Optimization of Printing Parameters for 3-D Printed PLA

In this work, 3D printed part of PLA was checked for dimensional accuracy and printing parameters were optimized for getting optimal design. For doing so we selected nozzle temperature and step size as printing parameters for optimization. Design of Experiment (DOE) was done using Minitab to check optimal parameters. We concluded that increasing the nozzle temperature increases the dimensional accuracy of the printed part and decreasing the step size will increase the dimensional accuracy
