C8 – REALIZAREA PRIN INGINERIE INVERSĂ CU IMPRIMANTA 3D A UNUI SUBANSAMBLU DIN PLASTIC PENTRU AUTOVEHICULE

Abstract: The aim of this work was to reverse engineer an assembly of
parts with the help of a 3D printer. For this purpose, as a set of parts, the handle
from the window lifting mechanism for a vintage car, Dacia 1310, was chosen.
The stages of reverse engineering in this case involved obtaining the dimensions
of the parts, 3d modeling in SolidWorks, finite element analysis and the
constructive optimization of the handle, respectively the physical creation of the
parts on the 3d printer and their subsequent assembly.

Keywords: reverse engineering, 3D printing, finite element analysis.
Cuvinte cheie: inginerie inversă, printare 3D, analiză cu element finit.

C5 – STUDIU PRIVIND INFLUENȚA PARAMETRILOR PROCESULUI DE IMPRIMARE 3D ASUPRA PRECIZIEI SUPRAFEȚELOR CIRCULARE

Abstract: The aim of this work is to analyze and optimize the 3D printing
process, focusing on the influence of printing parameters on the accuracy of
printed parts. Experiments were carried out with the Creality Ender 3 V2 Neo
printer, using various settings optimized by the RSM Design Expert software.
Two types of materials were used, PLA and PETG. The printed parts were
measured with a digital caliper and the deviations were calculated to determine
the best combinations of parameters. The size deviations of PLA parts were
smaller compared to PETG, printing nozzle size of 0.4 mm and a printing speed
of 30 mm/s produced the best results, fill degree of 90% was found to be optimal
for reducing deviations.

Keywords: FDM 3D printing, printing parameters, 3D printing process
Cuvinte cheie: printare 3D FDM, parametrii de printare, proces de printare 3D
