Strength properties of PLA material obtained by different models of FDM 3D printer

Abstract

Additive manufacturing is technology that is widely used to produce good quality products with complex geometries. One of the most popular additive technology today is fused deposition modelling (FDM). Literature review is showing that many parameters have influence on mechanical properties of FDM printed materials. Influence of FDM 3D printer model on strength properties of printed PLA (polylactic acid) material with different infill density is presented in this paper. Testing specimens are printed with five different 3D printer models of the same manufacturer with the same material and 3D printing parameters. Aim was to investigate 3D printer model influence on strength properties of 3D printed PLA material. The results of this study could be useful for users and researchers in order to select appropriate printer model for particular purpose considering optimal relation of PLA material strength properties and FDM 3D printer model.
