Abstract: 3d printing technologies are rapidly developing, having a strong impact on almost all areas of industry. The very known technology, the fused filament fabrication, mainly uses PLA to produce many objects used in a wide verity of applications. The aim of the study is to study the effect of the printing parameters such as layer height, feed rate, raster angle, and extrusion temperature on the electrical conductivity, the ultimate compression strength, and the water absorption ability of the printed objects. The results prove that the printing parameters have a significant effect on the mechanical and the electrical characteristics as well as the water absorption ability of the PLA printed samples.

Keywords: 3d Printing, PLA, Electrical Conductivity, Ultimate Compression Strength, Water Absorption, Printing Parameters
