Effect of process parameters on tensile strength of 3D printed PLA parts

Additive Manufacturing (AM), known as 3D printing, has transformed industrial production through precise layer-by-layer material deposition. However, the primary issue often encountered during the fabrication of parts using Fused Deposition Modeling (FDM) is the...
