American Filament Obsidian Black PCTG Filament

USA-made 1.75mm PCTG filament in a deep obsidian black for durable functional parts, clean prototypes, and dark-finish everyday prints.

• Material: PCTG, a PET-based copolyester often chosen when you want more toughness and chemical resistance than standard PLA.
• Color: Obsidian black with a crisp, versatile look that suits both utilitarian and display-focused prints.
• Print character: Strong layer adhesion, steady flow, and broad compatibility on many desktop printers without requiring a full enclosure.
• Finish: Surface sheen can shift from more matte to glossier depending on temperature and speed settings.
• Good fit for: brackets, organizers, housings, shop helpers, replacement parts, and general-purpose prints where a dark neutral color makes sense.

A practical black PCTG option when you want something tougher than PLA without wandering into a harder-to-manage specialty material.
