The specimens were made using an additive technology. Polyethylene terephthalate glycol
(PETG) filament was used as the primary material. Three series with nine different printing
specimens (different printing parameters) were made. The Vickers microhardness (HV) of all
specimens was tested. The temperature treatments of specimens were done in a mold with NaCl
powder (230°C, 30 min), and in a chamber at low temperature (-200 °C, 30 cycles). It was
observed that the HV values oscillated, depending on the printing parameters, temperature
treatment, and locations. The microhardness was slightly higher on the bottom surface of the
specimens than on the top surface. For untreated specimens, the average microhardness measured
on the top and bottom surfaces was between 10.2 and 12.6 HV. For specimens treated in mold
with NaCl powder, changes in geometry were observed, together with an increased
microhardness of 11.0 to 13.5 HV. The treatment in a chamber at low temperature induced a...
decrease in microhardness, and the values were in the range of 9.0-9.5 HV. It is commonly
recognized that the microstructural alterations in amorphous polymers are directly correlated with
microhardness. In this connection, the basic idea is to show treatments that can significantly
improve/degrade the mechanical properties of this material in daily use.
