels, and chemical feedstocks. Topics of investigation cover plant design and operation, process design and analysis, control and reaction engineering, as well as hazard mitigation and safety measures. As well as original research, International Journal of Chemical Engineering also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
