PHA Filament

The World's Most Eco-Friendly 3D Printing Filament. Made in the USA.

PHA — Polyhydroxyalkanoate — is a biopolymer made from natural materials. It looks, feels, and prints like plastic. But unlike standard plastics, it's biodegradable under all conditions — including home compost bins and, in the worst case, marine environments. No microplastics. No toxic breakdown products. No compromise between quality and sustainability.

Ambrosia PHA is made in the USA in partnership with EcoGenesis Biopolymers, and is the only PHA filament in our catalog with a verified compostability report, CPSIA compliance, and zero California Prop 65 listed chemicals (as of September 2025).
