Abstract
It is well known that the manufacturing process has a direct influence on the mechanical
properties of elaborated material such as strength resistance, fatigue life, corrosion resistance,
stiffness among others.
In this study, the influence of 3d printing parameters: infill density, nozzle temperature,
printer speed, layer height has been investigated in order to analyze their impacts on young
modulus and yield strength of PLA material. The mechanical properties have been obtained from
tensile test according to ASTM D-638. A central composite design was used to perform the
experimentation. Furthermore, a model of prediction for young modulus and yield strength was
established based on experimental data using regression model and MANFIS model. Using the
obtained regression function model, a multi-objective optimization has been applied through the
desirability function method.
