PCTG

PCTG is the line we did not have to praise ourselves. Independent community testing put CHCKX PCTG on the bench, measured it, and called it genuinely good. We will take that over any banner we could write. Ten colors, from Black and Silver to Olive Green, all wound to ±0.03 mm.

As a chemistry, PCTG is the step past PETG: the same water resistance and easy bed, with more impact toughness and better clarity as a class. It prints hot, and it rewards a machine that can hold 250 to 270 °C. If your brackets snap and your PETG looks cloudy, this is the upgrade path.
