Abstract In recent years, there has been a logarithmic interest in three-dimensional printing technologies. This technique has made it possible to make more intricately shaped parts of superior quality, allowing for use in a variety of industries, including aircraft, automobiles, and ships. This study characterized the materials and assessed the mechanical features of PLA, PETG, and ABS materials generated at various raster angles. The strength ratios of the various materials have been found to fluctuate when the raster angles change. The PLA parts created at a picture raster angle of 45° had the maximum tensile strength. ABS material created with a picture raster angle of 45° has been shown to have the best energy absorption, and PLA material made with a raster angle of 45° has the best performance compressive strength. When bending strength was evaluated, it was found that samples of ABS made with a raster angle of 0–90° had the greatest value. The SEM micrographs were obtained, and the tensile test was used to examine the fracture behavior of the materials. As a result, it has been found that materials created using various raster angles can have various strength values from one another.
