Abstract

3D printing has evolved into a mature technology finding widespread industrial applications. The predominant method, fused deposition modeling (FDM), involves layer-by-layer deposition of melted thermoplastic to achieve the desired component shape. Common printing materials include polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate glycol (PETG), and thermoplastic polyurethane (TPU). While these materials possess excellent thermal and mechanical properties for producing high-quality specimens, there is still room for improvement in both efficiency and overall strength. The objective of the current study is to validate the concept that deliberately induced vibrations during 3D printing will reduce porosity to increase tensile strength. Specimens were printed with and without vibrations, using variations in infill level And vibrations as the main parameters to evaluate the impact on tensile strength. It was found that, for both PLA and ABS materials, increased vibration frequency decreased the porosity and correspondingly increased the tensile strength, indicating that low-frequency induced vibrations will decrease porosity, consequently increasing the overall tensile strength of the material.
