MAX-G™ PCTG
MAX-G™ PCTG is an excellent alternative to the ever-popular PETG. Both PCTG and PETG are polyesters and great printing materials, but PCTG offers improved clarity, chemical resistance and impact resistance vs. PETG – making it a more durable engineering-grade option for demanding applications. This material exhibits low shrinkage and excellent dimensional stability making it a go-to for engineering applications. PCTG does not require a heated chamber and is easily printed on most open-source desktop printers.
