¹ Data was obtained from green parts, printed using a Form 2, 100 μm, clear settings, without additional treatments. ² Data was obtained from parts printed using a Form 2, 100 µm, elastic settings, washed in Form Wash for 20 min, and postcured with Form Cure at 60 °C for 20 min. ³ Data was obtained from parts printed using a Form 2, 100 µm, flexible settings and postcured with 80.5 mW/cm² of 365 nm fluorescent light for 60 min. ⁴ Tensile testing was performed after 3+ hours at 23 °C using a Die C dumbbell and a 20 in/min crosshead speed.
