Layers optimisation of the pla parts formed by additive technologies

Abstract

Achieving required layer quality and its consistency is one of the key things for the effective implementation of the additive technologies, such as 3D printing. Experiments which were conducted at the Department of the Production Engineering, Faculty of Mechanical Engineering, University of Belgrade, were acquired optima parameters that led to better parts quality produced of PLA polymer with widely used commercial 3D printers. Parameters that were varied during the experiments were nozzle temperature and printing speed. After production, all parts were microscopically observed and their surfaces roughnesses were measured. It is established that differen values of these parameters can lead to diametrically different quality of layers that cause different quality of the printed parts.
