Abstract
3D printing is one of the emerging technologies in the manufacturing sector, and polymer materials play a vital role in the raw material of the additive manufacturing sector. This research explores reducing the production time by testing and analyzing the microstructure of the different polylactic acid (PLA) filament polymer samples. For this purpose, 15 pieces of ASTM (American society for testing and materials) D638 tensile samples with polylactic acid (PLA) filaments have been used exclusively with five different sets of modified process parameters in slicing software of 3D printing technology. The results of this research reveal the best PLA filament FDM production method in terms of time, mechanical strength, and FESEM analysis comparing all the results.
