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 at $19.99 a kilo. 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.
