¹ Data was obtained from green parts, printed using a Form 2, 100 μm, Clear settings, without additional treatments. ² Data was obtained from fired parts, printed using a Form 2, 100 μm, Ceramic settings, and washed and dried without an additional postcure. The parts were printed with a preapplied scale factor and fired using a 30 h schedule to a maximum firing temperature of 1275 °C, as laid out in the Formlabs usage guide.
