The Influence of Layer Thickness on the Tensile Properties of 3D Printed PLA

Abstract

Nowadays, 3D printing is gaining popularity in the manufacturing sector due to its ability to produce complicated shapes more quickly than conventional procedures. However, several relationships between printing parameters and factors remain unclear, necessitating further research to achieve the best results. Therefore, to enhance the usage of 3D printing technology, more information is needed. The printing parameters, such as infill pattern, infill density, infill thickness, temperature, and printing speed, need to be optimized to ensure good tensile properties for 3D printed parts. Although parameters like infill pattern and infill density have been extensively studied, the effect of layer thickness is less well-known. The study found that the layer thickness had an effect on the tensile properties of PLA samples.
