Zusammenfassung: | Fused deposition modeling is one of the most widely used 3-D printing
technologies, among other additive manufacturing processes, because it is
easy to use, can produce parts faster, and the cost of the finished part is
low. Printing processes and finished parts are often studied and
characterized using different techniques to collect mechanical, numerical,
thermal and dimensional data, with the aim of improving and optimizing the
result. The first part of this research is based on the observation of
temperature changes with a thermal imaging camera during the fused
deposition modeling printing process and during the cooling process after
printing. Specimens of polylactic acid and polylactic acid-X improved with
second-phase particles were prepared to compare the thermal and dimensional
properties of the two materials. The obtained results determined the
characteristic temperature behavior of the materials. In the second part of
the research, a 3-D optical scanner was used to verify the stability and
accuracy of the printed specimens over time. The proposed measurement period
showed that stabilization of the parameters takes place, and further
follow-up should be performed thereafter. |
