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. Benefits of PCTG Include: Superior chemical resistance to ABS and PETG Very low odor while printing Amorphous structure giving it a low, near isotropic shrinkage Low moisture absorption, 3x lower than ABS Wide range of processing from 250-270°C Superior ductility vs. PETG PRINT RECOMMENDATION Filament Specifications: 1.75mm and 2.85mm +/- 0.05mm in diameter Recommended Print Settings: Extruder: 250-270°C Bed Temp: 70-80°C Heated Chamber: Not required Drying Instructions: 65°C for 4 hours.
