Mechanical properties of additively manufactured new polymer blend (polylactic acid-polycarbonate urethane) with varying printing layer thickness

The purpose of this study is to investigate the effect of varying printing layer thicknesses on the mechanical properties of a new 3D-printed polymer blend made of polylactic acid (PLA) and polycarbonate urethane (PCU). The specimen was created using the fused filament fabrication process. A univer...
