Abstract


The objective of the present study is to examine the parameters employed in the robot-assisted 3D printing process. These parameters analysed include aspects such as Infill percentage, Layer thickness, and Raster angle. After the robotic 3D printing process, a test specimen is tested using standard D638-14 in a tensile testing machine, where an increasing axial force will be applied to the specimen, typically until failure, and the resulting variations will be documented. The stress/strain curve generated will demonstrate how the material reacts to the applied forces. Experiments involving robotic 3D printing with PLA and PETG materials revealed that the Ultimate Tensile Stress values for the PLA material were found to be higher than the corresponding PETG material.
