MatterHackers PRO Series PCTG Filament
Durable, Low-Odor Filament with Superior Chemical and Impact Resistance
MatterHackers PRO Series PCTG Filament is a top-tier alternative to PETG, offering greater clarity, chemical resistance, and impact strength. It prints with low odor and delivers exceptional dimensional stability, making it an ideal choice for engineering-grade applications. With low shrinkage and no requirement for a heated chamber, it's well-suited for most open-source desktop 3D printers. PCTG’s amorphous structure gives it near isotropic shrinkage and three times lower moisture absorption than ABS. Proudly made in the USA, PRO Series PCTG delivers professional results for demanding projects.
Key Features of the MatterHackers PRO Series PCTG Filament:
- Superior chemical and impact resistance compared to PETG
- Low odor printing with excellent dimensional stability
- Amorphous structure for minimal shrinkage and near isotropic properties
- Low moisture absorption—3x lower than ABS
- Easy to print on open-source printers without a heated chamber
