Abstract

The use of modern technologies, such as 3D printing techniques, creates the possibility of easy and rapid prototyping, being an important element in the design of technological processes. This modern process of elements producing of any shape consists in adding layer by layer of structural material. This is a lossless production, which is an additional advantage compared to conventional technologies such as CNC machining.The paper presents the results of research on the change in strength of samples made in 3D printing technology in the FDM (Fused Deposition Modeling) technique [1], depending on the method of printing and the percentage filling of the layer. The material used for printing was PLA (polylactide). Flat samples with dimensions 150x20x4 mm were printed using the XYZprinting da Vinci 3D printer localized in the Faculty of Production Engineering and Materials Technology at the Czestochowa Technical University.The produced samples were tested in a static tensile test. The research allowed to determine the impact (quantity / method / type) of the filling, and thus the amount of material used and the time of printing, on the strength of tested material. The presented results will enable the selection of optimal printing parameters in order to obtain the expected strength of the parts printed in the FDM technique.
