AB - 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.
