Possibilities of PLA material recycling for 3D printing purposes and influence on mechanical properties
 Sedláček, Vojtěch ; Krčma, Martin (referee) ; Koutecký, Tomáš (advisor)
This bachelor thesis deals with the comparison of mechanical properties of 3D PLA prints during recycling. The recycling cycle proceeded as follows: the printed FDM test specimens from the PLA were pulverised and re-extruded into a filament. This process was repeated three times. Test specimens were tested in each cycle. Tensile tests were performed at room and elevated temperatures. The results show that there was a slight increase in strength. Measurement of the melt flow index showed degradation of the material and its depolymerization.
