Dielectric Properties of 3D Printed Polylactic Acid

Figure 1

(a) Heat flow (endotherms up) of initial heating and subsequent cooling traces of PLA in the “as-printed” condition at a rate of 10 K/min. The glass transition temperature is determined using both the half step size () and onset temperature () methods. (b) DSC heating traces at a rate of 5 K/min, comparing PLA in the three conditions: semicrystalline (green), as-printed (black), and amorphous (red) conditions. The measurements are shifted vertically for clarity.
