The testing bars were created by casting the different resin formulations into the EVA mold and curing for 10 min in the Original Prusa Curing and Washing Machine (CW1S) (Prusa Research a.s., Czech Republic). The dogbones were stored in a climate chamber at 23°C, 50%RH for 1 week for conditioning before being tested. Mechanical tests were also performed on control material obtained from Prusament Resin Tough Anthracite Grey following the same procedure.
