Abstract

The paper aims to present studies on the influence of technological process parameters on geometric accuracy and surface quality, when printing with 3D printers using FFF (FUSED FILAMENT FABRICATION) technology, using PLA wires, 1.75 mm. The research was carried out using a Creality Ender 3D printer, and the material used allowed the creation of a set of parts with medium geometric dimensions, with flat and circular surfaces. In order to determine the influences on printing accuracy, a number of technological process parameters of the printer have been varied, such as layer height, fill density, print speed, print temperature. PLA thread extrusion (printing temperature) and platform temperature (bed temperature). The 3D printed pieces were designed with SketchUp Pro 2020 in .stl format, also loaded with the printer control program, Ultimaker Cura 4.9.1, and finally and were translated into the .gcode print format. The parts were measured in terms of geometric accuracy, the accuracy of the reciprocal positions of the printed surfaces, as well as the quality of the surfaces in terms of the resulting roughness. There are a number of differences, in some cases significant, so that a number of conclusions can be drawn that can provide information on increasing the accuracy and quality of 3D printed parts in these cases.
