Investigation on Tensile and Compression Properties of 3D Printed PLA Material for Various Infill Percentage

This work aims to study the effect of process parameters such as infill percentage by keeping other parameters like printing temperature, nozzle diameter, layer height, top and bottom layer thickness, print bed temperature constant during preparation of the test specimens on mechanical properties of FDM printed parts. In the present project, specimen is made with PLA material having different infill percentages which is in turn tested for its mechanical properties like tensile, compression and impact strength. The results are compared with each other various combinations. Thus, this project is conducted to get the average of the strength and mechanical properties. One variable at a time approach has been adopted to carry out the work.
